How Bad Is Your Hair Loss? A Complete Guide to the Norwood Scale and Male Pattern Baldness Stages
What is Male Pattern Baldness?
Male pattern baldness, also known as androgenetic alopecia, is the most common cause of hair loss in men (approximately 80%). It is a progressive hair disorder that is believed to be mainly due to genetic predisposition and hormonal factors, particularly the sensitivity of hair follicles to dihydrotestosterone (DHT), a byproduct of testosterone. The condition is characterised by a receding hairline and thinning at the vertex and mid-scalp region. The condition can start as early as the late teens or twenties and becomes increasingly common with age. Over time, affected hair follicles gradually shrink, producing finer, shorter hairs until they eventually stop growing hair altogether. The extent and progression of hair loss are commonly assessed using the Norwood Scale, which classifies the various stages of male pattern baldness and helps guide appropriate treatment options.
