Kirkland signature minoxidil

Minoxidil is an FDA-approved medication used topically or orally to stimulate hair growth and slow hair loss, primarily for hereditary male and female pattern baldness (androgenetic alopecia). It is widely available over-the-counter as a solution or foam under brand names like Rogaine and as a generic product. 

How It Works

While the exact mechanism is not fully understood, minoxidil is believed to work by: 

Increasing blood flow to the scalp, delivering more oxygen and nutrients to the hair follicles.

Prolonging the anagen (growth) phase of the hair cycle and shortening the telogen (resting/shedding) phase, leading to longer and thicker hair.

It is a prodrug, converted to its active form, minoxidil sulfate, by an enzyme in the hair follicles, which varies in activity among individuals
