How Often Should You Wash Your Hair

When it comes to your scalp health, dermatologist Francesca Fusco, MD, said there is no "golden rule" for the amount of times you should wash your hair a week. "If a person is oily, it's fine to wash it every day. If they are dry, it's fine to wash it once a week, but once a week at least for hygienic purposes. Individuals with dandruff should shampoo at least twice a week using an antidandruff shampoo."
