Baldness; why common in men?

By on April 4, 2013 in Health with 0 Comments

It’s strange to notice that most men eventually lose all of their hair with time. Baldness, technically known as alopecia, is the incomplete or total loss of hair which is known to be more common in men than in women. Before disclosing the reason why men become easy victims of baldness, let us first see the forms and patterns of baldness.

Forms of baldness:

Alopecia areata: Lack of hair in patchy form.

Alopecia totalis: Lack of hair from entire head.

Alopecia universalis: Lack of hair from head as well as the whole body.

Pattern of baldness:

The two patterns of baldness are the male pattern baldness and the female pattern baldness. Out of the two, you must’ve guessed which one is more common. Yes, you’re right! Male pattern hair loss is most common. It is described as the receding of hair from the sides of the forehead resulting in hair covering the head from the sides and back while the rest of the scalp is hairless.

But why men?

Well, there is a one-word answer to that. That is, testosterone. How? Research reveals that this male sex hormone transforms into a much strong hormone, DHT (dihydrotestosterone). DHT possesses different metabolic functions in the body. In some men, hair follicles are sensitive to dihydrotestosterone due some genetic or unknown cause. This results in hair thinning and ultimately hair fall.

It is said that out of 7 people, 4 of them have a fair chance of inheriting the gene responsible for baldness.

While various other factors may be responsible for loss of hair, DHT sensitization is the most precise reason of why baldness is predominant in men.
