Hi there swethi. I note your problem with interest. You seem to have a case of seborrheic dermatitis
of scalp cannot be ruled out. Depending on which part of the world you are from, I would be happy to recommend a good dermatologist
for you to visit. In the meantime try 2 % ketoconazole
shampoo & leave it on your wet scalp for 10-15 mts contact alternate days for a wek or two Good luck & do visit your dermatologist therafter. Cheers!
