Dandruff

Dandruff is dead skin that forms on the scalp. Skin dies and flakes off the body all the time, but if the rate is increased and the scaly flakes are not removed then they can be seen on the head. Normally skin cells die and are replaced around once a month, but with people with dandruff, the process is speeded up to about once a fortnight.

Dandruff is more common in the winter than the summer, probably because of the wearing of hats and central heating.

Treatment

There are some dandruff shampoos available, like Head & Shoulders.These shampoos contain selenium sulfide or zinc pyrithione, both of which slow down the rate of cell growth in the uppermost layer of skin on the head. Severe forms of dandruff, particlualy if accompanied by flaking or scaling on other parts of the body should be treated by a doctor, as there may be other causes or the patient may be suffering from seborrheic dermatitis( a condition that appears to be caused by a yeast infection) or psoriasis

Causes

There is speculation that dandruff is linked with Hair loss.
