How Does 40 Volume Developer Work?

The 40 volume developer is super strong for bleaching hair. It has a lot more of the chemical hydrogen peroxide in it compared to other developers. Having so much hydrogen peroxide makes the 40 volume developer really good at removing color from hair fast. It can make hair a whole lot lighter in just a little bit of time.

When mixed with bleach, the 40 volume developer activates and speeds up the bleaching process. It breaks down the natural pigments in the hair shaft called melanin. The hydrogen peroxide in the developer acts as an oxidizing agent to penetrate the hair and dissolve the color pigments, resulting in hair lightening.

The strength of the 40 volume developer provides more lifting power and is often used for significant color transformations, especially for dark hair. However, it is important to be cautious because the strong developer can also increase the risk of hair damage.

How Do Bleach and Developer Interact with Each Other?

The main purpose of hair bleach is to strip the color from your hair. It does this by entering the hair shaft and breaking down the pigment molecules known as melanin because these molecules are responsible for giving your hair its natural color. By that way, the hair color is removed.

However, bleach cannot accomplish this task on its own, but it requires the assistance of a developer. The developer is really important for making the bleach work. It has hydrogen peroxide in it that helps open up the outer layer of the hair strand. When this outer layer is open, the bleach can get inside the hair easily. This allows the bleach to do its job of taking the color out of the hair.

Factors To Consider When Using 40 Volume Developer With Bleach

  • Hair condition

Before mixing the strong 40 volume developer with bleach, you need to think about the current state of your hair. Look at things like any treatments you’ve done before, if your hair is damaged, and how healthy your hair is overall. If your hair is already dry or damaged, using the really strong bleach mixture can cause even more damage. 

Also, you should take into account if there are any scalp sensitivity or hair breakage issues. Evaluating your hair’s elasticity by gently stretching a strand can indicate its health. Healthy hair should have some flexibility without breaking easily.

  • Desired level of lift

The first thing you need to figure out is exactly how light you want to go with your hair color. Think about your natural hair color and any color treatments you’ve had done in the past. That will help you decide if you want to just go a few shades lighter or make a really dramatic change to a much lighter blonde shade. 

Significant lightening requires multiple bleaching sessions or professional assistance, particularly for individuals with darker hair. Therefore, it is crucial to have realistic expectations about how long the process takes to achieve the desired outcome.

  • Developer-to-bleach ratio

Getting the right mix of developer and bleach is super important if you want good results. Developers come in different strengths – some are more potent than others for lifting color. You’ll want to pick a developer strength based on how much lighter you want to go and also how healthy your hair is right now. Using too strong of a developer can really damage your hair.

The key is finding that sweet spot where the developer and bleach work well together without frying your hair. It is recommended to do a little strand test first. That way you can see how much lift you get and if there’s any potential damage. Then you can tweak the developer-to-bleach ratio if needed before doing your whole head of hair.

How Much 40 Volume Developer To Mix With Bleach?

When mixing the really strong 40 volume developer with the bleach powder, you need to use the right amounts. The best mix is one scoop of bleach powder with two scoops of the 40 volume developer.

Doing it this 1 to 2 ratio helps get your hair light, but not so strong that it damages your hair too much. Too much developer can really hurt your hair. But the one scoop bleach to two scoops strong developer is a good balance to lift the color without too much damage.

Remember, how much 40 volume developer to mix with bleach may vary based on your specific needs. If you have very dark or resistant hair, you will need slightly more developer. If your hair is already damaged or sensitive, you should use a bit less developer to minimize harm.

Before applying the mixture to your entire hair, do a strand test by applying a small amount of the mixture to a section of hair to see how it lightens and check for any negative reactions or damage. This effort will help you determine the right ratio for your hair.

Finally, always follow the instructions provided with your bleach and developer products, as they have specific guidelines for mixing ratios.

If you are unsure about the ratio or have complex color goals, it is best to consult a professional hair colorist who can give you personalized advice and ensure the best results while keeping your hair healthy.

How to Mix Developer and Bleach

Let’s move on to the process of mixing and determining the right amount of liquid or cream developer to combine with bleach. The ratio between bleach powder and developer is crucial for successful hair lightening.

As mentioned earlier, the ideal bleach-to-developer ratio is 1:2. This balanced ratio will yield a smooth and creamy mixture that can be easily applied to the hair. Here’s a simplified guide for you:

  • Mix 50 grams of bleach powder with 100 grams of developer.
  • Mix 100 grams of bleach powder with 200 grams of developer.

The same formula applies if you prefer measuring in ounces instead of grams.

If you have a larger container, you can use measuring spoons or a kitchen scale to measure the appropriate amounts of powder and developer. Just remember the recommended ratio to mix one part bleach powder with two parts developer.

Additionally, if you want to use the bleach for painting techniques like balayage or if you only want to lighten a specific section of your hair, you can make the mixture thicker. In such cases, a 1:1 ratio between bleach powder and developer is recommended.

Tips and Best Practices

Gradual approach

If you aim for a significant color transformation, it is generally advisable to take a gradual approach rather than urging to achieve drastic changes in a single session. This approach helps minimize damage and allows you to assess how your hair reacts to the bleaching process. What you should do is to plan multiple sessions spaced apart to gradually lighten your hair to the desired shade.

Professional advice

Again, if you are uncertain about the bleaching process or if your hair has specific needs, it is highly recommended to consult a professional hair colorist. They have the expertise to assess your hair’s condition, recommend suitable products and techniques, and guide you through the process safely. Professional advice can help you achieve the best outcomes while minimizing the risk of damage.

Aftercare

Proper aftercare is crucial to maintain the health and integrity of your hair after bleaching.

  • Moisturize: Bleaching can strip the hair of its natural oils, which can lead to dryness and brittleness. Use moisturizing hair products, such as deep conditioning treatments or leave-in conditioners, to replenish moisture and restore vitality.
  • Protect from Heat: It is best to minimize the use of heat styling tools, such as straighteners or curling irons, as they can further damage bleached hair. If heat styling is necessary, apply a heat protectant spray to minimize heat damage.
  • Limit Washing: Avoid excessive washing, as frequent shampooing can strip away natural oils and cause further dryness. In addition, you should opt for gentle and sulfate-free shampoos designed for color-treated hair, and consider washing your hair less frequently to retain moisture.
  • Trim Regularly: Regular trims to remove any split ends or damaged hair can promote healthier growth and maintain the overall appearance of your hair.

FAQs

What happens if you use excessive bleaching powder?

When you use more bleaching powder than the recommended bleach-to-developer ratio, the mixture becomes too thick. This thick consistency makes it difficult to spread evenly and causes poor adherence to the hair strands. As a result, you may end up with uneven or patchy bleaching.

What if you add too much developer to the bleach?

Adding too much developer to your bleach mixture makes it too runny. The runny consistency can lead to dripping and spreading on your face and arms. Apart from creating a messy situation, excessive developer can also cause skin irritation.

Do you need to adjust the ratio based on the volume of developer?

No, the volume of the developer you use has no impact on the ratio between bleach and developer. Regardless of the developer volume (such as 10 volume, 20 volume, etc.), you should still maintain the 1:2 bleach-to-developer ratio.

How much 40 volume developer to mix with color?

When mixing 40 volume developer with color, the general recommendation is to use equal parts of developer and color. For example, if you have 1 ounce of color, you should mix it with 1 ounce of 40 volume developer. Mixing equal amounts of hair color and developer will be sufficient to change your hair color by one or two shades.
