Redo Monster High/Barbie Hair without Heat?

Since someone on the Animo Toys app wanted to use the same method I used with the Kanekalon wig of my Pullip to redo her Mattel dolls curls and I wasn't sure if it works I tried it on 3 different Monster High dolls.

Well first, it really works, but the result of every doll is very different. It really depends on how well-curled the doll was before. 

First I tried it on Vandala. 

Before: 

And after: 

Her hair isn't that frizzy anymore but as you can see she hasn't really the curly curls. She got little waves, but I think it fits her kinda slimy pirate style. 

Secondly I tried it on Viperine.

Before: 

After:

I think it turned out really well if you consider it's completely made without heat. Those aren't really the most curly curls in the world, but it looks definitely better than before! 

At last, here is how River turned out. 

Before: 

After: 

Well since her hair isn't naturally curly I think it's better to use the popular boiling method here and just give her completely straight hair.
