Reply To: are girls allowed to dye their hair?

yitaynignwut: That may be (I can’t look it up right now) but one should still ask a sheilah and not make assumptions. We don’t necessarily posken by the Shulchan Aruch (especially Ashkenazim), and I am pretty sure that someone I know had to take the dye out of her hair before going to the Mikvah.
