One active ingredient stops your body from converting testosterone into DHT, the hormone that tells your hair follicles to give up (DHT is largely unnecessary for men during adulthood). The other ingredient is an antihypertensive vasodilator. It works by stimulating the hair into a ‘growth phase’.

This medication improves the delivery of vital nutrients to the follicles, while also blocking the enzyme that converts testosterone into dihydrotestosterone (DHT) – a hormone that stops hair growth.
