This is why I used petroleum jellly on the mane prior to the peroxide bath...it kept the hair from fading at all! A little smear on the symbols to protect them might be a good idea, too, if you're afraid of them being damaged. I've not had a problem with it affecting paint or sparkles or anything, either, but no guarantees
That is an awesome tip! I was thinking of testing on a baity Majesty but her hair color kept me from trying, thank you!
