Humidity plays a significant role in how hair behaves, particularly in relation to hairstyling. When the air is humid, it contains more moisture, which can lead to hair absorbing this moisture. This process, often referred to as "hygroscopy," causes the hair's cuticle to swell and can disrupt the hair's natural texture and style. As a result, hair often becomes frizzy and loses the intended sleekness or smoothness that may have been achieved through styling products or techniques.

In essence, the increased moisture in the air can lead to the hair strands curling and separating, thereby creating a frizzy appearance. This is particularly common for individuals with naturally curly or wavy hair, as the moisture in the environment can exacerbate their natural wave pattern, leading to an uncontrolled look. Thus, understanding how humidity impacts hair is crucial for hairstylists, as they can choose appropriate products and techniques to mitigate the effects of high humidity and maintain a client's desired style.
