What is heatdamage?

Heatdamage is damage to the curls due to applying direct heat.

Curls are very elastic and vulnerable, so when you apply direct heat, the chances that you damage "the elasticity" of the curls is really big. Heatdamage is a really common problem, because people often don't see the danger in it.

Once it's done, you can not go back and your hair will change forever, unless you cut it.
