This is a bit random but I bet one of you will know the answer. I have a box of Garnier Nutrisse hair dye i was planning on using tomorrow. The snappy lid on the developer has broken off in the drawer (the white stuff not the coloured) and there has been a small leak. My question is - will the stuff still be all right to use as in effective and safe or will it have had some peculiar chemical reaction of which I am unaware? Not the end of the world if I have to chuck it as i have another but a waste of a fiver. Thanks for reading peeps.
