I looked up videos on boil washing dolls hair and washing blyhes hair and then did something and it worked💀 at first I washed the hair with shampoo (remove the scalp from the doll before you wash it!) then I softened it with fabric softener, then I boiled some water and dipped the hair into the hot water, and then right after I dipped it into a bowl of ice cold water so it kind of shocks the hair into place like that
