不知道从什么时候开始,原本属于中年人的苦恼,已经成为了当代年轻人的烦恼——脱发。这届年轻人为了发际线有多努力?有没有科学方法可以预先判断自己成为秃头的概率呢?今天就从科学角度来看一下。

You've probably heard people say that if your mother's father was bald you're more likely lose those beautiful locks of hair down the road.

But what truth is there to this?

It turns out that one of the major contributors to hair loss is sex linked.

Humans have forty-six chromosomes of DNA, of which two help determine your sex, the "X" and the "Y" chromosome.

If you're a female you have two "X" chromosomes, but if you're a male you have an "X" and a "Y" chromosome.

Studies show that the most influential hair-loss gene is located on the "X" chromosome only.

What does this mean?

Well if you're a male you get an "X" chromosome from your mother, but must receive a "Y" chromosome from your father.

Because if you got your father's "X" chromosome you would be a female.

So if one of your mothers "X" chromosomes has this hair loss gene you have a 50/50 chance of getting it from her.
