- You should only mix a 30-volume developer with a hair dye if you want to lift more than three shades. Also, to lighten your very dark roots to even out the color of the lengths. The ratio will be 1 to 2.
- That is, you should mix two parts of the developer for every part of hair dye.
- You also have to consider the hair dye application and the exposure times. Everything will depend on what you want to achieve in your hair.

If I were you, instead of worrying about proportions and amounts, I’d see what I want for my hair. Coloring goes beyond the proportions of developer and hair dye.
Coloring, in short, is a chemical process. It causes permanent and irreversible changes to your hair. Once you apply a hair dye, nothing is ever the same. Even when you use a 20-volume developer.
Most permanent hair dyes are applied with a 20-volume developer. A 30-volume developer is used only in certain cases.
For example, it’s used with high lift hair dyes. They need more reaction to lighten the hair.
And all these chemicals generate some damage to the hair fiber. That damage translates into fragile, brittle, and dry hair.
So, I ask you:Do you want to lift your color more than 3 levels?
Then, you should use a 30-volume developer.
The next question is, do you know how to use it to avoid burning your hair?

How much 30-volume developer to mix with hair color. Exact proportions.
The exact ratio of developer to hair dye is 1 to 2.
For each measure of hair dye, you should add twice as much developer.
- If your hair dye is 60 cc, you should mix it with 120 cc of a 30-volume developer
- If your hair dye is 100 cc, you should mix it with 200 cc of a 30-volume developer
- If your hair dye is 125 cc, you should mix it with 250 cc of a 30-volume developer
Those are the right proportions for a high lift hair dye, or to lift the color by 3 levels. The 30-volume developer will open the hair fiber cuticles to deposit the new pigment, but it’ll also lighten the hair.
You can also use these proportions if you have very dark roots and want to match them to your lighter lengths.
How can you measure the right proportions?
- If you choose a high lift hair dye kit, the developer has the right size to mix with the hair color.
- If you buy the hair dye separately, look at the amount of the bottle and duplicate the amount for the 30-volume developer.
And always use the same container to measure both elements. It can be a pastry spoon, plastic measuring cups, or even a cap of liquid laundry soap.
How to apply the 30-volume hair dye and developer mixture correctly
Now you know the exact proportions. Still, the application depends on what you want to achieve on your hair. Let’s look at all the possibilities.
To lighten the roots with a 30-volume developer: start applying the hair dye on the growth.
If you dyed your hair blonde and your roots have grown out, you’ll need to use a 30-volume developer even if the kit includes a 20-volume developer. Otherwise, your roots will turn orange, and you’ll need to tone your hair.
- Comb your hair with a middle parting and hold each section with a hair clip.
- Prepare the coloring mixture in a plastic container by mixing the hair dye with the 30-volume developer.
- Apply the hair dye to one of the two sections you separated, only at the roots. Repeat the process on each section until the entire growth is covered. Comb the hair dye with a brush until the beginning of the lengths is covered. This will help you avoid tone differences.
- Leave it on for 40 minutes. Finally, rinse with plenty of lukewarm water.
Lift the hair color 3 levels: apply the hair dye from roots to ends.
Let’s play the matching game.
- Do you have very dark to dark hair (black 1, dark brown 3) and want to achieve medium tones?
- Does your hair have a medium tone (brown 4, light brown 5, dark blonde 6) and you want to achieve light tones?
- Do you already have a blonde base, blonde 7, light blonde 8, very light blonde 9, but want extra light shades?
Then, you’ll also have to mix a 30-volume developer with the hair dye.
What does this mean?
- If you apply an extra light blonde 10 hair dye on a blonde 7, you must use a 30-volume developer to even the color.
- If you apply a dark blonde hair dye 6 on a dark brown 3, you’ll need to use a 30-volume developer to remove the brown color from your pigmentation.
Let’s take a look at the step-by-step process:
- Comb your hair and separate it into 4 sections, from front to nape and from ear to ear, holding each section with a hair clip.
- Prepare the 30-volume developer and hair dye mixture. Remember the ratio is 1 to 2, and mix to a smooth consistency.
- Start applying the hair dye to one of the back sections, from root to tip, covering the entire surface. Repeat the procedure on all 4 sections.
- Once you finish, leave the hair dye on for 40 minutes.
- Finally, rinse with plenty of lukewarm water.
The 30-volume developer is used to dye hair only in very specific cases. Otherwise, a 20-volume developer is more than enough to generate the chemical reaction required by the hair dye.
