You might probably be having seborrheic dermatitis
To treat the same use a ketoconazole
tar based shampoo like konaz ct every alternate days. Also apply a antifungal steroid based lotion over scalp daily like candid b lotion. Your hair fall
could be due to dandruff, so once the dandruff is gone, hair fall might stop. Minoxidil
solution 2 percent too can be used later on to promote hair growth.
Hope that answers your query. Take care.
