what is dandruff

Dandruff is a common scalp condition that causes the skin on the scalp to flake. It is not contagious or serious, but it can be embarrassing and difficult to treat. Dandruff is a mild form of seborrheic dermatitis, and the exact cause is not known, but its likely a combination of factors such as irritated, oily skin, dry skin, a yeast-like fungus called Malassezia that feeds on oils on the scalp, and sensitivity to hair care products. Anyone can have dandruff, but certain factors can make you more susceptible, such as age, being male, and certain illnesses. Dandruff can be treated with a gentle daily shampoo, and if that doesnt work, a medicated shampoo may help. The most effective way to treat and control dandruff is to use dandruff shampoo and scalp treatments. Over-the-counter dandruff shampoo can control dandruff, and the most common treatment for dandruff is over-the-counter anti-dandruff shampoos that contain salicylic acid, zinc, or selenium sulfide.
