Minoxidil stimulates longer anagen phases and shorter telogen phases as well as trigger growth in dormant follicles.

Androgenetic alopecia is a hereditary condition that causes hair loss in men. Males can suffer from hair loss and early as their 20’s. In fact by the age of 50, 50% of males will experience hair loss. Normal hair growth takes place in three phases in the follicle: anagen, catagen and telogen phases. In the anagen phase, the cells of the hair matrix responsible for growth actively multiply and are pushed upwards to form the hair shaft. After two to six years the follicles transitions into the catagen phase. In this phase hair growth stops. The base of the hair shaft keratinizes and moved upwards away from the papillary blood supply. Lastly, the follicle enters the telogen phase where the hair transforms into club hairs and migrates up the hair sheath. With androgenetic alopecia, the anagen phase is shorter and the telogen phase is longer. This results in shallower follicles and thinner hair over time.
