Is thick hair genetic?

Yes, the thickness of hair is largely determined by genetics. Hair thickness is determined by the diameter of the individual hairs, which is determined by the genes that are inherited from the parents. Hair texture, on the other hand, is determined by the shape and size of the hair follicle, which is also determined by genetics. Therefore, if either or both of your parents had thick hair, then it is likely that you will also have thick hair.

What nationality does thick hair come from?

Thick hair can be found in a variety of nationalities and ethnicities. In general, it is more common in people from East Asian and South Asian backgrounds, but it can also be found in people from African and Middle Eastern backgrounds. Additionally, some people of European descent may also have thick hair.
