How Much 20 Volume Developer to Mix With Hair Color? If you are using 20 volume developer, you will need to mix one part dye with two parts developer. This is the general rule but you might need to alter it according to the shade you want to obtain.

And when it comes to the 20 volume developer, mixing it in the correct amount is a top key to obtaining the results you want.

How Much Developer do you mix with Hair Color?

The secret of a perfect color lies in the mixture of developer and dye. As we mention this is usually one part dye to two parts developer. But you might need to mix more or less depending on the volume of your developer, the brand you use and the color you want to achieve.

If you don’t want a shade that is too light, you can mix one part developer with one part dye. This is great for people who don’t have gray hair so they have less to cover in the coloring process.

If you just started to see a few gray hairs, go for one part dye with 1.5 part developer. This will increase the coverage power of your mix and mask those gray hairs successfully.

However, if you have about 50% gray hair you should use the classic formula of one part dye with two parts developer. With this combination, you get complete coverage of your gray hair and shining, vibrant color.

Also, try to stick with the 20 volume developer for gray hair as it is not so damaging as the 30, 40 or even 50 volume developer.

Different developers come with strict instructions and even pictures to guide you. If you are not sure how to mix them with your hair dye, checking these instructions can help you a lot in the process.

But take into account that the texture of your hair, as well as the color, will influence this process. If you have thick hair with a dark color you might repeat the process in order to get to the shade that you want.

Extra tip: Never mix the developer and hair dye in a metallic bowl. Use a plastic bowl so your mixture will not be affected by the material. Also, make sure the bowl is big enough so you can mix the two ingredients properly. The result should be a homogeneous cream that you can apply on your hair.

What happens if you put too much developer in hair dye?

If you area beginner, you might take the risk of adding too much developer to your hair dye. Using more developer than you should is not a capital mistake but it will have certain effects on the final result.

More developers will lighten your hair more than you might have intended. However, if you do want a lighter color, using more developer is not the best option you have.

-You can use a 20 volume developer if you need to bleach your hair too. This developer will open the cuticles of your hair and allow the bleach to get inside of them in order to remove the hair color.

Using this type of developer when you bleach your hair is better than using a higher volume. It will not damage your hair as much while it will still give you the results you want.

How long should I leave 20 volume bleach on my hair?

Let’s start with an important point: bleaching your hair is never a healthy choice! However, if you still want to remove your hair color to free the path for a new one, you should make it as healthy as possible.

And the most important aspect is how long are you going to leave the developer and bleach mixture on your hair.

Each hair type and color reacts differently to the bleaching process. Some will lose color faster than others. This is why you should check the shade of your hair every two or three minutes after you apply the bleach and developer.

You will notice that the color of your hair gets lighter as time goes by. In most cases, it is just a matter of minutes to lose tones off your initial color.

The bottom line, you should never leave the bleach and developer mix on your hair for more than 30 minutes. You will notice the results anywhere between 15 minutes and 30 minutes and as soon as you are happy with your shade you should rinse your hair.

Leaving the bleach on your hair longer than you have to can damage it significantly. You can have burned hair or one that breaks easily.

Plus, your hair will lose its healthy shine and texture so even if you dye it in your favorite color, you will still not like the end result. Plus, too much bleaching time can dehydrate your hair a lot more than it can survive to. Dehydrated hair is dull, lacks softness and it becomes a lot more fragile.


Using a 20 volume developer can help you achieve the color you always wanted to have without a lot of hassle. You will be able to change your look in the comfort of your house as well. You don’t need a lot of experience either as long as you follow the instructions of your developer and the information in this guide.
