How Is Hair Loss Related To Genes?

Are your beautiful locks of hair a big hit with the ladies? Do you take special care to maintain your hair? With all this time and energy that you pour into your appearance, are you ever plagued by a question: Are you going to have that hair all your life?

What are the chances of going bald? If your father’s bald, is there a chance that you will also lose that beautiful head of hair?

Let’s find out.

One of the major causes of hair loss is genetics, and it is sex-linked, so you should look at your maternal grandfather’s, hair rather than your father’s, to have some clue as to whether you are going to be bald in the future.

What causes Hair loss?

The most influential hair loss gene is located in the X chromosome. If you are a male, then you will have an XY chromosome – X from your mother and Y from your father.  Your mother has XX chromosomes, which she receives from her mother and father. So, if her father is bald, then he must have passed the X chromosome with the hair loss gene to your mother. That means that you would have a 50/50 chance of getting the X chromosome with the hair loss gene from your mother.

Checking Baldness


In other words, if your maternal grandpa is bald, then there is a 50% chance that you’re going to lose your hair in the future.

Although the major cause of hair loss is hereditary, the hair still sitting on your grandpa’s head does not necessarily get you off the hook for hair loss, as balding is dependent on other factors as well.

A number of studies have shown that hair loss genes can sometimes be transferred from the Y chromosome on your father’s side. Stress levels, age, exercise levels etc. can also play a part in causing hair loss.
