My daughter has a couple of American Girl dolls with beautiful curls. Unfortunately even with gentle play, their hair becomes a mess. Every few weeks or whenever I notice it, I will take them aside and fix their hair.
It seems a lot of moms have the same problem with their daughter’s dolls but might not know how to fix it.
This is the way I fix Caroline’s hair also Saige and Kanani too;
First I separate small sections and brush each one straight. Next I curl the hair around my finger and let it go. I repeat with each section all the way around. I use the American Girl hair brush.
Their hair comes out very nice. It may not be factory or salon exact but it does look close and certainly a lot better.
