Although great care is taken with all the products we buy, for you to have your fun with, be aware that sometimes allergic reactions can happen. Though this maybe rare, it can still happen.
We always suggest a 24 - 48 hour patch test to test for reactivity on our pigments. Even though these colour pigments are used on a industrial scale in the cosmetic industry world wide. There will be some people who will react to any foreign body on the epidermis nail and hair area, for these people we suggest increasing the reactivity test to 72 hours to eliminate any chance of a reaction to these ingredients.
