Pyrithione Zinc

Pyrithione zinc, an ingredient in some anti-dandruff shampoos, has been shown to improve hair growth in men with Hamilton-Norwood Type III or Type V hair loss. (see Androgenetic Alopecia). The improvement in hair count (hairs per square centimeter) was modest but sustained over a 26-week randomized clinical trial using a 1% solution of pyrithione zinc in an anti-dandruff shampoo. The finding is being followed up by further investigations. Pyrithione zinc or anti-dandruff shampoos have not been approved by the FDA as hair loss treatments.
