If your grandparents or parents have thinning hair, even you will have thinning hair! I recommend that you don’t have to give up on the idea that it’s genetic, because there are ways to help.
How likely is thinning hair to be inherited?
It has been said that thinning hair as well as AGA is inherited. What is the probability of inheritance?
Men are greatly influenced by their maternal grandparents, and women by their paternal grandparents, but the probability is only about 25%. However, if both the father’s and mother’s side of the family have thinning hair, the probability of inheritance will exceed 30%.
Also, the probability is not the same if the parents are the same. The probability of having thinning hair varies even among siblings, so it is not 100% inherited and thinning hair.
Thinning hair was not just a DNA problem that was inherited!
When people think of heredity, they think it is all about genetic (DNA) influences. In fact, the influence of DNA is called congenital heredity.
Since congenital heredity cannot be changed, it has no small influence on thinning hair. However, during life after birth, we often have lifestyle habits similar to those of our parents, which is called acquired heredity.
These are things like food preferences, physical activity, smoking habits, and other lifestyle habits acquired while living with one’s parents. If it is an acquired inheritance, it can be improved with a little effort and a little correction of habits, so if you can prevent thinning hair, consider that this is the area where you can do so.
Learn about the probability of heredity and how lifestyle changes can prevent thinning hair.
As we have mentioned, it is not 100% certain whether genetics causes hair thinning. From here, we would like to introduce some measures to deal with acquired heredity.
- Acquired heredity can be improved
Acquired genetics can be improved if they are acquired as a habit of life. This is a recommended method for preventing and combating thinning hair, so please take a look back at your daily life by reviewing your diet, exercise, and smoking and drinking habits.
There are many causes of thinning hair, and many people have several of these causes mixed into their lives.
- There are ways to check if it is inherited.
There are ways to confirm whether thinning hair is inherited. This is mainly done as a test for AGA, and you can check for the activation of the enzyme 5-alpha-reductase with a blood test. This 5α-reductase combines with male hormones to become dihydrotestosterone, which worsens hair loss and thinning hair.
As mentioned above, we recommend that there are ways to address the genetic causes of thinning hair.
