Humidity Changes the Length of Human Hair

The length of human hair does change depending on the level of relative humidity present in the air. When the humidity increases, the length of the hair is increased. As the humidity goes down, the length of the hair shortens. .

Humidity and Frizzy Hair

As hair gets longer in air with a high percentage of relative humidity, the hair absorbs some of the moisture, causing the hair strand to swell and become frizzy. Alternately, when the air is very dry, the hair shrinks, also causing excess frizz to appear.

Humidity and Curly Hair

Curly hair, which has a coarser texture than straight hair, absorbs more moisture from the air. On days with high humidity, curls will be more enhanced, even though they may have slightly more frizz.

Haircuts to Control the Effects of Humidity on Human Hair

Certain hair cuts can help reduce the impact of humidity on human hair. Layered haircuts, which are best for fine and limp hair, will add dimension and volume, even when humidity is high. Choosing a haircut that works with the natural texture of the hair will help reduce the amount of frizz that occurs when humidity is high.

Controlling Frizz With Styling Products

Because the effects of humidity on human hair are problematic for so many people, hair products are available to help lessen the effects. Smoothing serums, styling creams, special conditioners, and pomades can all help reduce the frizz associated with humidity.
