Humidity has a significant impact on styling products primarily because it affects the moisture content in the environment. When humidity levels rise, the air contains more water vapor, which can interact with the hair and styling products applied.

In high humidity, hair tends to absorb moisture from the air, leading to a change in its structure. This can result in frizz, as the hair shafts swell and become more porous. Additionally, many styling products are designed to create a barrier or hold the hair in place, but this barrier can be undermined by the added moisture from the humidity. As a result, the hold provided by these products may diminish, making it difficult for them to maintain the intended style throughout the day.

While some products might claim to combat humidity, the general effect of high humidity on hair is to cause frizz and reduce the effectiveness of the styling product. Therefore, recognizing this relationship is critical for hairstylists when recommending products and styles to clients, especially in regions with high humidity conditions.
