There are some of you who also have Marie Grace as a modern doll in your collection. Some have inquired on "how" to straighten the waves from the braids and the CURLS from the tendrils. Here is how I straightened my doll's hair.
First I took her hair down and wet the sides completely. Hair must be soaking wet, towel dried and brushed into sections.
I used a hair straightening iron on the lowest setting.
You can see here that the hair in front is still wavy.
After it dried, I repeated the process making sure the small front sections were very wet. You may see steam as you do this, don't worry it's just the water evaporating not the hair burning.
This is her hair after the second treatment. I made sure to use braid spray this time then allowed it to air dry.
It is straight enough for me at this point and over time it will continue to relax with each brushing using braid spray in front.
Those of you afraid to use a hair straightening iron can try the hot water treatment. Be sure to section off the wavy hair and tie the back of the hair out of the way. You can dip her hair in one side at a time. Good luck!
