A quote from Jonathan Colombini, L'Oréal Paris creative director of style ...
Using hair dye after its expiration date is not recommended. While it might still work, the effectiveness, color, and safety cannot be guaranteed. The chemical components may degrade over time, potentially leading to uneven color results or an increased risk of allergic reactions.
According to manufacturers, unopened hair dye doesn't expire. They caution, however, that hair dye has a shelf life of about 3 years. After that period of time, hair dye may not work effectively. There's no evidence that old hair dye is dangerous to use.
Yes, hair color developer can go bad over time. Typically, unopened developer can last for about 3 years if stored properly in a cool, dark place. However, once opened, it's best to use it within 1 to 2 years.
Any hair color that utilizes a developer should be used within 24 hours of being mixed - ideally it should be used within 2 hours of being mixed.
Using old or expired hair dye can lead to funky colors and potential scalp irritation or allergic reactions. 🚫 Refrigerating the mix won't save the day either – it might actually decrease its effectiveness over time and still be unsafe for later use.
On most heads of hair, that would mean getting a good 6-8 weeks between touch-ups – but sometimes, even with permanent dye, colour fade can happen within a few weeks. Why does this happen? Typically, hair dyes are water soluble. When you wash your hair, the dye molecules simply dissolve and your new colour rinses away.

Permanent hair colors technically last until the color grows out, or until you recolor your client's hair – but they can fade over time. It may take anywhere between 6-12 weeks for the fading to be visible. But, of course, this all depends on the hair type and color products you're working with.
Hainla said that using expired hair dye can have negative effects. "After some time, hair dye can form chemicals harmful to your skin and hair, which can cause irritation or an allergic reaction," she explained.
Does Hair Dye Expire after Opening it? Yes, because once the hair dye is opened, it is exposed to sunlight, air, and moisture, which causes it to oxidize quickly. The more it oxidizes, the shorter its shelf life becomes. That is why manufacturers recommend using opened, unmixed dye within 6 weeks.

Longevity of color
However, it's important to consider other factors, such as your hair type and condition, desired result, application method, and cost, before making a decision on whether to choose salon hair color or box dye. Salon hair color is often more long-lasting than box dye.
The more porous your hair is – that is, the drier it feels and the more split ends it has - the quicker your color fades. So, it's definitely worth using a conditioner every time you wash your hair and, if you can squeeze it in, a hair mask (or a deep conditioning treatment) once a week.
