HAIR HELPERS

Mason Pearson filling up a bit too quickly? You're not alone. "I used to treat about three patients a month for hair loss, and now it's roughly three per day," says NYC-based dermatologist Macrene Alexiades-Armenakas, MD, who attributes the "astounding increase" of hair loss to stress-induced testosterone production, which causes hair follicles to slow down.

Double Up: To jump-start growth, Alexiades often suggests combining her "mainstay" treatment, Rogaine (minoxidil), with a topical prescription of testosterone-regulating spironolactone (like many prescription therapies, the combo is not for women trying to get pregnant, or who are pregnant or nursing). Miami- and New York–based dermatologist Fredric Brandt, MD, sends patients home with biotin supplements (which help the body metabolize amino acids and protein, the basic building blocks of hair), plus a prescription for a pharmacist-blended compound of eyelash-boosting Latisse (which many derms have found also stimulates hair growth on the scalp) and liquid Retin-A.
