What is Male Pattern Baldness?
Male pattern baldness (also known as “androgenic alopecia”) is the most common form of hair loss in men, with it making up 95% of the reasons for the condition. Male pattern baldness is genetic and can be attributed to a hormone known as DHT, which likely affects how sensitive your hair follicles are.
When the hair follicles are sensitive, they shrink and the hair starts to become finer, thinner, and shorter. It begins taking longer and longer to grow back — until finally, no hairs grow back at all. Inflammation and reduction in the small blood vessels that supply the region near the hair follicles are also significant contributing factors.
The first signs of male pattern baldness typically start to show at the temples, with the hairline regressing slowly but steadily. After this, the hair of the crown begins to thin. Eventually, the bald spots from the temples and the crown meet in the middle, resulting in baldness at the top of the scalp. This leaves only a horseshoe-shaped rim of hair that goes around the ears and back of the head.
