Here's how it works:
* Follicle Shape: The hair follicle, the small pocket in the skin where hair grows, has a unique shape. Round follicles produce straight hair, while oval follicles produce wavy or curly hair.
* Internal Structure: The internal structure of the hair shaft, which is made up of keratin proteins, also contributes to hair shape. Curvy follicles cause the hair shaft to grow in a curved pattern, resulting in waves or curls.
Other factors that can influence hair shape:
* Genetics: Your genes play a significant role in determining the shape of your hair follicles and, consequently, the texture of your hair.
* Hormones: Hormonal changes can affect hair texture, sometimes causing hair to become curlier or straighter.
* Hair Products: Styling products, such as relaxers or perms, can temporarily or permanently alter the shape of your hair.
So, while the shape of the hair follicle is the primary determinant of hair shape, other factors also contribute to its appearance.
