Dandruff, or its medical term seborrheic dermatitis is the flaking of the skin on the scalp in response to inflammation. The source of the inflammation can be allergies to cosmetic products, stress, overproduction of oil from the scalp’s glands, or overexposure to high heat or extreme cold. Tips to prevent dandruff include keeping the scalp healthy, carefully selecting hair products, allowing some exposure to the sun, and following a health diet.
Maintain Scalp Health
Scalp health is directly related to dandruff. A scalp that is oily can become irritated due to clogged pores and a buildup of both oils and skin cells that shed irregularly. Regular shampooing can help prevent dandruff, especially in people who have greasy skin and hair, explains the National Institutes of Health resource Medline Plus. Shampooing every day may not be the answer for everyone, as some people might experience a drying of the scalp which can lead to itching and flaking of the skin as well. Each individual should experiment with their hair-washing schedule to determine the frequency that helps prevent dandruff.
Keeping the scalp healthy through diet is another important part of avoiding the tell-tale white flakes falling from the hair, according to the Mayo Clinic. Vitamin B, zinc, omega 3 fatty acids and lots of water can maintain a healthy scalp, which reduces the likelihood of dermatitis and other scalp conditions. The American Heart Association recommends two weekly 3 oz. servings of salmon, albacore tuna, herring or lake trout as sources of omega 3. People who do not consume these nutrients through diet should ask their doctor about taking dietary supplements.
Limit Styling Aids
People who have dandruff may be able to prevent the embarrassing condition by cutting back on their styling aids, and choosing products that are alcohol-free. The irritation that leads to dandruff may be caused by an allergic reaction to ingredients in products that are heavily scented, and alcohol can dry out the scalp skin, creating itching and flaking. Using hairsprays, gels and mousses that build up on the scalp can make the skin and hair more oily, which is another factor in the production of dandruff.
Catch Some Rays
The Mayo Clinic suggests that exposing the hair and scalp to sunlight may help prevent dandruff in some cases. Overexposure to the sun can cause skin damage and heightens the risk of skin cancer, so sun protection is important to remember. Wear a sunblock lotion that blocks both UVA and UVB rays, as well as sunglasses to protect the eyes and delicate area prone to “crow’s feet.” The Mayo Clinic does not give a recommended length of time for sun exposure, but does explain that prolonged periods of sunbathing are not necessary.
