Dandruff is the flaking of dead tissue from the scalp in excessive amount and usually marked by itch on the scalp. The natural cycle for dead cells to come to the top of the scalp is about a month. Dandruff can be so frustrating, not just for the itch and the risk of losing your hair quality, but also the social embarrassment that it may cause. Imagine that white flakes shedding on your suit during your business meeting with a client, how embarrassing.
- Dry scalp
- Excess secretion from the sebaceous glands.
- Individual susceptibility.
- Allergic reaction to chemicals in hair care products, sometimes even shampoo which contains ketoconazole (usually used for dandruff medication).
- Psoriasis which may cause an accumulation of dead skin cells that form thick, silvery scales.
- Not washing/shampooing your hair regularly.
- Cold, dry winters are notorious for bringing on dandruff or making it worse.
- It is an inflammatory, chronic, noncontagious disease of the skin caused by allergy and hypersensitivity. It may cause intense itching.
- A yeast-like fungus (malassezia) which can irritate the skin on your scalp and cause more skin cells to grow.
However, dandruff is not contagious and can be controlled, though it may take a little patience and persistence. Here are some tips:
- Frequent shampooing.
- Using medicated shampoo prescribed by a physician.
- Managing your stress. Stress can trigger dandruff and worsen existing symptoms.
- Sunlight can help, but don’t sunbathe.
- You can also use the combination of lemon juice and olive or almond oil for a scalp massage.
- A diet that provides enough zinc, B vitamins and certain types of fats may help prevent dandruff.
