Hair dye is a product that many people use to change the color of their hair. The dye can last for several weeks or even months in the bottle, but it will eventually start to fade. The length of time that the dye lasts in the bottle will depend on the type of dye and how it was stored.
If you’ve ever wondered how long that bottle of hair dye in your medicine cabinet has been sitting there, you’re not alone. Hair dye does have a shelf life, but it’s not always easy to determine how long it will last. Here’s a look at some of the factors that can affect the longevity of hair dye.
The first thing to consider is the type of hair dye you have. Permanent hair dye will last the longest, while semi-permanent and temporary dyes will start to degrade after a certain amount of time. If you’re not sure how old your hair dye is, it’s probably best to err on the side of caution and assume it’s nearing the end of its shelf life.
Another factor to consider is how the hair dye is stored. If it’s exposed to light or heat, it will degrade faster. So, if you’ve had that bottle of hair dye sitting in a sunny window, it’s probably not going to last as long as a bottle that’s been stored in a dark, cool place.
Finally, it’s worth noting that hair dye does have an expiration date. This is usually printed on the back of the bottle, and it’s generally about two years from the date of manufacture. After that, the hair dye may not work as well or may not work at all.
So, how long does hair dye last? It depends on a few factors, but generally speaking, it’s best to use it within two years of the manufacturing date. After that, you may not get the results you’re expecting.

Can You Use Leftover Hair Dye?
If you’ve dyed your hair and have leftover hair dye, you may be wondering if you can use it again. The answer is maybe. It depends on the type of hair dye you used and how long ago you used it.
If you used a semi-permanent or temporary hair dye, it’s probably fine to use it again. These types of hair dye don’t penetrate the hair shaft as deeply as permanent hair dye, so they don’t last as long. If it’s been a few weeks since you dyed your hair, you may be able to get away with using the leftover hair dye.
Just keep in mind that the color may not be as vibrant as it was the first time around.
If you used a permanent hair dye, you may be able to use it again, but it’s not recommended. Permanent hair dye contains ammonia, which helps open up the hair shaft so the color can penetrate.
This also means that the hair shaft is more vulnerable to damage. If you use permanent hair dye more than once, you run the risk of damaging your hair.
So, can you use leftover hair dye?
It depends. If you want to be safe, it’s best to throw it away and start fresh.
