I dyed my hair and my roots are too light—how can I fix them?

Did you dye your hair, and your roots ended up being too light?


 The solution is simple—you just need to apply a dye that evens out the two tones you have in your hair. 

This is a really common problem when people dye their hair at home.

Do you know why your roots ended up lighter?


It has an easy explanation.

Many dyes, especially medium and light shades, use 30 volume developer.

The 30 volume developer lightens hair during the dying process.

In this way, while you apply the color, at the same time, you’re lightening your hair by two shades.


 When you rinse the dye mix, the long part of your hair will look like the tone you put in, but your roots will be lighter. 

This is because new hair growth lightens faster because it’s younger hair, as some professionals say.


So now you know, if you want your roots to look the same shade as the rest of your hair, you should use 20 volume developer.

Now that you know the reason, let’s explore the solution to this very common problem.

How do you even out roots that are lighter than the rest of the hair?

The first thing is not to give up hope, everything related to hair has a solution.

You should be sure about which tone you applied—this is the only way to fix the problem.

 If you don’t know which tone you applied to your hair with certainty, my recommendation is that you go to a beauty salon so that a stylist can help you. 

If you apply whichever tone of dye, you could have a real hair disaster on your hands. Don’t take unnecessary risks.


Once you’ve identified the tone you had put in, you can even out your roots with another tone that will blend the two colors in your hair.

For example:

  • If you put in a light brown 6, and your roots ended up lighter (light blonde 8), you can apply a medium blonde 7. In this way, your roots will darken by a shade, and the rest of your hair will lighten a shade.
  • If you applied a brown 4 and your roots ended up lighter (light brown 6), you can put in a chocolate 5.
  • If you dyed your hair a light blonde 8, and your roots ended up lighter (extra light blonde 9 or 10), you can put in a medium blonde 7.


As you’ll have noticed with the examples, the tones you can apply to fix your light roots are always an intermediate shade between your roots and the rest of your hair. 

In this way, you won’t lose the color range that you’re looking for, whether it’s blondes or browns, and you’ll be able to even out the difference in your hair tones.

But surely you’ll be asking: Why can’t I just apply the same tone again?


Of course, you can, but the difference between the roots and the rest of your hair will still be noticeable.

This is because the hair at your roots lightened with the first dying and the rest of your hair didn’t.

So, if you apply the same color again, even if it gets a little bit better, the difference will still be by one shade.

For this reason, the solution is always to find an intermediate shade that blends the two tones.


What volume developer should you use for the color mix?

As I mentioned at the beginning, your lighter roots are the result of the 30 volume developer.

Developer lightens hair.

It lightens your roots even more so, given that it’s young hair that has never been colored before.

To fix the difference between shades, I recommend that you use 20 volume developer.


 Your roots are already lighter, so the dye you’ve chosen will color your roots without a problem, and because it’s an intermediate tone, the rest of your hair doesn’t need more than 20 volume. 

Your hair will end up being an even, uniform tone.


If you were hoping to get an even lighter tone when you applied the dye, you still have time to achieve it.

Once you’ve evened out your color, you can start to apply even lighter shades.

But remember my advice, always with 20 volume developer.


For example:

  • If you evened out your hair with a medium blonde 7, when you’re changing the color, you should use a light blonde 8.
  • If you evened out your hair color with a light brown 6, when you’re changing the color, you should put in a medium blonde 7.

And in that way, whenever you’re changing your color, you’ll be lightening the tone gradually without running the risk that your roots end up lighter than the rest of your hair.
