Does hair dye expire?

Have you ever looked closely at a box of dye? it doesn’t come with an expiration date? This confuses a lot of customers.

A lot of you all must be curious to know that is the old dye safe to use. And I am also sure that the majority of you have used expired hair dye anytime in your life. 

The question which is often asked,

Does hair dye expires?

Yes, manufacturers say that hair dye does expire after 3years. However, they claim that an unopened box of dye never expires. 

No such incidence of danger caused by an old dye is ever reported, but the experts say that the chemicals in the old dye may cause some side effects. 

How can I know if the Dye has expired?

Manufacturers say that only an opened Dye has chances to expire, so the first thing to notice is whether the Dye is open or not.

An opened Dye increases the chances of dye being expired.

If the dye was opened and it has expired then it must be contaminated and smell bad. A dye once opened should be used completely as soon as possible.

Here are few ways you can test the Dye is expired or not:

1- Hair dye container was opened way before

Now that you know that hair dye can expire only after opening so, the dye that was opened long ago may have chances to expire.

The majority of hair Dyes come in two different containers which are mixed later on. If any one of the containers is left open without being used can ruin your hair dye.

The product in the container may oxidize after some time.

Oxidation is common in cosmetics and other products because the chemical inside them oxidizes when it comes in contact with sunlight, moisture, and air.

Even though, if your Dye does not contain any chemicals, it can lose its effect when kept open

2- Something might be wrong with the package

The age of the product can be easily indicated by its packaging. If your product is unopened and you still find it old with its packaging look for any of these traits and you must not use it.

  • Unusual color
  • Sour smell other than the smell of ammonia.
  • Damaged packaging
  • Cracked bottle
  • Leaking bottle

Why should you not use expired Dye?

An old or expired hair dye may not show adverse effects on your hair but may end up changing the color of your hair.

There is no evidence of any kind of damage caused to the scalp or hair with the use of an old die.

However, some cases have been reported where the hair color changes into some unwanted hair color. This was because of the oxidation of the metal inside the hair dye.

In the case of permanent hair dye, you may face allergies and reactions due to harsh chemicals infused in them.

Any irritation, redness, soreness, itching is a sign of an allergy. Consult professionals, anytime you face these.
