I used Schwarzkopf Red hair dye, and only got through half the bottle. Can i re-use it?

It doesn't look gone off or anything, but the bottle HAS expanded a lot where the mixture has been allowed to ferment.


Anybody know if you can re-use this stuff? xI used Schwarzkopf Red hair dye, and only got through half the bottle. Can i re-use it?
No.


As you leave it, it develops more and you can't use it.I used Schwarzkopf Red hair dye, and only got through half the bottle. Can i re-use it?
It depends how long it has been left unused for


I wouldnt reccomend using it if its been longer than a week, otherwise, it should be ok
No. Once it's opened, after a little bit, it looses it potency. So it wouldn't work again. :/
