A little while ago I put curlers in Hailey's hair.Though she has straight hair, it worked!
So, to do this, use 12-15 curlers. Mist your doll's hair and take little sections. I left the curler's in for 4-5 days. I misted the hair every 12 hours. The hair was curled because it dried in a curled position. I suggest putting the curlers in during the middle of the week when you may not use your doll as much and taking them out over in the weekend when you may have more time to style it or do a photoshoot.

The curled kind of flipped up here
She accidentally toppled over, but look at her curls!
The curled only lasted a day or two but they were absolutely gorgeous on her. Please send me a picture of your doll if you try out this method! I would LOVE to see how it works on other dolls.
