Mixed hair dye must be used within 1 hour. Mixed hair dye is dangerous to store, has no shelf life, and can't be used at a later date.
What's the longest you can leave hair dye in?
Color needs to stay on your hair a certain amount of time for it to penetrate the hair. The longer you keep it in the better to an extent. Never leave it on more then 30–40 minutes unless it's direct dye.
What happens if hair dye is left on too long?
"If you leave your color on for too long, there is potential for extra deposit of pigment to occur. You can't make your hair too light by leaving a tint color on too long (unless you're bleaching), but it can make your hair darker than intended," says Tardo.
Can I save mixed hair dye and use it later?
Left over product: can I keep it for next time? No, you cannot keep a mixture for a future application. Once the product mixture has been realised, you must immediately apply on your hair.
