Dandruff refers to the flaking scalp which falls like snow flakes and settles on one’s brows, shoulders and clothes, but assumes an unpleasant, irritating condition associated with bacteria, in the case of excessive formation of scales on the scalp. These scales are formed from the horny layer of the skin.
The scaliness increases whenever the hair is brushed or rubbed. It may also appear as lumps or crusts on the scalp. Often there is itching as well, and the scalp may become red from scratching. The main causes of dandruff are – impairment of general health, toxic condition of the system brought on mainly by wrong feeding, constipation and lowered vitality due to infectious diseases. Other factors contributing to dandruff are emotional tension, harsh shampoos, exposure to cold and general exhaustion.
Numerous medicated shampoos are available in the market for the treatment of dandruff. Most of these, however, in the process of curing the disorder, cause irreparable damage to the hair roots because of the synthetic ingredients contained in them. The treatment of dandruff has to be largely constitutional, if a permanent cure is desired.
