Seb Dermatitis can cover any area of the body producing Hair. Its basically an infection of the skin where oil glands and hair combine and your bodies imunbe system cannot fight the infection like normal people skin can!
Thats the problem with this disease is that there is no cure because once you wash your scalp with nizoral or whatever shampoo.. your skin still produces oil and bacteria which your skins immune system cannot fight! So its basically a revolving cycle of scratch, itch, rash, shedding...
