Which type of hair texture is most prone to frizz?

Curly hair is most prone to frizz due to its unique structure and the way it interacts with moisture in the environment. The natural curl pattern creates uneven surfaces along the hair shaft, making it more susceptible to humidity. When the air is humid, moisture can infiltrate the hair, causing the cuticle (the outer layer of the hair) to swell and lift, resulting in a frizzy appearance.

Curly hair often has a drier texture compared to other hair types since the natural oils produced by the scalp do not travel as smoothly down the twisted strands of hair. This lack of moisture can lead to increased porosity, where the hair absorbs water easily but also loses it just as quickly, contributing further to frizz.

In contrast, straight hair has a smooth cuticle that helps it resist frizz better, while wavy hair has a more balanced structure that can manage humidity effectively. Kinky hair, although it can also experience frizz, typically has a denser texture and may hold its shape better. Therefore, curly hair stands out as the most frizz-prone texture.
