Stores probably had it on the shelf for a long time too.
It usually won'texpire as soon as food (it's all chemical anyway) , but check the expiration date.
But if you already mix it together, then you should use it right then.

ok... it doesnt matter how long after you buy it that you use it, unless you have mixed it. If you mix the developer and the toner, you need to use it within an hour.. after that, its void. not only can it explode, but it wont do you any good, because the chemicals stop working. If you havent opened the box.. you can keep it for a long time.

As long as you haven't mixed it already, yes, it's fine to sit there for a while. I do it all the time, cuz I'm a procrastinator. In fact, I'm sitting here with dye in my hair at this very moment...waiting for the shower to be free. =)

The color will be fine as long as you've kept it closed and you haven't mixed it at all.

As long as it is unopened it is safe. I wouldn't keep it for more than 2 months however.
