I need to add some stabilizer, and I have a jug of Instant Conditioner that's been sitting in the garage for three years since I first bought and used it. Does it get old? Is there anything wrong with using it now, or should I throw it out and buy a new jug?
I don't even remember what the liquid looked like when I used it last. Right now, after being shaken, it looks like a thick, opaque white liquid.
