How does humidity affect hair styling?

Humidity has a significant impact on hair styling, primarily by causing frizz and affecting how long styles maintain their intended shape. When the air is humid, it contains a higher level of moisture. This surrounding moisture can be absorbed by the hair, especially in strands that are porous or damaged. As hair absorbs this moisture, it can swell and disrupt the alignment of the hair cuticle, leading to frizz.

Frizz occurs when the outer layer of the hair (the cuticle) lifts and allows moisture to penetrate the hair shaft, making the hair look uncontrolled and less smooth. Consequently, styles that rely on smoothness and sleekness may not hold up well in humid conditions, resulting in a less polished look. Therefore, understanding the effects of humidity is essential for hairstylists to choose the right products and techniques that can help mitigate these effects on various hair types.

This highlights the importance of considering environmental factors, like humidity, in hair styling, and why many stylists opt for humidity-resistant products or specific styling techniques when working with clients.
