Does Garnier hair dye expire? (When is the expiration date)

The shelf life of Garnier hair dye expire after 3 years from the date of manufacture. The shelf life of a product is how long it can be stored until its quality deteriorates to unacceptable levels.

Going to a hairdresser and getting your hair dyed can be expensive, especially if you are like most people who always have a plan to dye their hair soon.

Sometimes, you forget about the Garnier hair dye you have laying around in the cupboard and find out you’ve been wanting to change your hair color from time to time.

When you check the box for an expiration date, you can’t seem to find one. So can you still use it? Will it still work? And will it color your hair?

Hair dyes are not provided with “expiration dates” today because they should be good for a lifetime if properly stored.

But they do go bad and can have some unintended side effects. If you are still using them, you might find your hair or skin feels bad or starts to break.

Recently, people have started to question whether it is safe for them to use their Garnier hair dye that has been laying around in the bathroom. This blog post will answer any questions you might have about this topic.

Why Does Hair Dye Expire or Go Bad?

Hair dye expires for two main reasons: the ingredients in the dye start to break down, or the container is compromised and lets air in.

The most common reason for expiration is that the ingredients in hair dye can break down over time. The chemicals that make up hair dye are very sensitive to light, heat and humidity. This means they can break down faster when exposed to these elements.

The other reason is that the container may not be sealed properly and let air into it. This can cause bacteria or mold to grow inside of it, which will shorten its shelf life even more.

Hair dye is a chemical that can expire or go bad. The expiration date is usually on the bottle and it varies depending on the type of hair dye you have.

Some other reasons why hair dye might expire or go bad:

  • The color might turn a different shade than what was expected
  • The color might not last as long as expected
  • The color could get duller over time

How Long Does Garnier Hair Dye Last Unopened?

There are a few ways to determine if your hair dye has expired. The first way is to check the expiration date on the packaging.

If you can’t find the date, you can do a quick test by adding water to the dye and then checking it in 20 minutes. If it changes color, then it’s time to throw away your dye.

If your hair dye has been sitting around for a while, you may notice that it doesn’t work as well as before or that it leaves an odd smell after application. This is because hair dyes expire over time and need to be replaced every 12 months or so.

Why are There No Expiration Dates on Hair Dye Boxes?

The answer to this question is not a simple one. There are many reasons why manufacturers do not put expiration dates on hair dye boxes.

The second reason is that it might create an unnecessary panic among consumers who might rush to buy something before it becomes useless.

Dyeing Hair At Home Vs At The Salon?

When it comes to hair color, there are two options – dyeing hair at home or going to a salon. Dyeing your hair at home is cheaper than going to a salon and you can do it in the comfort of your own home. However, there are some things that you need to keep in mind when doing it yourself.

Some of the most common mistakes people make when dyeing their hair at home are:

  • Not using enough dye (which can result in uneven color)
  • Not following proper instructions from the manufacturer (which can result in damage)
  • Not using gloves (which can lead to allergic reactions)
  • Using too much heat which can also damage your hair


People dye their hair using hair dye that should last three years in storage. Most manufacturers give this amount of time as the shelf life of the bottle or tube.

Old dye can lead to bad results. A lot of color won’t change and you may end up with odd coloring or a green tinge.

Many hair dyes that are outdated could actually cause some negative effects, like triggering allergies or other health risks.

Most of them are actually over a 3 years old and may contain harmful chemicals that can also be exacerbated by their age.
