Thanks for writng to us.
You seem to be suffering from severe dandruff known as seborrheic dermatitis
Use a ketoconazole
and tar based shampoo like protar k or konaz ct every other day. Apply over scalp and keep it for 10 min then wash off. Use a steroid salicylic acid
based lotion like topisal or halox s in night. Avoid oiling your scalp. Also make it a point to visit a dermatologist
Hope that helped.
