Hair bleach is a common household chemical used to lighten hair color. It can be dangerous if not disposed of properly, so it’s essential to know how to get rid of it safely. This blog post will discuss how to dispose of hair bleach and keep your home and environment safe!

What is hair bleach made of?

Hair bleach is a chemical solution that lightens the color of hair. It’s composed of hydrogen peroxide, ammonia, and water. When it is exposed to air, it emits hydrogen peroxide and oxygen. This makes it an unsafe chemical to dispose of carelessly.

Hydrogen peroxide is a chemical composed of hydrogen and oxygen. It yields hydrogen peroxide and oxygen when exposed to air. Ammonia is a colorless gas that is utilized in a variety of applications, as well as hair bleaches. It’s also used to make fertilizers, explosives, and dyes and can be toxic if breathed or ingested. When ammonia is exposed to the air, it releases nitrogen and water vapor.

How long is hair bleach good for?

Hair bleach has an average shelf life of two years. However, before using it, be sure to verify the expiration date. Using expired hair bleach can be dangerous. It may not work as intended and result in your hair being damaged.

How to Dispose of Hair Bleach

Hair bleach deteriorates rapidly in the light. Its effectiveness fades within 20 minutes. If there is any bleach powder, developer, or other chemicals in the product, its life span may differ significantly.

Hair bleach is available in various formulations, including bleach powder and developer. Due to varying claims by manufacturers on how long their product will last, it may be hard to provide an accurate shelf life. Some makers suggest that their hair bleach powder will keep for a year after being combined. Unfortunately, this isn’t usually the case for most producers.

How to dispose of hair bleach properly?

While the process of hair bleaching isn’t complicated, how you dispose of hair bleach is very important. Improper disposal of hair bleach can lead to environmental contamination and harm your health.

The first step in disposing of hair bleach is to read the label. Many products will have specific instructions on how to dispose of them safely. If there are no instructions on the label, follow these general guidelines:

1. Take it to the local hazardous waste disposal center

Taking it to your local hazardous waste collection site is the best approach to get rid of it. These facilities are generally located near most major cities and are designed to handle dangerous chemicals. They should be able to dispose of your extra bleach for you properly.

2. Donating or sharing excess hair dye

If you can’t get rid of the excess hair dye on your own, consider giving it to a friend, neighbor, or family member. Perhaps you know someone who would also want to color their hair in the same hue as yours! You may ensure that any leftover pigment is used up and doesn’t pollute the environment.

You may also dye each other’s hair to ensure you don’t miss any spots! However, please be advised that the new, mixed dye (dye combined with the developer) should be used immediately after one hour. Opened hair dye degrades rapidly and is no longer effective after an hour; additionally, it’s unsafe to store. After you’ve used up the hair color, rinse the container and recycle it.

3. Call the local recycling center

If there is no hazardous waste disposal center in your area, you can ask your local recycling facility if they will take hair bleach. If you can’t find a safe way to eliminate hazardous waste in your region, call your local trash collection firm. Waste facility employees will almost always be able to tell you how to handle hazardous materials properly.

You may also recycle your empty hair bleach bottles if they are empty. Most recycling centers take plastic bottles, but it’s good to double-check whether they’ll take them if they’ve been used to hold hazardous chemicals like bleach.

Can hair bleach go down the drain?

Hair bleach is perfectly safe to put down the drain as long as it is diluted with a lot of water and not combined with other chemicals. It’s not good to throw hair bleach down the toilet since it can harm septic systems. It might also eliminate helpful bacteria that help break down waste and destroy aquatic life.

However, if you are concerned about the environment, it is preferable to contact your local hazardous waste management firm to learn how to dispose of your unused bleach properly.

Try a natural, harmless alternative

Consider using a natural hair dye if you don’t want to deal with hazardous traces of previous hair color. There are several plant-based hair dyes on the market. These dyes are less harmful to the environment and one’s health than traditional chemical ones.

Henna is a fantastic natural dye alternative that you can certainly try if you want to color your hair. It’s a safe and environmentally friendly option you may consider when dying your hair. You may conveniently compost the leftover henna rather than throw it in the garbage. Reach out to your hairdresser or colorist to learn about these incredible natural or less damaging alternatives.

How to use hair dyes safely

Now that you know how to dispose of hair bleach, it’s essential to learn how to use it safely. Hair dying is a highly creative, gratifying, and enjoyable process. You should, however, use them with caution since they’re manufactured with artificial chemicals.

How to use hair dyes safely

You must follow the instructions on the product box to safely handle the color. An allergic response can be caused by mishandling the color. When it comes to hair dyes, here are a few safety precautions you should keep in mind:

  • Make sure to do a test patch to see whether or not the dye causes an allergic response. Apply a dab of the color behind your ear and leave it there for the recommended time to check for product efficacy. Don’t use it if you experience any allergy symptoms, such as redness, itching, or burning when applying the dye to your scalp or hair.
  • When working with hair dyes and bleaches, wearing latex, rubber, or nitrile gloves is a must. The gloves will keep your hands safe from direct contact with the substance. If you get dye stains on your hands or fingernails, remove them as soon as possible using a high-quality hand cleanser.
  • All hair dyes and other hair products should be out of reach for your kids and pets. Accidental ingestion can have severe consequences. Always work in a well-ventilated area when using hair dyes. This is because the smell of synthetic dyes can be pretty solid and disgusting, so working in a ventilated room is not necessary.
  • Wear a face mask if you can’t tolerate the pungent odor of hair dyes. Never leave the hair dye on your hair for longer than the recommended time on the box. Hair bleach is equally harmful to your locks and scalp, so don’t apply it unless directed by a professional.
  • Do not mix different hair dye types. Rinse your scalp with water as soon as possible after applying the hair color. Never use hair color on your brows. The dye can cause eye swelling and vision problems if you are allergic to it. It can also induce eye infections and eventual blindness.


Now that you know how to dispose of hair bleach, you can use it without worrying about the consequences. Just follow the safety precautions and instructions on the product box to avoid accidents. Consider using henna if you’re looking for a natural and harmless alternative to hair dyes. It’s a great way to color your hair without damaging it. Thanks for reading!
