I bought a bunch of 90's Barbies at a thrift store for kids to play with, but I did not try to wash and comb the tangled hair. If you even touch the hair it will tangle at once, and brushing it and combing it will cause damage and hair lose. So one of them I decided to comb out when wet and it really messed up my hand. The plastic brush got bent and my hand is killing me from trying to do that. The other dolls I am not even going to try to untangle because I will only ruin my hands and as soon as kids start to play them the hair will re tangle.
