Caffeine Shampoo

Topical caffeine to counter DHT at the follicle

A shampoo containing at least 0.2% caffeine, massaged into the scalp and left for 2 minutes before rinsing. Caffeine applied topically penetrates the hair follicle rapidly and has been shown in vitro to counteract testosterone-driven follicle suppression, extend the anagen phase, and stimulate hair shaft elongation. Clinical trials show measurable increases in hair count with daily use over 6 months.
