I believe witch hazel should get it right out

Oil olive

Talk about a deja vu moment, but for once not an Aura. I just saw this exact question today in another group. I always say to find some T-Gel shampoo. It's really strong, and is used for adults who have severe dandruff. If you just rub it into the glue areas it comes off. I keep a bottle for when gum doesnt come out of SOME kids' hair. My kids hardly ever chew gum, but it gets there in some accident or another. Or in mine.

Try mayo to get the glue out. Another couple would be acetone or witch hazel. Make sure u scrub it real well. It may take awhile.
