Dandruff is a long term condition of the scalp, in which small pieces of dry and dead skin appearing as white powder are visible on the hair and clothes. It is known to cause itching on the scalp. The dandruff often fall on the shoulder and forehead causing embarrassment.

Though dandruff is a long term condition, it is not permanent. It can be treated by various methods like antifungal medicines, regularly washing the hair, and a few home remedies like applying lemon juice.

There are several causes of dandruff. A fungus called malassezia is found on the scalp of most adults which causes dandruff. Dry skin can also cause dandruff.

Dandruff can be be controlled by the home remedies and various antidandruff shampoos available in the market. However, if they dont work and the scalp becomes red and itchy continuously, one must consult a doctor who is a skin specialist (dermatologist) or a trichologist.

When the anti-dandruff preparations which are available in the market fail to control dandruff, and dandruff continuously causes red and itchy scalp, then it requires medical treatment by a doctor who is specialized to treat skin diseases.
