What causes some hair to be straight and some to be curly?

To better understand the differences between straight and curly hair, we need to take a look at what is inside your hair follicle. Follicles that are straight will result in straight hair fibers. Curved follicles (even a slight curve) and you’ll likely have curly hair.

Did you know that researchers believe that the shape of your hair happens during the development of the embryo?! They don’t know why this occurs, but those that have S shaped hair will have a follicle that has two bends in it. This type of shape is permanent and you will most likely have curly hair throughout your lifetime.

Genetics also come into play in the production of curly hair. If you have family members with curls, chances are you will as well. A protein known as trichohyalin is responsible for this.

Here’s a bit of trivia you can tell people: When a strand of hair is cross cut, it is very round but when curly hair is cross cut it will be more of an oval shape.
