Humidity significantly affects hairstyling primarily by influencing the moisture content in the hair. When the humidity levels are high, the hair tends to absorb moisture from the air, which can lead to an increase in the hair's natural curl pattern or volume. This moisture can cause hair strands to swell and lose their smoothness, resulting in frizz and making it difficult for certain styles to hold.

For instance, styles that rely on sleekness, such as straightened hair or defined curls, can become unruly as the hair's cuticle layer opens due to the moisture. This phenomenon occurs because the hydrogen bonds that have been altered during styling (e.g., with heat or chemical treatments) begin to reform in the presence of increased moisture, thereby reverting the hair closer to its natural state.

Therefore, recognizing how humidity interacts with hair texture and styling products can greatly assist hairstylists in managing client expectations and selecting the right products for desired outcomes under varying weather conditions.
