Describe the effects of humidity on the hair structure and resulting style?

Humidity can significantly impact hair structure and style by affecting the moisture balance within the hair strands. High humidity levels lead to increased moisture absorption, causing hair to swell and become frizzy or lose its shape, especially in curly or wavy hair types. This can result in a lack of definition and control, making it challenging to maintain certain hairstyles. Conversely, low humidity can lead to dryness, causing hair to become brittle and less manageable.
