Question: how often should i wash my hair to get rid of dandruff?
Answer: In fact, the most effective way to treat most dandruff is to use an over-the-counter shampoo, the American Academy of Dermatology (AAD) explains. 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.
