What is the effect of high humidity on natural hair?

High humidity has a significant impact on natural hair, primarily causing frizz and moisture imbalance. When the air is humid, it contains a higher amount of moisture, which can be absorbed by hair strands. Natural hair, often characterized by its texture and curl pattern, has a tendency to absorb moisture from the environment. This moisture can cause the hair to swell, leading to frizz as the cuticle lifts and separates.

Furthermore, while humidity can initially hydrate hair, it can disrupt the balance of moisture, making hair feel more dry or greasy depending on the individual's hair type and care regimen. This imbalance can make it challenging for individuals to maintain their desired hairstyle, as the natural oils and moisture can become unmanageable. Thus, the correct answer accurately reflects the physiological response of natural hair to high humidity levels.
