Caution use this Just for kids Caivel relaxer with caution

Ok I bought a just for kids Caivel hair relaxer which is for normal hair in a white and blue tub. Upon applying it on my niece's hair she started complaining about how much it was burning her scalp and after a few seconds her whole head started to burn I had to wash it off immediately. And while doing this my own hands started burning of the relaxer. The hair was still the same the relaxer did nothing except causing us great discomfort. The thing that made me buy the relaxer is that it says mild and gentle yet it's filled with really strong chemicals. Please mom's be cautious before using this product on your kids I would not recommend it
