Heat sealing with hair and/or eyes

I have a couple dolls I would like to reborn but they already have eyes and i don’t want to remove them.
Also on hair. Can you heat seal once hair is been rooted, using natural hair of course?

Depending on the quality of the eyes they should be okay with the heat. Keep it at 260 for a longer time maybe? The hair yes, I’ve baked with hair if I’ve forgotten to add or want to touch up my paint. Just dampen a wash cloth and cover the hair HTH’s
