Male pattern hair loss is balding amongst men. It’s not always easy to identify at first, but early signs include a receding hairline, where hair starts to disappear at the temples of your head, producing a hairline that’s shaped like an ‘M’.
Another sign of it is crown hair loss, where your hair begins to thin at the crown (just off the top of your head, or the vertex, if you like to be academic). The thinning here leaves a bald spot.
In the areas where your hair is getting thinner, you may also notice that individual strands of hair are more fragile and brittle, and they don’t grow as quickly as hair in areas that are less impacted.
If you find that you’re losing a lot of hair after you’ve showered, on a towel or on a comb, this can point towards male pattern hair loss. And if the hair on the sides or the back of your head is not affected, but you’re losing hair on top of your head, this can be an early indication of male pattern hair loss too. This is because hair on the sides and back of your head is not as sensitive to the hormone DHT.
With male pattern hair loss, some men are more sensitive than others to DHT, or dihydrotestosterone, which is a type of testosterone in the body. This sensitivity causes hair follicles to shrink, and stops men from growing new hair. It also reduces the lifespan of hair follicles, meaning that you lose hair more often, and at a faster rate.
So you lose hair more quickly, but the hair is also replaced more slowly, and it doesn’t grow back as rapidly.
