The hair follicle that produces tightly curled hair is typically which shape?

The shape of the hair follicle plays a significant role in determining the texture and curl pattern of hair. Tightly curled hair is typically associated with an elliptical or oval-shaped follicle. This shape allows the hair to grow in a way that creates a twist or curl as it emerges from the scalp. The curvature is a direct result of the elliptical follicle, which causes the hair shaft to bend as it grows.

In contrast, round follicles produce straight hair because they allow for a uniform growth pattern, while square-shaped follicles are often linked to wiry or coarse hair. Wavy hair is also associated with follicles that are somewhat more oval but not as pronounced as those producing tightly curled hair. Understanding the link between follicle shape and hair type is essential for effective hair removal and treatment strategies.
