What is finasteride?
Finasteride is an oral prescription medication that blocks the conversion of testosterone to dihydrotestosterone (DHT), a hormone linked to hair follicle miniaturization in male pattern baldness.
It is FDA-approved for treating androgenetic alopecia in men and can slow or even reverse hair loss in some individuals by reducing scalp DHT levels. Side effects are possible and should be reviewed with a physician.
Red light therapy is often used alongside finasteride to provide a synergistic effect — reducing DHT’s damage while enhancing follicular regeneration and cellular energy metabolism.
