What are the Effects of humidity on the hair structure and resulting style?

Humidity can significantly affect the hair structure and style by causing the hair shaft to swell and absorb moisture, leading to frizz and curl. High humidity levels can disrupt the hydrogen bonds in the hair, making it harder to maintain straight styles and resulting in a more voluminous, unpredictable appearance. Additionally, hair products may lose their effectiveness in high humidity, causing styles to fall flat or become unmanageable. Overall, humidity can challenge the integrity of hairstyles and influence their durability throughout the day.
