How does humidity affect hairstyles?

Humidity significantly impacts hairstyles primarily by causing frizz and loss of hold. When humidity levels are high, moisture from the air can be absorbed by the hair cuticle. This absorption disrupts the hydrogen bonds in the hair, leading to swelling and the hair strands expanding. As a result, hair can take on an unruly appearance due to frizz, where the strands lift and separate instead of lying flat.

Additionally, styles that require a smooth finish, such as straightened or sleek looks, can easily lose their shape and hold in humid conditions. The moisture in the air compromises the effectiveness of styling products, which are meant to provide structure and longevity to hairstyles. Consequently, hair that may have initially been styled beautifully can quickly revert to a frizzy or unkempt state when humidity levels rise.

While humidity does not enhance shine or volume in a controlled manner, it mainly interferes with the hold and neat appearance of hair. Thus, understanding this effect of humidity is essential for hairdressers to choose appropriate products and techniques for their clients' hair on days with higher humidity levels.
