How to make the great curls

I have straight, thick hair, as many people know, curlers do not hold longer than 2-3 hours, and it is not what you want to get.
There is a new solution of this problem! Great gorgeous curls can hold up to 5-6 hours and it is very simple!

1) You have to wet the hair with a little water.

2) Twist the hair into a knot and handle them with a hair iron.
