What happen to hair dye mixes if you leave them out without using it?

Question

Will it explode or rise?

Answer 1

Rise yes... explode??? I have come back to some mixed in a color bottle and it was ooozzing out the top... they color oxzidates and is not any good after a hour or 2 hours tops... hope this helps

Answer 2

AHHHHHH NO, it will only oxidize and be of no use to you, only bleach swells in the bowl. and only bread rises

Answer 3

I left some reddish auburn coloured dye, it just turned really dark - almost black. Didnt explode or anything.... wouldnt like to clean that up! Haha
