I get this question all the time from patients, particularly men. Here’s the truth about shampooing and oily hair:
No matter how frequently you shampoo, your scalp produces the same amount of oil. Cutting back on shampooing will have no effect on your sebaceous glands; genetics and hormones determine the amount of oil they produce. But it will cause dirt and oil to accumulate on your scalp and hair follicles, and could cause inflammation and irritation that might stunt hair growth. How often you wash your hair is a personal decision. Wash your hair with a moisturizing shampoo when you feel you need it, whether that’s daily or weekly. Or if you like making shampoo mohawks.
