Dandruff is sometimes confused with dried shampoo. This usually occurs when hair isn’t rinsed properly. Dandruff is not an organism like Lice; it is just dead skin that accumulates in the scalp. Dandruff is unlikely to be the cause of hair loss, although excess Sebum which is linked to Dandruff contains DHT (Dihydrotachysterol), the primary agent in Alopecia.
