How to prepare the hair dye mixture? How much developer should you use?


peroxide choice

Are you planning to dye your hair from the comfort of your own home?



Let me tell you that to get good results, you need to mix the ingredients correctly.

It’s like following your grandmother’s recipe for your favorite cake to the “t.”


 I started dyeing my hair in my home a long time ago, for the simple reason that I was tired of spending money at the salon.  

It can be beautiful sitting in a chair while they massage your scalp. You drink a coffee while they do the color, but when it comes time to pay, you go from a queen to a beggar.


So, I decided to stop feeling like a queen for a day in the salon and dye my hair by myself.

But I still remember the first time I did it. Even though now I laugh about it, in that moment, I cried.

The color ended up a disaster!



In some pieces it looked good, but it in others, it was as if I had wiped on the bleach.

What the hell had happened?


 After hours of looking at YouTube videos and reading hundreds and hundreds of blogs, I came to the conclusion that I had made mistake in the proportions. 

Yes, just as you read it.


Coloring is nothing more and nothing less than a mathematical equations where you should respect the proportions of the developing mixture and the color.


For each hair dye, it is always necessary to buy the appropriate developer, also called peroxide and color.


The hair color and developer are mixed in a certain proportion to form a dye mixture that is later applied to the hair.

The proportion of the mixture is usually 1 to 1, 1 to 1.5, or 1 to 2. For example, if you want to get a stronger lighting effect.


If you don’t want your attempt to dye your hair at home to turn into a disaster, like what happened to me the first time, stay with me.


Because I will tell you:

  • How developer acts in the color mixture
  • What volume of developer you should choose to get the color effect that you want
  • What volume peroxide is best to use according to your hair type
  • Advice for before you start the coloring process



What is developer and what is it used for in a color mixture for your hair

mixing ratio of dye

Peroxide or developer is a totally essential element in the hair coloring process.


It is in charge of opening the hair cuticle so that the pigments can go in and produce a color change.


 Without peroxide, you will never achieve and significant changes in your hair color. 

Because it activates the color, as well as helps give you uniform coverage of the color.

It also works to eliminate the natural pigment of the hair, like in cases of bleaching the hair.


Up until here, everything is very beautiful, and seems like the developer is your new best friend.


But, if you want to obtain the best results, it is important to use the correct concentration of the developer.

This choice also will depend on the color that you want to get, the level of lightening, and the type of hair.


What volume developer should you choose to make the color mixture

 Choosing the correct developer is crucial to obtain the color that you want.

The strength/concentration of the developer is expressed in percentages (%) or unites of volume (Vol.)


The higher the number, the stronger the developer, and therefore, the lighter the color of your hair will end up.

But, don’t worry. It seems complicated, but it isn’t.


At least, it won’t be for you, because below, I’m going to give you a complete guide so that you can choose the volume of developer without being afraid of choosing the wrong one.


1) Choosing the developer for the type of dye

Semi-permanent dyes


Semi-permanent dyes are combined with weaker developers, meaning, 10 or 20 volumes. Some of these types of dyes don’t even need peroxide because they use natural pigments.

But of course, they last less time in your hair.


Permanent colors

These colors are used with moderate developers, meaning, 20- to 30-volume peroxide.




If you need to bleach your hair, you will need a stronger developer to mix with the bleaching powder or cream, generally 40-volumes.

But, careful, if you use 40-volume developer, you should take extreme care of your hair, because you can do irreversible damage.


2) Choosing a developer by level of lightening or darkening

Lightening your hair and darkening your hair are not the same thing.

Even though you should always keep in mind that a hair dye will only lighten your hair two tones from your natural hair.



  • If you use 10-volume developer, you will darken your hair one tone, and that will only happen if you go from a lighter tone to a darker one, never the other way around.

It will also work to get a tone with the same level of luminosity.


  • If you use a 20-volume developer, you can lighten your hair up to two tones.

It is also what you use to dye your gray hair.


  • 30-volume developer is mixed with the dye to lighten hair up to three tones, and color very resistant gray hairs.



It isn’t mixed with the dye, but with bleaching powder.

But like I said before, you run the risk of burning your scalp and hair.


3) Choosing the developer according to hair type

Your hair type can also influence the result of your hair.

For example, fine hair is easy to lighten, because the color penetrates quicker into the hair fiber. While thicker hair can be more resistant during the coloring process.



Fine hair

If you have fine hair, the coloring will be faster, whether you want to lighten it or darken it.

You can use 10-volume developer.


Normal hair

For this type of hair, I recommend that you use 20-volume developer.



Thick hair

This hair is more difficult to lighten or darken, so I recommend that you use 30-volume developer.

In hair with lots of gray hairs, it is also appropriate to use 30-volume developer.


4 pieces of advice for before you dye your hair

  • We women always perceive hair color darker than what it really is. If you are stuck between two tones, choose the lighter one.
  • The coloring mixture shouldn’t be prepared until you are ready to apply it. You should apply the color mixture immediately to assure the best penetration of the color. Remember that this mixture is only active for 60 minutes.
  • If you have more than 60% white hair, choose a tone darker than the color that you want.
  • Don’t forget frequent coloring causes significant damages to the stalk of the hair. If you can, use products like Olaplex, before and after the dye to prevent damages produced by the chemicals present in the dye.



Now you know what volume developer you should use the next time you want to dye your hair.

What volume peroxide do you use when you change the color of your hair?
