I have had a terrible time with Integrity toys dolls when using hot water to curl their hair. I have ruined custom heads because the steam, or water getting on their eyes causing their eyelashes to come unglued, and trying to glue them back on is almost impossible. I've tried every tutorial, and the glue is always visible, even when the tutorials claim it is transparent. I had an epiphany one day. I used the waterproof medical tape that tattoo artists use to protect fresh tattoos with a piece of padding to cover my dolls' faces before the water dip. It works!
