Why hair turns green after bleaching
As I told you at the beginning, the tone resulting from the bleaching of an ashy color is usually green. Now I want to go a little deeper into this subject, so that you can really understand how the bleaching mixture works on hair.
The main purpose of the bleaching mixture is to remove the pigments that are impregnated in the hair fiber.
Do you know what the underlying color is in the ashy tones?
- It’s the color blue.
- That means that any ashy tone will have blue pigments in its composition.
- When you apply the bleaching mixture, your hair will lighten to a yellow tone. The ashy tone, which has blue pigments, plus the color of your yellow hair, results in a green color.
- In other words, when you apply the bleach, the blue pigment wears away leaving green tones.
That’s why bleaching is a very complex chemical process, and it’s very important to consider the background of the hair. It´s not the same to bleach a previously colored hair as it is to bleach a natural hair.
Many women come to my salon with real rainbows in their hair, because they have no experience in this chemical process. They don’t know about exposure times or how to neutralize unwanted tones. They don’t even research whether their hair can be bleached or not.
But also, in some cases, they make an even more serious mistake. Can you imagine what that might be?
They bleach their hair twice! Yes, believe it or not.They bleach their hair again, thinking that the green will disappear. But, it doesn’t. Not only does the green tint not disappear, but also they damage their hair to the point of almost burning it.
So, if you can’t remove the green by performing a bleaching, what should you do?
You must neutralize the green tones.
How do you neutralize them? With the opposite color.
All tones have an opposite color that “cancels” them out.
- Green is neutralized by red
- Orange is neutralized by purple
- And yellow is neutralized by blue
In this case, to neutralize the green, you need a dye with red pigments.
Don’t panic! Your hair won’t turn red, but you must choose a dye that contains red tones. To identify them is very easy. Now you see, all dyes have a number that indicates the tone.
For example, 1.0 is black, 10.0 is platinum, and 5.0 is medium brown.
But you may have noticed that some dyes have a number followed by a dot. That number is the tone that has a numerical scale as well:
- Ash (blue)
- Iridescent / pearly (violet mulberry)
- Gold (yellow)
- Copper (orange)
- Mahogany (red)
For example, 4.3 is golden brown, 6.1 is light ash brown and 9.5 is very light mahogany blonde.
Now, if you bleached your hair and it resulted in having some green shades, you need a dye with mahogany tones, which are identified by number 5.
This way, the color’s highlights will neutralize your hair’s green tones.
How to choose the right hair color tone to neutralize unwanted greens
It’s time to choose the right tone of hair color to remove greenish tint from your hair.
The first thing to consider is the primary tone that your hair has reached with the bleaching. It can be:
- 7 dark blonde
- 8 blonde
- 9 light blonde
- 10 extra light blonde
Once you identify the tone, the rest is very simple.
If you can’t identify the tone easily, you can compare your hair with the photo in the coloring kit or ask the beauty shop for advice.
If you already know it, just look for a tone with red highlights (mahogany):
- 7.5 dark blonde mahogany
- 8.5 mahogany blonde
- 9.5 light blonde mahogany
- 10.5 extra light blond mahogany
Once you have the right color, you only have to proceed to the application:
- Comb your hair thoroughly.
- Prepare the revealing cream and dye mixture that comes in the kit.
- Apply the coloring mixture starting with the lengths and ends, and then continue with the roots and growth
- Respect the exposure time, approximately 40 minutes. Remember that each manufacturer has its own recommendations. So, read them carefully.
- Rinse your hair and …
The green will be gone!
If your hair turns green after bleaching, the bleach mixture most likely has not been able to remove the underlying tones in the hair cuticle.
Therefore, you should apply a color with mahogany highlights, always respecting your hair’s base tone. If your base tone is an 8, for example, you should apply an 8.5, mahogany blonde.
What you should never do is bleach your hair again, because that way you risk damaging it permanently.
