How does humidity affect curly hair?

Humidity has a significant impact on curly hair, primarily causing frizz and loss of curl definition. When the air is humid, moisture is absorbed by the hair strands. Curly hair, which is already more porous and often drier than straight hair, tends to absorb this excess moisture unevenly. This absorption can lead to the cuticle layers of the hair lifting, which disrupts the natural curl pattern and creates frizz.

As the curls become frizzier, the defined spirals that are typical of healthy curly hair can become less distinguishable. Instead of having clearly defined curls, the hair can appear puffy and messy due to the frizz. Therefore, the interaction between humidity and curly hair illustrates the challenges individuals with curly hair often face, highlighting the need for products and techniques specifically designed to manage and define curls in humid conditions.
