Dandruff is not to use vinegar to wash your hair, because vinegar is an acid agent, and acidic, so if you use vinegar to wash your hair, it is easy to cause hair damage, but also easy to cause damage to the cuticle of the scalp, so try not to use vinegar to wash your hair. Of course, if the dandruff is really more, belongs to seborrheic dermatitis, you can use ketoconazole shampoo to wash your hair appropriately, or use coal tar shampoo to wash your hair. If the dandruff is more, and accompanied by different degrees of itching, you can use the second generation of antihistamines orally, usually one a day, can also be appropriate with some proprietary Chinese medicines, such as oral anti-wind and anti-itch granules and so on.
