Curly hair is most likely to frizz in humid conditions due to its structure and the way moisture interacts with the hair. Curly hair typically has more texture and is often more porous compared to straight hair. This porosity allows the hair to absorb moisture from the humid air more readily, which can lead to the cuticle layer of the hair lifting and causing frizz.

In humid conditions, the hydrogen bonds in the hair can break and re-form with the added moisture, disrupting the curl pattern. This results in a frizzy appearance as the curls try to absorb the humidity, leading to a lack of definition and smoothness. Therefore, those with curly hair often focus on using products that provide moisture and define curls while also seeking to control frizz caused by humidity.

Straight hair generally has a smoother cuticle and is less likely to absorb moisture in the same way, while wavy hair may be affected by humidity as well but not to the same extent as curly hair. Fine hair can certainly frizz, but it typically isn't as pronounced as in curly textures.
