Dandruff can be treated with lotions and shampoo (not commercial ones). Some people do have more oily scalp which cause visible flakes which we cause dandruff. There are some other conditions also which can present like flaking of the scalp and have to be ruled out. Do not apply oil on scalp as it will increase the problem. Please call me or contact me with photos through online consult option or visit me for treatment. The cause of hairloss has to be determined which may be due to nutritional deficiencies or female pattern baldness.
