Chemical peels really don't cause any hair loss at the hairline and they should be done into the hairline to blend the exfoliating skin so there isn't a demarcation later. Sincerely,David Hansen,MD
In general, facial peels should not interfere with hair growth. The hair follicle originate deep under the skin, and the peels act on the superficial layers of the skin. There may be a few follicles that are affected mechanically (the rubbing of the skin) but not necessarily chemically.
