Why Do You Have Scalp Dandruff?
Scalp dandruff is a common condition that affects many people. It is characterized by the presence of white or yellow flakes on the scalp and hair, which may be accompanied by itching, redness, and inflammation. Scalp dandruff can have various causes, ranging from skin disorders to lifestyle factors. In this section, we will explore some of the most common reasons behind scalp dandruff, based on information from Mao Jue Hair Clinic and Health Goo.
Seborrheic Dermatitis:
Seborrheic dermatitis is a chronic inflammatory skin condition that affects areas with high sebum production, such as the scalp, face, and chest. It often presents as oily, large, and yellowish flakes on the scalp, along with redness and itching. The exact cause of seborrheic dermatitis is unknown, but it may be related to genetic factors, hormonal changes, immune system dysfunction, or environmental triggers. According to a review by Dessinioti and Katsambas (2013), seborrheic dermatitis affects about 3-5% of the general population, and it is more prevalent in men than women.
Allergic Eczema:
Allergic eczema, also known as contact dermatitis, is a type of allergic reaction that occurs when the skin comes into contact with a substance that triggers an immune response. It appears as dry and fine flakes on the scalp, along with redness, swelling, and itching. Some common allergens that can cause allergic eczema on the scalp include hair products, fragrances, metals, plants, or latex. Allergic eczema can be diagnosed by patch testing, which involves applying small amounts of potential allergens on the skin and observing for any reactions. A study by Thyssen et al. (2017) found that allergic eczema affects about 20% of the population in industrialized countries.
Psoriasis:
Psoriasis is a chronic autoimmune disease that causes the skin cells to grow faster than normal, resulting in thick, silvery-white scales on the skin surface. Psoriasis can affect any part of the body, but it is most common on the scalp, elbows, knees, and lower back. Psoriasis can cause itching, burning, and bleeding on the affected areas, as well as psychological distress and social stigma. The exact cause of psoriasis is unknown, but it may be influenced by genetic, environmental, and immunological factors. According to a report by the World Health Organization (2016), psoriasis affects about 2-3% of the global population, and it is more common in colder climates.
Oily Scalp:
Oily scalp is a condition where the sebaceous glands on the scalp produce excess sebum, which is a natural oil that lubricates and protects the skin and hair. Oily scalp can cause the scalp to become greasy, sticky, and prone to dandruff. Oily scalp can be caused by genetic factors, hormonal changes, stress, diet, or improper scalp care. Weather conditions also influence the rate of scalp cell turnover, with a 10% increase in oil secretion for every degree rise in temperature. Thus, many people experience increased oiliness during summer, leading to dandruff due to accelerated shedding of dead skin cells. A study by Piérard-Franchimont et al. (2006) found that oily scalp affects about 15% of the population, and it is more common in men than women.
Stress and Emotions:
Stress and emotions can have a significant impact on the health and appearance of the scalp. The scalp naturally hosts Malassezia, a yeast-like fungus that feeds on sebum and helps maintain the scalp’s microbial balance. Under normal circumstances, the quantity of Malassezia is effectively controlled by the immune system and the skin barrier. However, excessive stress or emotional instability can lead to overgrowth of Malassezia, disrupting the scalp’s microbial balance and causing inflammation, irritation, and dandruff. A study by Misery et al. (2019) found that stress and emotions are associated with increased severity and frequency of scalp disorders, such as dandruff, seborrheic dermatitis, and psoriasis.
Stimulating Diet:
Diet plays an important role in maintaining the health and beauty of the scalp. A balanced and nutritious diet can provide the essential vitamins, minerals, and antioxidants that support the scalp’s function and structure. On the other hand, a stimulating diet that is high in fried, high-sodium, high-sugar, and spicy foods can cause inflammation, oxidative stress, and hormonal imbalance, which can affect the scalp’s condition and lead to dandruff. Moreover, excessive caffeine intake (e.g., tea, coffee) can stimulate the nervous system and increase the secretion of sebum and sweat, creating a favorable environment for the growth of Malassezia. A study by Danby et al. (2013) found that a high-glycemic diet can worsen the symptoms of dandruff and seborrheic dermatitis.
Irregular Sleep Patterns:
Irregular sleep and insufficient sleep can reduce the body’s immunity, leading to abnormal keratin metabolism and worsening of scalp disorders. Keratin is a protein that forms the main component of the skin and hair. It is produced by keratinocytes, which are the most abundant cells on the epidermis. Keratinocytes undergo a process of differentiation, maturation, and desquamation, which is regulated by the circadian rhythm. The circadian rhythm is the body’s internal clock that controls the sleep-wake cycle and various physiological functions. When the circadian rhythm is disrupted by irregular sleep patterns, the keratinocytes’ function and turnover are affected, resulting in impaired skin barrier, increased inflammation, and increased susceptibility to dandruff. A study by Oyetakin-White et al. (2015) found that poor sleep quality can impair the skin’s ability to recover from environmental stressors, such as UV exposure and low humidity.
Improper Scalp Care:
Improper scalp care can also contribute to the occurrence and recurrence of dandruff. Many people experiencing dandruff do not necessarily have oily scalps. Excessive cleaning or using inappropriate shampoos can strip away the natural oils and moisture from the scalp, causing it to become dry, irritated, and flaky. Conversely, insufficient cleaning or using shampoos that are too mild can leave behind dirt, oil, and residue on the scalp, creating a breeding ground for bacteria and fungi. The use of improper shampoos may also cause scalp sensitivity, peeling, and dandruff due to the presence of harsh chemicals, fragrances, or preservatives. Therefore, it is important to choose a shampoo that suits one’s scalp type, condition, and preference, and to follow the instructions on how to use it properly.
Organ Dysfunction:
Abnormalities in organ function, such as gastrointestinal issues, nutritional imbalances, and endocrine disorders, can hinder nutrient absorption, reduce immunity, and affect scalp health, leading to dandruff. For example, gastrointestinal issues, such as dysbiosis, gastritis, or ulcers, can impair the digestion and assimilation of food, resulting in deficiencies of vitamins, minerals, and amino acids that are essential for the scalp’s function and structure. Nutritional imbalances, such as anemia, hypothyroidism, or diabetes, can alter the hormonal levels and metabolic processes that regulate the scalp’s condition and sebum production. Endocrine disorders, such as polycystic ovary syndrome (PCOS) or Cushing’s syndrome, can cause excess production of androgens, which can stimulate the sebaceous glands and increase the risk of dandruff and seborrheic dermatitis. A study by Borda and Wikramanayake (2015) found that dandruff and seborrheic dermatitis are associated with various systemic diseases, such as Parkinson’s disease, HIV, and epilepsy.
Types of Scalp Dandruff
Scalp dandruff can be classified into two types based on the appearance and cause of the flakes: dry and oily.
| Dry Scalp Dandruff | Oily Scalp Dandruff |

Should You Wash Your Hair Every Day?
Many people think that washing their hair every day can help get rid of scalp dandruff, especially if they have oily scalp. However, this is not always the case. Washing your hair too frequently can strip away the natural oils that protect your scalp and hair, making them more prone to dryness, irritation, and damage. This can also disrupt the balance of the scalp microbiome, which is the community of microorganisms that live on your skin and help keep it healthy. A disrupted scalp microbiome can lead to inflammation, infection, and more dandruff.
According to a recent study by The Journal of the American Academy of Dermatology, the optimal frequency of shampooing depends on various factors, such as hair type, scalp condition, lifestyle, and personal preference. The study suggests that people with fine, straight, or oily hair may benefit from washing their hair more often, while people with coarse, curly, or dry hair may benefit from washing their hair less often. The study also recommends that people with scalp dandruff use a medicated shampoo that contains anti-fungal or anti-inflammatory ingredients, such as zinc pyrithione, ketoconazole, or salicylic acid, at least twice a week.
The bottom line is that there is no one-size-fits-all answer to how often you should wash your hair. The best way to find out what works for you is to experiment with different frequencies and products, and observe how your scalp and hair respond. You should also consult a dermatologist if you have any concerns or questions about your scalp health.
How to Choose Anti-Dandruff Shampoo?
Choosing the right anti-dandruff shampoo can make a big difference in your scalp health and hair quality. However, not all shampoos are created equal, and different types of dandruff may require different ingredients and formulations. Here are some tips on how to select the best anti-dandruff shampoo for your specific condition:
| Type of Dandruff | Causes | Recommended Ingredients | Examples of Products |
|---|---|---|---|
| Dry Scalp Dandruff | Lack of moisture, cold weather, harsh chemicals, over-washing | Moisturizing agents, gentle cleansers, natural oils | Head & Shoulders Dry Scalp Care, Dove DermaCare Scalp Soothing Moisture, OGX Nourishing Coconut Milk Shampoo |
| Oily Scalp Dandruff | Excess sebum production, hormonal imbalance, poor hygiene, stress | Zinc pyrithione, salicylic acid, coal tar, tea tree oil | Neutrogena T/Gel Therapeutic Shampoo, Selsun Blue Medicated Maximum Strength, Paul Mitchell Tea Tree Special Shampoo |
| Fungal Scalp Dandruff | Malassezia yeast overgrowth, weakened immune system, genetic predisposition | Ketoconazole, selenium sulfide, ciclopirox | Nizoral A-D Anti-Dandruff Shampoo, Selsun Blue Naturals Itchy Dry Scalp, Loprox Shampoo |
| Inflammatory Scalp Dandruff | Allergic eczema, psoriasis, contact dermatitis, autoimmune disorders | Corticosteroids, antihistamines, immunosuppressants | Clobex Shampoo, Capex Shampoo, Betnovate Scalp Application |
When choosing an anti-dandruff shampoo, it is important to follow the directions on the label and use it as instructed. Some shampoos may require longer contact time with the scalp, while others may need to be used more or less frequently depending on the severity of the condition. You should also consult your doctor, pharmacist, or pharmaceutical consultant before using any prescription-strength shampoos, as they may have side effects or interactions with other medications. If your dandruff does not improve after four weeks of using an anti-dandruff shampoo, or if you experience any signs of infection, inflammation, or irritation, you should seek medical attention as soon as possible.
Anti-dandruff shampoos are not the only solution for scalp dandruff. You should also adopt a healthy lifestyle and hair care routine that can help prevent and reduce dandruff. Some of the things you can do include:
- Drink plenty of water and eat a balanced diet rich in omega-3 fatty acids, zinc, vitamin B, and antioxidants.
- Avoid stress and get enough sleep, as they can affect your hormone levels and immune system.
- Wash your hair regularly, but not too often, as over-washing can strip your scalp of its natural oils and moisture.
- Use lukewarm water and gentle shampoos that are suitable for your hair type and scalp condition.
- Avoid scratching, picking, or rubbing your scalp, as this can damage your skin and cause infections.
- Limit your use of styling products, hair dryers, curling irons, and other tools that can irritate your scalp or cause buildup.
- Change your pillowcases, towels, and hats frequently, as they can harbor dirt, oil, and bacteria.
- Protect your scalp from sun exposure, extreme temperatures, and environmental pollutants.
By following these tips, you can choose the best anti-dandruff shampoo for your scalp and enjoy a flake-free, healthy, and beautiful hair.
How to Improve Scalp Dandruff
Scalp dandruff can be a frustrating and embarrassing condition, but it can also be improved with some simple changes in your daily habits. Here are some tips to help you get rid of those pesky flakes and restore your scalp health.
Focus on Diet and Lifestyle:
What you eat and how you live can affect your scalp condition. Some foods, such as spicy, greasy, or sugary foods, can trigger or worsen dandruff by increasing inflammation and sebum production. Therefore, it is advisable to avoid or limit these foods and opt for more balanced and nutritious meals that include fruits, vegetables, whole grains, lean proteins, and healthy fats. These foods can provide your body and scalp with essential vitamins, minerals, antioxidants, and omega-3 fatty acids that can help reduce inflammation, regulate sebum, and support skin barrier function.
Moreover, your lifestyle habits can also influence your scalp health. Stress, lack of sleep, smoking, alcohol consumption, and exposure to environmental pollutants can all contribute to dandruff by impairing your immune system, disrupting your hormonal balance, and damaging your scalp skin. Therefore, it is important to manage your stress levels, get enough quality sleep, quit smoking, moderate your alcohol intake, and protect your scalp from sun, wind, and dust. These habits can help you maintain a healthy scalp and a positive mood.
Proper Scalp Cleansing:
One of the key factors in preventing and treating dandruff is keeping your scalp clean and hygienic. This can help you remove excess oil, dead skin cells, dirt, and bacteria that can accumulate on your scalp and cause irritation, inflammation, and flaking. However, proper scalp cleansing does not mean over-washing or under-washing your hair, as both can have negative effects on your scalp condition. Over-washing can strip your scalp of its natural oils and moisture, making it dry, itchy, and prone to flaking. Under-washing can leave your scalp oily, greasy, and clogged, creating a favorable environment for dandruff-causing fungi and bacteria to grow and multiply.
Therefore, the optimal frequency of scalp cleansing depends on your scalp type, hair texture, and personal preference. Generally, it is recommended to wash your hair at least once every two or three days, or more often if your scalp is oily or sweaty. You should also use a gentle shampoo that is suitable for your scalp type and hair condition, and avoid harsh chemicals, fragrances, or dyes that can irritate or dry out your scalp. Additionally, you should rinse your hair thoroughly with lukewarm water, as hot water can damage your scalp and hair, and cold water can leave residues that can cause buildup and flaking.
Choose and Use Suitable Shampoo:
Not all shampoos are created equal, and some may work better for your scalp than others. Depending on the type and severity of your dandruff, you may need to use a specific shampoo that can address the underlying cause and symptoms of your condition. For example, if your dandruff is caused by a fungal infection, you may need to use an antifungal shampoo that contains ingredients such as ketoconazole, zinc pyrithione, selenium sulfide, or tea tree oil. These ingredients can help kill the fungi that cause dandruff and reduce inflammation, itching, and scaling. If your dandruff is caused by excessive sebum production, you may need to use a shampoo that contains salicylic acid, coal tar, or sulfur. These ingredients can help dissolve and remove the excess oil and dead skin cells that form dandruff and clog your pores. If your dandruff is caused by dry scalp, you may need to use a moisturizing shampoo that contains ingredients such as glycerin, aloe vera, or honey. These ingredients can help hydrate and nourish your scalp and prevent it from flaking and itching.
When using a shampoo for dandruff, you should follow the instructions on the label and apply it correctly to your scalp. You should massage the shampoo gently into your scalp with your fingertips, not your nails or a comb, as these can scratch and damage your scalp. You should also leave the shampoo on your scalp for a few minutes to allow it to work, and then rinse it off thoroughly with lukewarm water. You may need to repeat the process if your scalp is very oily or dirty. You should also avoid using conditioner on your scalp, as this can weigh down your hair and cause buildup and flaking. You can apply conditioner to the ends of your hair if needed, and rinse it off well.
Use Therapeutic Anti-Dandruff Shampoos:
If your dandruff is mild or occasional, you may be able to control it with regular shampoos that suit your scalp type and hair condition. However, if your dandruff is moderate or severe, or does not improve with regular shampoos, you may need to use a therapeutic anti-dandruff shampoo that can target the specific cause and symptoms of your condition. Therapeutic anti-dandruff shampoos are specially formulated with active ingredients that can help treat dandruff and improve your scalp health. Some of the common ingredients and their functions are:
| Ingredient | Function |
|---|---|
| Ketoconazole | An antifungal agent that can kill the fungi that cause dandruff and seborrheic dermatitis |
| Zinc pyrithione | An antifungal and antibacterial agent that can reduce the growth of fungi and bacteria that cause dandruff and scalp infections |
| Selenium sulfide | An antifungal and keratolytic agent that can slow down the turnover of skin cells and prevent the formation of dandruff and seborrheic dermatitis |
| Salicylic acid | A keratolytic and comedolytic agent that can dissolve and remove the excess oil and dead skin cells that form dandruff and clog the pores |
| Coal tar | A keratolytic and anti-inflammatory agent that can reduce the production of skin cells and relieve the itching and scaling of dandruff and psoriasis |
| Sulfur | A keratolytic and antibacterial agent that can exfoliate and cleanse the scalp and prevent the growth of bacteria that cause dandruff and folliculitis |
| Tea tree oil | A natural antifungal, antibacterial, and anti-inflammatory agent that can inhibit the growth of fungi and bacteria that cause dandruff and scalp infections, and soothe the irritation and inflammation of the scalp |
When using a therapeutic anti-dandruff shampoo, you should follow the directions on the label and consult your doctor or pharmacist if you have any questions or concerns. You should also be aware of the possible side effects and precautions of using these shampoos, such as skin irritation, allergic reactions, discoloration of hair, or photosensitivity. You should also use these shampoos only as needed, and not more than the recommended frequency or duration, as overuse can cause adverse effects or reduce their effectiveness. You should also alternate these shampoos with regular shampoos to avoid over-drying or irritating your scalp.
Adjust Washing Frequency:
One of the factors that can affect your scalp dandruff condition is how often you wash your hair. Washing too frequently or too infrequently can disrupt the natural balance of your scalp and cause irritation, dryness, or oiliness. Therefore, it is important to adjust your washing frequency based on your scalp type and the external environment.
A general guideline is to wash your hair according to your scalp’s oiliness level: dry, normal, or oily. Dry scalps tend to produce less oil and may benefit from washing 2-3 times a week, while oily scalps may need daily washing to remove excess sebum and prevent clogging of pores. Normal scalps can wash 3-4 times a week, depending on their preference and lifestyle. However, these are not fixed rules, and you should also consider the seasonal changes that can affect your scalp condition. For example, during autumn and winter when the air is dry and cold, your scalp may produce less oil and become more sensitive, so you may want to reduce your washing frequency and use a moisturizing shampoo. On the other hand, during summer when the weather is hot and humid, your scalp may produce more oil and sweat, which can create a favorable environment for dandruff-causing fungi, so you may want to increase your washing frequency and use an anti-fungal shampoo.
According to a study by Piérard-Franchimont et al. (2010), washing frequency can have a significant impact on the severity of scalp dandruff. The researchers found that washing the hair every day or every other day resulted in a lower dandruff score than washing the hair once a week or less. They also found that using an anti-dandruff shampoo was more effective than using a regular shampoo, regardless of the washing frequency. Therefore, they recommended that people with scalp dandruff should wash their hair at least every other day with an anti-dandruff shampoo to achieve optimal results.
Avoid Scratching with Nails and Combs:
Another factor that can worsen your scalp dandruff condition is scratching your scalp with sharp objects like nails and combs. Scratching can damage the skin barrier, cause inflammation, and increase the risk of infection. It can also spread the flakes and fungi to other parts of your scalp and hair, making the problem more visible and difficult to treat. Therefore, it is advisable to avoid scratching your scalp as much as possible, especially when it is wet or irritated.
If you feel an itch on your scalp, try to gently massage it with your fingertips instead of using your nails or combs. You can also apply some soothing products like aloe vera gel, tea tree oil, or apple cider vinegar to your scalp to relieve the itchiness and reduce the inflammation. These natural remedies have anti-inflammatory, anti-fungal, and anti-bacterial properties that can help improve your scalp health and prevent dandruff. However, you should always do a patch test before applying any new product to your scalp, as some people may have allergic reactions or sensitivities to certain ingredients.
A study by Satchell et al. (2002) showed that using a shampoo containing 5% tea tree oil for four weeks significantly reduced the severity of scalp dandruff compared to using a placebo shampoo. The tea tree oil shampoo also improved the scalp’s itchiness, greasiness, and scaliness. The researchers concluded that tea tree oil has a potential role in the treatment of scalp dandruff, as it can inhibit the growth of the fungi that cause dandruff and soothe the scalp’s inflammation.
Use Lukewarm Water:
The temperature of the water you use to wash your hair can also affect your scalp dandruff condition. Using hot water can strip away the natural oils and moisture from your scalp and hair, leaving them dry and prone to flaking. It can also stimulate the blood circulation and sebum production of your scalp, which can create more oiliness and irritation. Therefore, it is better to use lukewarm water to wash your hair, as it can cleanse your scalp and hair without causing too much damage or discomfort.
When washing your hair, you should also avoid rubbing or scrubbing your scalp too hard, as this can cause friction and abrasion that can damage the skin and hair follicles. Instead, you should gently massage your scalp with your fingertips in circular motions, using a mild shampoo that suits your scalp type. You should also rinse your hair thoroughly with lukewarm water, making sure that no shampoo residue is left behind, as this can clog your pores and cause inflammation. After washing your hair, you should gently pat it dry with a soft towel, avoiding rubbing or wringing it, as this can cause breakage and frizz.
A study by Lee et al. (2015) investigated the effects of water temperature on scalp and hair condition. They found that washing the hair with hot water (55°C) increased the scalp’s sebum secretion, pH, and transepidermal water loss, compared to washing the hair with warm water (35°C) or cold water (15°C). They also found that washing the hair with hot water decreased the hair’s tensile strength and increased its friction coefficient, compared to washing the hair with warm water or cold water. They suggested that washing the hair with hot water can damage the scalp and hair structure and function, and recommended that washing the hair with warm water or cold water can be beneficial for maintaining scalp and hair health.
Frequently Asked Questions
Can Scalp Dandruff Lead to Hair Loss?
Many people wonder if scalp dandruff can cause hair loss or thinning. The answer is not straightforward, as dandruff itself does not directly damage the hair follicles or affect the hair growth cycle. However, dandruff can indirectly lead to hair loss in some cases, such as:
- Scratching. The itchiness caused by dandruff can make you scratch your scalp frequently, which can injure the hair follicles and cause inflammation, infection, or scarring. Scratching can also break the hair shafts and make them fall out more easily. To prevent this, avoid scratching your scalp and use a gentle shampoo that can soothe the itchiness and reduce the flakes.
- Seborrheic dermatitis. This is a more severe form of dandruff that affects not only the scalp but also other areas of the body, such as the face, chest, and back. It causes red, scaly, and oily patches on the skin that can be very itchy and flaky. Seborrheic dermatitis can also affect the hair follicles and cause hair loss in some people, especially if the condition is chronic or untreated. To treat seborrheic dermatitis, you may need to use a medicated shampoo that contains ingredients such as ketoconazole, selenium sulfide, or coal tar. You may also need to consult a dermatologist for prescription medications or other therapies.
- Androgenetic alopecia. This is a common type of hair loss that affects both men and women, and is also known as male or female pattern baldness. It is caused by a combination of genetic and hormonal factors that make the hair follicles shrink and produce thinner and shorter hairs. Androgenetic alopecia can be worsened by dandruff, as the inflammation and fungal overgrowth on the scalp can interfere with the normal functioning of the hair follicles and accelerate the hair loss process. To prevent or treat androgenetic alopecia, you may need to use topical or oral medications that can block the effects of the hormones that cause hair loss, such as minoxidil or finasteride. You may also consider other options such as hair transplantation or low-level laser therapy.
As you can see, dandruff can be a contributing factor to hair loss, but it is not the sole or direct cause. By treating your dandruff effectively and taking good care of your scalp and hair health, you can prevent or reduce the risk of hair loss.
How to Prevent Scalp Dandruff from Coming Back?
Scalp dandruff can be a recurring problem for many people, as it can be triggered by various factors such as stress, weather changes, hormonal fluctuations, or improper hair care. However, there are some effective strategies that can help you keep scalp dandruff at bay and prevent it from coming back, such as:
- Wash your hair regularly. Washing your hair with a mild shampoo can help remove the excess oil, dirt, and dead skin cells from your scalp that can feed the dandruff-causing fungi. However, washing your hair too often or too harshly can also strip your scalp of its natural oils and moisture, which can make it more prone to dryness, irritation, and flaking. Therefore, you need to find a balance between washing your hair enough to keep it clean and healthy, but not too much to make it dry and damaged. The optimal frequency of washing your hair depends on your hair type, scalp condition, and lifestyle, but generally, it is recommended to wash your hair every 2-3 days.
- Use a dandruff shampoo. If you have mild to moderate dandruff, you may benefit from using a dandruff shampoo that contains active ingredients that can fight the fungi, reduce the inflammation, and control the scaling on your scalp. Some of the common ingredients that can help with dandruff are pyrithione zinc, salicylic acid, coal tar, selenium sulfide, and ketoconazole. You can find these ingredients in various over-the-counter or prescription shampoos, and you can use them according to the instructions on the label or as directed by your doctor. You may need to use a dandruff shampoo regularly or intermittently, depending on the severity and recurrence of your dandruff.
- Moisturize your scalp. Keeping your scalp hydrated and nourished can help prevent it from becoming dry, itchy, and flaky. You can moisturize your scalp by using a conditioner after shampooing, applying a scalp oil or serum, or using a hydrating mask or treatment. You can also use natural remedies such as aloe vera, coconut oil, or tea tree oil, which have anti-inflammatory, antifungal, and moisturizing properties that can benefit your scalp. However, be careful not to over-moisturize your scalp or use products that are too heavy or greasy, as they can clog your pores and make your scalp more oily and prone to dandruff.
- Avoid triggers. There are some factors that can trigger or worsen your dandruff, such as stress, cold and dry weather, hormonal changes, or certain foods. You can try to avoid or minimize these triggers by managing your stress levels, using a humidifier or moisturizer in winter, adjusting your diet, or consulting your doctor about your hormonal issues. You can also avoid using hair products that contain alcohol, fragrances, or other ingredients that can irritate your scalp or cause an allergic reaction. Additionally, you can avoid wearing hats, helmets, or other items that can trap heat and sweat on your scalp, which can create a favorable environment for the dandruff-causing fungi.
By following these strategies, you can prevent scalp dandruff from coming back and enjoy a healthy and flake-free scalp.
Is Scalp Dandruff Contagious?
One of the most common myths about scalp dandruff is that it is contagious, meaning that you can catch it from someone else or pass it on to others. However, this is not true. Scalp dandruff is not a contagious or infectious condition, and you cannot get it from sharing personal items such as combs, brushes, hats, or pillows with someone who has dandruff. Nor can you transmit it to others by physical contact such as hugging, kissing, or shaking hands.
The reason why scalp dandruff is not contagious is that it is not caused by a foreign agent such as a bacteria, virus, or parasite that can be transferred from one person to another. Rather, it is caused by a combination of factors that are present on everyone’s scalp, such as the natural oils, the dead skin cells, and the fungi. These factors interact differently on different people’s scalps, depending on their individual characteristics, such as their skin type, hair type, scalp pH, immune system, and genetic predisposition. For some people, these factors create an imbalance on the scalp that leads to inflammation, irritation, and excessive flaking, resulting in dandruff. For others, these factors do not cause any problems and they have a normal and healthy scalp.
Therefore, scalp dandruff is not something that you can catch or spread, but rather something that you can develop or prevent depending on your own scalp condition and how you take care of it. By treating your dandruff effectively and following good scalp hygiene practices, you can improve your scalp health and prevent dandruff from affecting your quality of life.
