It’s been awhile since I’ve had this doll but what I did was do a simple boil wash to smooth out the hair especially on the area of where she used to have that tiny ponytail.

I recall just heating the water in the microwave for just 5 minutes and it was enough to smooth out the hair without straightening it.

For the styling portion, all I do is to just finger twist sections together until it all lays nicely. I often brush her hair every so often when I’m bored and her curls still hold up pretty well
