What are the effects of humidity atmospheric moisture on blow-dried hair?

Humidity can significantly affect blow-dried hair by causing it to become frizzy and lose its smoothness. The moisture in the air can lead to the hair absorbing water, which disrupts the bonds that were set during the blow-drying process. This can result in a lack of volume and definition, making the hair appear limp and unmanageable. Additionally, high humidity can diminish the effectiveness of styling products, making it challenging to maintain a desired look.
