Symptoms and Complications:

If seborrheic dermatitis is the cause of dandruff, the symptoms usually appear gradually. The scalp becomes dry or greasy and feels itchy. As skin cells die, they turn to yellowish scales. A bad case of seborrheic dermatitis can also cause symptoms in other parts of the body. Yellowish or reddish scaling can appear on the hairline, in and around the ears, or on the nose and chest. The flakes associated with psoriasis look like silver scales, which may also commonly be apparent on the ears, extremities, trunk, palms, and soles.

The only reason for recommending this shampoo is my own experience by using it for dandruff. This is the best shampoo I've ever used. Now I'm dandruff free. Hope this information helps the people who are suffering with dandruff.
