Go to L'Occitane,you have it in Vilagio.
I had different problem,since i came here my hair started to get oily in very short period of time so i had to wash it every day!Tried every possible expensive shampoo that i found in the pharmacy and nothing worked.
But when i discovered L'Occitane i fixed the problem from the first time i used the shampoo.Go to the shop and tell them you are problem i am sure they will give you something that can help you with your hair.The price of the shampoos are around 80qr and they are organic+they are not tested on animals .good luck.
