How often should I wash my oily hair if I have acne?

You should wash your oily hair every day if you have acne. Acne is caused by too much sebum (oil) and dead skin cells clogging pores. Washing your hair with a mild, oil-free shampoo can help remove excess oil around your face. Shampooing your hair can help remove the buildup of oil and help prevent acne breakouts. Look for hair products that are non-acnegenic or non-comedogenic. These products won't clog your pores and are less likely to cause pimples. The ingredients in products vary, so choose one that is appropriate for your skin type and condition.
