How does humidity affect curly hair?

Humidity significantly impacts curly hair due to its interaction with moisture levels in the air. When humidity is high, the excess moisture can penetrate the hair shaft, disrupting the hair's natural curl pattern. This often leads to frizz, which is the result of the hair structure absorbing moisture unevenly.

Curly hair is particularly sensitive because it is composed of different curl patterns that can easily become unruly when affected by environmental factors like humidity. The absorption of moisture makes the hair swell, causing it to lose its defined shape and leading to a less polished appearance.

Additionally, the unique structure of curly hair makes it more prone to frizz, as the cuticle layer, which protects the hair shaft, may not lie as flat as it does in straight hair. This fact reinforces the tendency of curly hair to appear frizzy in humid conditions, making the choice about the effects of humidity on this hair type accurate.

In contrast, the other options do not represent the effects of humidity on curly hair correctly. While humidity might create temporary shine in some hair types, it generally leads to frizz in curls. It does not straight hair; rather, it disrupts the existing curl pattern, and while it might contribute to hair feeling damp or take longer
