HOW MEN’S HAIR COMPLEX WORKS
Prevent hair loss.
Regrow hair. Finasteride inhibits 5-alpha reductase, an enzyme that converts testosterone into DHT, the hormone responsible for shrinking hair follicles in male pattern baldness. Minoxidil may improve blood flow to the scalp and support the growth phase of the hair cycle. Biotin supports healthy hair, and deficiency is linked to hair thinning.
Blocks DHT
Finasteride inhibits the 5-alpha reductase enzyme, reducing the DHT that binds to scalp follicles and shrinks them.
Slows follicle miniaturization
Follicles that were shrinking can stabilize or even partially recover, reducing the progression of hair loss over time.
Extends growth
Minoxidil helps hair follicles stay in their active growth phase longer, reducing shedding and increasing hair density.
