safe to use heat on sunshine pony hair?

[faespirit]

I have sunshine pony seaflower. her hair is fine except for the pink stripes which are super frizzy at the ends and it bothers me bc I can't display her. I was wondering if it was safe to use heat to defrizz it. would that ruin the color changing properties of her hair? I'm not even sure if it still changes color tbh

Heat can indeed ruin these ponies' hair. If you are very patient and careful and use a very low heat setting, you may be able to fix some of the hair, however, these ponies are notorious for frizzing up. I wouldn't try to push it too hard for fear of melting her hair. Try to avoid boiling temps.
