What is Male Pattern Baldness (MPB)?
Male pattern baldness, also known as MPB or androgenetic alopecia, is the most common cause of hair loss in men. MPB is characterized by a thinning crown and receding hairline. The condition typically progresses until only a “horseshoe” rim of hair remains. MPB is caused by a genetic sensitivity to a hormone known as dihydrotestosterone that causes hair follicles to shrink and stop producing hair.
