What exactly is DHT? Dihydrotestosterone (DHT) is an androgen hormone derived from testosterone through the enzyme 5-alpha-reductase.
While DHT plays an important role in male development, an excess of it in the scalp follicles becomes the leading cause of androgenetic alopecia, or pattern hair loss.
When DHT levels rise, it shrinks the hair follicles over time, leading to thinner strands, slower growth, and eventually, hair loss.
