You are suffering from a condition known as seborrheic dermatitis
and tar based shampoo to be used every alternate days
topical lotion- steroid and salicylic acid
asked lotion every night
oral antihistamine like cetirizine
this will help in treating dandruff. Once the scalp is clear, you may use minoxidil solution for good hair growth.
Hope that answered your query.
