My 11 year old daughter has dandruff problem since almost a year. And a little portion of her scalp in front has white patches which start flaking. She gets this problem just few hours after washing hair. She also keeps getting pimples on her face ,specially around the nose and forehead. What treatment can be done for this problem suitable for 11 year old. I have tried some anti acne cream, but they are not very effective. The hair on scalp becomes oily after 2 days,but the length of the hair is dry. Please suggest some treatment. Thanks.
