- If you purchased a permanent hair color kit, you won’t be able to make the hair dye darker before applying it to your hair.

- And if you have several dyes and want to know if you can use one of them to make the hair dye darker before applying it to your hair, I’ll tell you what to look out for.

Do you want to make the dye darker?
In this case, I can think of just one question: why do you want to complicate your life?
If you want a darker hair color, all you have to do is buy a darker hair color. I know, it seems like a no-brainer…
My answer would be the same if you asked me if you could lighten a dye before applying it: it’s not worth it.
So, I start by answering the obvious and then delve into the depths of the human mind. Our mind usually tries to go a little further and take advantage of resources.
That brings me to the next reason why you might want to make hair dye darker before applying it.
You probably notice it’s lighter than you imagined and don’t like that color in your hair.
In that case, don’t worry. After twenty minutes, the dye starts to develop or darken.
Alternatively, you might want to use some leftover hair dye. However, as it’s too light, you want to darken it. And we’ll go into this topic in more detail below.

How to darken permanent hair color before application
The first thing you should know is that you should always mix dyes that are similar.
If you have a permanent dye, you must darken it with a permanent dye. Alternatively, if it’s a semi-permanent dye, you must darken it with another semi-permanent dye.

So, if you have some leftover dye and you want to darken it, the formula is very simple:
- Hair dye number + hair dye number = total hair dye number = final number
Here are some examples:
- Light blonde 8 + brown 4 = 12 / 2 = dark blonde 6
- Very light blonde 9 + light brown 5 = 14 / 2 = blonde 7
- Blonde 7+ dark brown 3 = 10 / 2 = light brown 5
How to blend them?
You should always use one part dye to one part developer. This ratio should be used even if you mix dyes of different colors.
- Half a part of light blonde 8 + half a part of brown 4 = one part
- Half a part of blonde 7 + half a part of dark brown 3 = one part
Then, you have to mix that product with the developer.
You’ll need the same amount of a developer because the proportion is 1 to 1.
- If you have 60 ml of hair dye, you’ll need 60 ml of the developer.
- If you have 70 ml of hair dye, you’ll need 70 ml of the developer.
So, what should the quantities be?
- 30 ml of the first dye + 30 ml of the second dye + 60 ml of a developer
As you can see, mixing dye to darken a color is quite complex. You should be accurate with your proportions. So, if you want a darker color, it’s best to buy a new dye.
Now, if you want to darken the color of a semi-permanent dye, things are simpler.
How to darken a semi-permanent hair dye before application
Darkening a semi-permanent dye is easy because it isn’t applied with a developer. So, you don’t have to have exact proportions. You can mix dyes until you get the dark color you want.
If you want to darken pink, you can apply a little black or some blue until you find the color you want.
