Hair thinning occurs when dihydrotestosterone (DHT) binds to androgen receptors in hair follicles. This restricts blood supply, shrinking the follicle (miniaturisation) until the hair grows thin, weak, and eventually stops sprouting.
Research published in the International Journal of Dermatology demonstrated that topical caffeine counteracts testosterone-induced follicle suppression, stimulating hair shaft elongation and extending the anagen (growth) phase.
