A new postulate on two stages of dandruff: A clinical perspective

Dandruff (pityriasis capitis, seborrheic dermatitis confined to the scalp) is a disease that has been around for centuries despite several treatment options. Almost every day new players are entering the market with various antidandruff products, perhaps due to an increase in the incidence of dandruff all over the world. Interestingly, clinicians, especially dermatologists, gave little attention to this problem. At the end, the dandruff sufferer is puzzled by the array of antidandruff products with varied claims entering the market day by day. Why have we not achieved complete treatment success against dandruff? Is dandruff a disease or disorder? It seems that our understanding about dandruff perfectly fits into the famous saying of Albert Einstein, "as the area of light increases, so does the circumferences of darkness." Have dermatologists left dandruff unattended, only to be exploited by the personal care industry?
