- To perfectly cover your blonde hair with a black dye, the first thing you have to do is use a color filler.
- The color filler is simply a dye that you will apply without peroxide as if it were a moisturizing mask. You should choose an intermediate color, like chestnut brown or chocolate. This way, later, the black pigments of the final dye will be deposited more easily.
- After using the color filler, you will immediately have to apply the black dye.

Surely, you have heard the phrase: “black covers everything”.
It is partially true. If you paint a yellow wall with black paint, you will be able to cover the yellow perfectly.
But, in matters of hair, things are not so simple.
Sometimes, instead of black, your blonde hair can turn out with an indescribable color.
That’s what happened to Juana, one of my clients.
For years, Juana has had very light blonde hair. A blonde that we achieved after several bleaching procedures.
Don’t ask me why one day she woke up thinking she liked the Morticia look of the Addams Family better.
So, she thought, “I will dye my blonde hair black and I will get it.”.

But, she didn’t take into account the history of her hair. She didn’t take into account that her hair had been bleached. So, when she rinsed off the dye and her hair dried, all she had from Morticia was only black humor.
Her hair was an awful black faded half greenish color. What had happened?
Very simple.
Bleaching takes all the color out of the hair. When she applied the black dye, her hair didn’t have enough base pigments for the black to settle. Then, it turned green.[/your_highlight]That’s why, to avoid the risk of your blonde hair turning green when you dye it black, you should use a color filler.

How to dye your blonde hair black without turning it green
When the hair fiber does not contain pigments, as in the case of bleached blonde hair, any dye you apply will not be able to settle and will look faded or green.
If you want to color your blonde hair black, you must add a pigment base to the hair fiber so that the new color will settle.
That is achieved with the color filler.
Don’t panic!
I have two pieces of good news for you:
- applying a filler color is very simple
- and it does not damage the hair
It is simple because it is applied just like a dye.
And it doesn’t damage the hair because the dye is applied without mixing it with peroxide.
Why is it applied without peroxide?
Because, this way, the hair will absorb the pigment like a moisturizing mask or conditioner. The color filler doesn’t break the hair cuticles. It just naturally deposits the pigments and the hair absorbs them.
There are three fundamental things you need to know.
- When you make the transition from blonde to black hair, to avoid green color, you must have two dyes at hand: one of an intermediate color and the other of black color.
Why do you have to have both dyes at hand? Because you will apply the black dye directly on the color filler, without rinsing. That is, you cannot do the color filler and apply the black dye the next day.
You should definitely do everything on the same day!
- To make the color filler you must use a permanent dye.
Because semi-permanent dyes fade with washing.
- You must choose the correct intermediate color to make the color filler so that black is fixed in the hair fiber and the greenish reflections do not appear.
For this, you can divide the level of the blonde color by two. For example:
- If your hair is extra light blonde 10, you should apply a 5
- If your hair is very light blonde 9, you should apply a 4 or 5
- If your hair is light blonde 8, you should apply a 4
- If your hair is blonde 7, you should apply a 4 or 3
Once you have your intermediate dye (the one you will use as a color filler) and the black dyeing kit, you can begin the transition from blonde to black.
Applying color filler to go from blonde to black
I recommend that you make the transition from blonde to black hair, during a day that you are not in a hurry. A day that you can dedicate yourself entirely to your hair.
This way, you can avoid mistakes and green hair appearing as a result of poorly applied coloring or rushing.

- Leave it in for 30 minutes.
- Do not rinse.
Stage 2: application of the black dye
- In a plastic container, mix the black dye and the developer.

- Leave it in for 30 to 40 minutes.
- Afterward, rinse your hair with plenty of warm water until it runs clean.
