hair caused allergic reaction [SEP] as soon as i installed this hair my scalp was super itchy crazy itchy i was confused because this has never happened before and just thought maybe i braided too tight fast forward to the next week the scalp itch turned into hives i had never experienced this before and i do not have sensitive skin i got some advice from other black women to rinse this hair with apple cider vinegar i tried it and the hives are finally gone after suffering for two weeks the acv solved the problem however this is ridiculous the manufacturers of braiding hair knows we put this in our hair and they shouldn t use chemicals not safe for wearing or put a disclaimer to use acv on something we actually put close to our bodies it s insane do better
