For those genetically predisposed to hair loss, DHT dwarfs the hair follicle, which causes the scalp hair to regress to a vellus state which renders the hair virtually nonexistent.
Vellus hair is the term used to identify the short hairs found all over the body except the palms, soles, and the underside of the fingers.
In general, the growth transition begins with large, thick healthy hair, then progresses to thinner, shorter, indeterminate hairs, and finally, short, nonpigmented vellus hairs cover the area sporadically.
