What is dandruff and seborrheic dermatitis and what is the difference?
Dandruff is the formation of itchy white flakes that appear on the scalp and easily come off if you scratch your head. It occurs when the production of new skin cells speeds up.
There is no inflammation on the scalp. Dandruff can be unpleasant and difficult to get rid of.
If the scalp is red or inflamed than it is most like a case of seborrheic dermatitis, the flakes on the skin are scalier, often sticky and yellow and sometimes can be firmly stuck to the scalp.
