Will less shampooing help with oily hair?
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.

Dandruff, no matter how severs, cannot cause hair loss.
Dandruff cannot cause hair loss.
While claims abound that dandruff causes hair loss and balding, there is no scientific evidence that it does. Though unsightly, dandruff is normal. Almost everyone experiences it at some point in his or her life, though it afflicts men more often. (For more on that, check out a recent post of mine titled, “The Truth About Men and Dandruff.“)
If you have dandruff and are experiencing patchy hair loss, then it could be any number of other hair loss diseases, including male pattern hair loss or alopecia aerata. See your dermatologist who can help you.
