Male hair loss is usually caused by genetics (Androgenetic Alopecia or Male Pattern Baldness) and more specifically, the conversion of the male hormone testosterone to Dihydrotestosterone – DHT. DHT decreases blood flow to the hair follicle causing the hair strands to progressively “miniaturize”, meaning the hair becomes thinner and thinner. Over time, the follicles can become dormant, or no longer productive, and no hair will grow from the follicle.
Male-pattern hair loss can result in a receding hair line and/or bald patches, mainly on the top and crown of the scalp. As men age, their hairline matures and for some men this is the beginning stages of Male Pattern Baldness. According to the Norwood Scale, a man’s hair loss can progress in 7 different stages, with the first stage starting as early as 16 years of age.
