How does high humidity generally affect hairstyles?

High humidity impacts hairstyles primarily by causing frizz and loss of style hold. When the air is humid, it contains a higher amount of moisture. Hair, being porous, tends to absorb this moisture from the environment. As the hair absorbs humidity, it swells and can lose its smoothness, leading to a frizzy appearance. Additionally, styles that rely on specific forms and holds, such as curls or straightened looks, can be compromised as the hair's texture changes in response to the moisture in the air.

This phenomenon is particularly noticeable for those with naturally curly or wavy hair, as the additional moisture can enhance their curl pattern but also make it less defined and more unpredictable. Consequently, achieving and maintaining a polished hairstyle becomes more challenging in humid conditions, which is why frizz and loss of style hold are commonly observed effects of high humidity on hair.
