Have you ever wondered why some people have curly hair while others have straight hair? The answer lies in our genetics. Our hair type is determined by our DNA, which controls the shape and texture of our hair. In this article, we will explore why some people have curly hair and others have straight hair, and how to take care of both hair types.
What Causes Curly Hair?
Curly hair is caused by a genetic mutation in the hair follicle. The shape of the hair follicle is what determines whether the hair is curly or straight. In curly hair, the follicle is oval-shaped, which causes the hair to grow in a spiral shape. The more oval the follicle, the curlier the hair will be.
What Causes Straight Hair?
Straight hair is caused by a round hair follicle. The hair grows straight out of the follicle, without any curl or wave. Straight hair is the most common hair type, and it is found in people of all ethnicities.
Can Hair Texture Change Over Time?
Yes, hair texture can change over time. Hormonal changes, aging, and chemical treatments can all affect the texture of our hair. For example, women may experience changes in hair texture during pregnancy or menopause. Chemical treatments such as perms, relaxers, and hair dyes can also change the texture of our hair.
