Are you looking to make a 25-volume developer for your hair coloring needs? Look no further, as we have outlined a simple and easy process for creating your own 25-volume developer at home.

How to Make 25 Volume Developer

How to make 25 volume developer is an essential skill for anyone involved in hair coloring and bleaching. Volume developers are critical in activating hair dye and lightening agents, allowing for effective and precise color changes.

A 25 volume developer, which contains 7.5% hydrogen peroxide, sits between the standard 20 and 30 volume developers, offering a balanced option that provides significant lightening without excessive damage.

In this guide, we will walk you through the process of accurately diluting a higher strength developer to achieve a 25 volume developer, ensuring consistent and professional results.

What Will You Need?

Before we begin, make sure you have the following items ready to create your own 25 volume developer:

  • A bottle of 30 volume developer
  • Distilled water
  • Measuring cup or scale
  • Empty mixing bowl or bottle

It is essential to use a measuring device and distilled water for accurate and safe dilution. Avoid using tap water as it may contain impurities that can affect the effectiveness of your developer.

10 Easy Steps on How to Make 25 Volume Developer

Step 1: Calculate the Required Amount

To create a 25 volume developer from a 30 volume developer, you must dilute it with distilled water. This can be achieved by calculating the appropriate ratio.

A 30 volume developer contains 9% hydrogen peroxide, while a 25 volume developer contains 7.5%. Hence, the ratio of 30-volume developer to distilled water needs to be adjusted accordingly.

Step 2: Measure the 30 Volume Developer

Using your measuring cup or scale, measure the amount of 30 volume developer you’ll need. You will use 5 parts of the 30 volume developer for this process.

Using your measuring cup or scale

If you want to prepare a specific volume of 25 volume developers, calculate the total volume and then divide by 6 to get the amount of 30 volume developers required. For example, if you want to prepare 60ml of 25 volume developer, you would need 50ml of 30 volume developer.

Step 3: Measure the Distilled Water

Once you have measured the required amount of 30 volume developer, you will need to calculate the correct amount of distilled water. For every 5 parts of 30 volume developer, you will add 1 part of distilled water.

Continuing with our example of preparing 60ml of 25 volume developer, since we used 50ml of 30 volume developer, you will need 10ml of distilled water. Accurate measurements are crucial to ensure the correct dilution and performance of your 25 volume developer.

Step 4: Mix the Ingredients Together

Pour the measured 30 volume developer into your empty mixing bowl or bottle. Next, add the distilled water to the bowl or bottle. It is essential to combine the ingredients thoroughly to ensure an even distribution of hydrogen peroxide throughout the mixture.

Step 5: Stir or Shake Well

Using a clean mixing tool or by securely sealing and shaking the bottle, mix the 30 volume developer and distilled water together. Ensure that the mixture is homogenous and that there are no visible streaks or separations. A well-mixed developer is crucial for consistent and predictable results during hair coloring or bleaching.

Step 6: Check the Consistency

After mixing, check your developer’s consistency. It should be smooth and free of any lumps or particles. An even consistency will help with the application process, ensuring that the developer spreads uniformly on the hair for a consistent lift.

Step 7: Label Your Developer

Once you have ensured that your 25 volume developer is well-mixed and consistent, it is important to label the container. Use a waterproof marker to write “25 Volume Developer” on the bottle along with the date of preparation.

This step is crucial to avoid any confusion in the future, especially if you regularly mix different volume developers. Accurate labeling helps maintain organization and ensures that you always use the correct product for your hair coloring needs.

Step 8: Conduct a Patch Test

Before using your newly created 25 volume developer on your hair, you should conduct a patch test. Apply a small amount of the developer to a discreet area of your skin, such as behind your ear or on your inner elbow.

Leave it on for 24 hours and check for any signs of irritation, redness, or itching. Performing a patch test helps you ensure that you do not have an allergic reaction to the developer.

Step 9: Store the Developer Properly

Proper storage of your 25 volume developer is essential to maintain its effectiveness over time. Store the bottle in a cool, dark place away from direct sunlight and excessive heat.

Exposure to light and heat can degrade the hydrogen peroxide, reducing the developer’s potency. Always ensure the cap is tightly sealed to prevent any leakage or contamination.

Step 10: Use as Intended

Your 25 volume developer is now ready for use. Follow your usual hair coloring or bleaching routine, applying the developer as directed by your product’s instructions. Remember that a 25 volume developer offers a balanced option, providing noticeable lift and lightening while minimizing the risk of excessive damage.

It’s ideal for those looking for a middle ground between the mild effect of a 20 volume developer and the stronger lift of a 30 volume developer.

By following these steps, you can confidently create your own 25 volume developer at home, ensuring professional and consistent results with every hair coloring session.

5 Additional Tips and Tricks

  1. Measure Accurate Ratios: Measure the hydrogen peroxide and purified water precisely to ensure the correct concentration of the developer. Using a digital scale or precise measuring cups can help achieve the desired 25-volume developer.
  2. Mix Gradually: When combining hydrogen peroxide and water, add the water slowly while stirring continuously. This helps to achieve a consistent mixture and avoid any clumping or uneven distribution of the active ingredient.
  3. Avoid Contact with Skin: Hydrogen peroxide can irritate the skin, so be sure to wear gloves while handling it and avoid getting it on your skin. If contact does occur, rinse off immediately with water.
  4. Keep a Record: It’s always a good idea to keep track of your developer mixtures and record the ratios used. This can help you replicate successful results in the future and troubleshoot any issues that may arise.
  5. Dispose of it Properly: According to local regulations, hydrogen peroxide should be disposed of properly. Do not pour it down drains or into bodies of water as it can harm the environment. Instead, consult with your local waste management agency for proper disposal methods.

5 Things You Should Avoid

  1. Using the Wrong Concentration of Hydrogen Peroxide: Starting with 12% hydrogen peroxide (40 volume) as the base is essential. Using a different concentration can lead to an incorrect final volume, affecting the developer’s effectiveness and safety.
  2. Ignoring Protective Gear: Always wear gloves and safety goggles while handling hydrogen peroxide. Even small splashes can cause irritation or damage to the skin and eyes, so protection is crucial.
  3. Mixing in Unclean Containers: Ensure that the container used for mixing is clean and free from any residues. Contaminants can react with hydrogen peroxide, altering the developer’s concentration and efficacy.
  4. Neglecting Proper Storage: Store hydrogen peroxide and the mixed developer in a cool, dark place. Exposure to light and heat can degrade the solution, rendering it less effective and potentially unsafe.
  5. Rushing the Mixing Process: Take your time when mixing hydrogen peroxide with purified water. Rushing the process can result in an uneven concentration, leading to inconsistent hair coloring results.

By avoiding these common mistakes, you can ensure that your 25 volume developer produces the desired results without any negative side effects.

What Type of Hair is Best Suited for 25 Volume Developer?

The 25-volume developer is best suited for hair that is in good condition and has not been previously bleached or damaged. It is also suitable for natural hair colors in the range of medium brown to dark blonde. Using a 25-volume developer on already lightened or damaged hair can lead to excessive damage and breakage.

Additionally, it may not be suitable for those with sensitive scalps or allergies to hydrogen peroxide. If you have any concerns about using a 25 volume developer on your hair, consult a professional colorist before proceeding with the application.

They can assess your hair’s condition and advise on the best course of action for your specific hair type.
