Why Does Humidity Cause Frizzy Hair? - Causes & Solutions

Humidity

Humidity is the amount of water vapor in the air. When the air is humid, it means that there is a lot of water vapor in the air. This water vapor can cause hair to swell and become frizzy. Frizzy hair is hair that is dry, damaged, or has a high porosity. When hair is frizzy, it is more difficult to style and can look unkempt.
