Question: Why is my hair sometimes a lot curlier than normal?
Most people will notice a change in the hair when the humidity is high. Humidity causes the moisture in the air to rise, which results in even curlier hair than usual. You also might notice your hair is curlier if you change your shampoo and conditioning routine, or wash your hair more frequently. To keep your curls under control, try not to over shampoo your hair.
