Male pattern baldness is the most common type of hair loss in men.
Male pattern baldness is related to your genes and male sex hormones. It usually follows a pattern of receding hairline and hair thinning on the crown, and is caused by hormones and genetic predisposition.
Each strand of hair you have sits in a tiny hole (cavity) in the skin called a follicle. Baldness in general occurs when the hair follicle shrinks over time, resulting in shorter and finer hair. Eventually, the follicle does not grow a new hair. However, the follicles remain alive, which suggest that it's possible to grow new hair.
The typical pattern of male baldness begins at the hairline. The hairline gradually moves backward (recedes) and forms an "M" shape. Eventually the hair becomes finer, shorter, and thinner, and creates a U-shaped (or horseshoe) pattern of hair around the sides of the head.
Male pattern baldness does not indicate a medical disorder, but it may affect self-esteem or cause anxiety. The hair loss is usually permanent.
