What is “shelf life?” Shelf life is how long a product can sit on a shelf before it goes bad. You are able to store an unopened hair color or highlights bottle for up to six months after it's made.
How do I maintain my color‘s shelf life? Simply keep your bottle in a cool, dry place, out of direct sunlight and extreme temperatures. We do not recommend saving or splitting any leftover hair color for later applications. That‘s because the moment you open your hair color, it will begin to oxidize. If not used immediately, you likely won't get the color result you'd hoped for.
