How do you wave hair with no iron?

To wave your hair with out iron? First, I am assuming you have straight hair. You should get y our medium wet, but not sopping. A good idea is to blot your hair with a towel or tie it up for a little while depending on the thickness of your hair. Then, make thick braids (3 inches). Leave them be over night. When your wake up, be very carefull when you unbraid. Slideoff the hair band (do not use rubberbands), then work your fingers through the braides. If they are still wet, witch they probaly be if you have thick hair, do not blow dry. Do not brush them or comb them or put gel in them. You can put a small amount of spray, if you like.
