Hair Loss (Alopecia): Causes, Symptoms, and Treatments
Hair loss, also known as alopecia, affects a significant portion of the male population, with approximately 60% of men experiencing it during their lifetime. Male pattern baldness is the most common form of hair loss in men, often beginning as early as their 20s. Discover the causes, types, and effective treatments for hair loss below.
What Is Male Pattern Baldness?
Male pattern baldness, medically known as androgenic alopecia, accounts for 95% of hair loss cases in men. This hereditary condition is caused by sensitivity to the hormone dihydrotestosterone (DHT), which affects the hair follicles, causing them to shrink over time. This process leads to thinner and shorter hair, eventually stopping growth altogether.
