Dandruff is generally produced when the skin of the scalp exfoliates excessively.
The whitish flakes in the hair which generally falls on our shoulder/collar, are known as Dandruff. Excessive Dandruff becomes an eyesore and also causes itchiness on the scalp/skin.Dandruff is not caused by poor hygiene, although it may be visible more prominently if we do not wash our hair regularly. Stress and cold weather may also make dandruff worse.
Dandruff is generally treated by using topical anti-yeast lotions and shampoos or cortisone-based creams.
