You probably know that some people simply pour bleach and/or bleach water down the drain. However, we would not recommend you do the same, and later on, you will know why! Instead, we suggest you check out the section below where you can find some methods that can help you with disposing of bleach.

Hazardous Waste

If you need to dispose of leftover hair bleach and you want to do it correctly without causing any damage to the environment, the very first thing you need to do is to check your local rules and regulations regarding this procedure.

They should have all the information on the proper disposal of bleaches and other similar chemicals.

Why should you go for hazardous waste disposal, you may wonder?

See, you should note that hair bleach is a hazardous chemical (even despite the fact that it is made for being applied to our hair)! But since it is considered hazardous, you should be ready that some waste facilities might not accept it.

However, if you spend some time and make proper research, you should be able to find some information on waste facilities that accept hazardous chemicals. At this point, please take into consideration that you can only opt for this kind of disposal method if you have hair bleach that is in an empty or used container!

Consider Diluting Leftover Hair Bleach

Diluting is another option possible. It can become handy for those who can’t find waste facilities that accept hazardous chemicals nearby. In this case, you can also dilute the bleach with water in order to pour it down the drain of your sink or bathroom.

Like this, you will reduce the level of danger that this product might have to the pipes.

The procedure of diluting your leftover hair bleach is very simple. Don’t worry, it doesn’t imply any measurements or precise dosage of water and bleach for mixing! Everything is much easier. All you have to do is to undergo several simple steps:

  • turn the faucet on first
  • then slowly pour the leftover bleach into the drain as the water runs
  • keep on pouring it until the container is empty
  • check that the container has no bleach in it
  • once all the bleach is down the drain, leave the water running for at least a minute
  • now you can turn the faucet off

As an alternative option, you can also choose to flush the bleach down the toilet.

However, this solution should only be done for small amounts of bleach! And if you decide to make use of this method, remember that you need to flush twice or thrice! Like this, you will make sure the bleach is completely diluted.

Like this, you are now aware of the most common and approved methods of leftover hair bleach disposal. Of course, this information will only be helpful for you if you dyed your hair at home since, in a salon, your colorist will dispose of the leftover product instead of you.

And even if you know the alternative methods of hair bleach disposal (like flushing it down the toilet), we would still ask you to try and find your local waste facilities that accept hazardous chemicals.

With their help, bleach will be surely disposed of according to all the rules and regulations, causing no harm to the nature and environment.

Why Proper Disposal Of Hair Bleach Is Important?

Since it is so important to dispose of leftover hair bleach correctly, many of you might be curious about why exactly this product is considered a hazardous chemical. To answer this question, you should learn more about what hair bleaches are made of.

Hair bleach is a chemical compound, which is obvious. And if you dye your hair often enough using it, you definitely know that hair bleach is used to lighten the color of hair. As for the components it consists of, hair bleach consists of the following components:

  1. hydrogen peroxide
  2. ammonia
  3. and water

This is why, when it is exposed to the air, it releases hydrogen peroxide and oxygen. However, this also makes it a dangerous compound to dispose of improperly! Why is that? Let’s take a closer look at the chemical ingredients of hair bleach to answer this question.

Let’s start with hydrogen peroxide. Hydrogen peroxide is a chemical compound that is made of hydrogen and oxygen. When it is exposed to the air, it releases hydrogen peroxide and oxygen.

Then we have ammonia, which is a colorless gas. Ammonia is used in a wide variety of chemical products, not only as a component of hair bleaches. You can also find it in fertilizers, explosives, dyes, etc.

However, ammonia can be poisonous if it is inhaled or ingested! When ammonia is exposed to the air, it releases nitrogen and water vapor.

The major chemicals in hair bleach that are considered toxic waste are hydrogen peroxide and ammonia, as you can understand now. If dumped in the trash can or poured down the drain or the toilet in their pure state, these compounds can cause serious harm to the environment and to the person who is disposing of them like this.

In addition, these compounds can also easily explode if they are not disposed of properly. Another harm they can cause is the contamination of the groundwater supply. It is therefore important to dispose of hair bleach in a safe and environmentally friendly way.

Now you can see that, while hair bleach is not technically toxic, it can still be classified as a product that contains hazardous chemicals. This is why it means that hair bleach needs to be disposed of in a specific way. Like this, one can make sure that it doesn’t harm other people or the environment.

How Long Is Hair Bleach Good For?

In order to dispose of your leftover hair bleach correctly, it is important to know not only how this should be done. In addition, you should be aware of the shelf life of this chemical product. Like this, you will know for sure when it can be considered the most harmful, as well as when it is still safe to use the leftover product should you have any after your previous dyeing session.

In general, hair bleaches last for nearly two years. However, it is still important to check the expiration date on the container of the box before you use it! Using expired hair bleach can be dangerous to your hair and overall health if you inhale its vapors.

Besides, if the product expires, it may not work properly (but this is minor damage in comparison to what can happen to your hair condition).

You should also keep in mind that hair bleaches degrade quickly when exposed to light.

In this case, the product begins to lose its effectiveness within approximately 20 minutes!

Also, if it contains bleach powder, developer, or other chemicals, the shelf life of the product may vary since it can be very difficult to give an accurate shelf life due to claims from different manufacturers on how long their product will last.

So always check your hair bleach before using it and, if you see that it is expired, better dispose of it according to the instruction we gave above than use it. It is easier to buy a new one than deal with damaged hair later, which will surely take more time and money!
