Question: how often should you wash your hair if you have bad dandruff?
Answer: You should shampoo your hair daily and swap in the anti-dandruff shampoo twice a week. If you have natural hair, you only need to use the anti-dandruff shampoo once a week. Myth #5: You don't need to exfoliate your scalp. Exfoliating your scalp every once in a while seems a little extreme, and for most of us it is.
