How To Fix Green Hair From Ash Dye - Blonde Help

Washing off bleach or toner to discover that your hair has developed a green tint is terrifying. Thankfully there are many ways you can fix green hair at home using dye, toners, shampoos, or even more bleach. Here is your complete guide to how to fix green hair with cosmetics you can easily buy online.

Why Does My Hair Have a Green Tint?

The first question you may ask yourself is why hair turns green, particularly if it has never happened to you before. There are several reasons why hair turns green, but it all has to do with a lack of balance in hair pigments. Usually, the red in the hair cancels blue and yellow pigments from ashy toners, oxidized mineral buildup, or even a dark dye applied on hair that is too light.

What Causes The Green Hair Problem? Why Did My Hair Turn Green?

There are several reasons why hair turns green, and learning how to fix ashy green hair color starts by figuring out why your hair got a green tint all of a sudden.

Swimming or Showering

If you shower with hard water, rich in minerals, those minerals will slowly build up on your hair. This is not a problem with the water quality; pure water from a well can be high in minerals!

Another reason for hair to turn green is the chlorine in swimming pools oxidizing with other minerals in the water (copper, iron, manganese). This is the same chemical reaction that causes copper roofs to become light green.

Using Toner Incorrectly

This is a problem mainly affecting blondes who like to dye their hair ashy, but in some cases, it can be noticeable in brunette hair. Blonde hair has mostly yellow pigments. Ashy dye has blue primarily pigments, which cancel the orange brassiness in the hair. But when you mix too much blue with too much yellow... your hair turns a pale, ghostly shade of green. If you are bleaching your hair at home, you must be very careful to choose the right toner for the level of lifting achieved.

Dyeing Problem

Many blondes who decide to dye their hair darker end up with murky green hair, and this is again a problem with balancing hair pigments. When you bleached your hair to blonde, you lifted most if not all of the red pigments from your hair. And this is great because otherwise, you end up with orange hair after bleaching, which is usually a big no-no.

However, if you decide to apply an ashy, brown dye to your hair to turn it darker later on, the blue ashy pigments will combine with the yellow in your hair to turn it into dark brown-green. Brunettes have enough red coloring on their hair to cancel that green and get a lovely neutral-colored brown hair, but you lifted that red pigment when you lightened your hair.

Bleaching Problem

Pigments and hair dye are funny things. Strange underlying pigments might appear if you used to have very dark dyed hair and try to bleach it. Blue-black dye, in particular, tends to lift swampy green or blue, but some semi-permanent dyes also do this. This is because green and blue pigments are often used to manufacture semi-permanent rainbow colors and nearly black permanent dyes.

Unless your hair is natural and untouched, always do a strand test and be prepared to have to re-bleach to get rid of the formerly invisible undertones. If your hair is very dark, choose a bleach for dark hair and toner that realistically will work with the end base color. Do not assume you'll reach a level 10 platinum on one sitting, and buy Wella T14 to tone it because you will likely need at least a couple of bleaching sessions.

What Color Neutralizes Green Hair?

We need to turn to color theory and the color wheel to figure out what color cancels green hair.

The color opposite to green on the color wheel is red, but hair is not usually a bright green color all over. You may have lighter shades of green which are neutralized with a warm purple-ish color, or more towards blue, which would be canceled with a blueish toner.

It depends on why you got green hair in the first place. Pool green hair is likely to be paler in color, whereas if you got green hair from bleaching dark hair at home, you might have more blue undertones.

How To Neutralize Green Hair?

If you don't want to cover your green hair with darker hair color, you will need to neutralize the visible green pigments. You will need a toner or a warm blonde box dye with an intensity similar to your current hair color.

Opt for a golden or warmer color, even if you don't like warm tones in your hair. The warmth will cancel the green and blue pigments that make your hair green without noticeable.

Why Did My Hair Turn Green After Dying It Blonde?

If you are trying to dye your hair ash blonde at home and end up with green hair, you aren't alone. It happens to many people attempting to dye brown hair blonde without bleach, as the toning step is incorporated into the lightening process.

Hair dyes are a mix of pigments, and ash blonde hair dye has a lot of blues to make a cool color. Blonde hair has a lot of yellow pigment. Blue and yellow make dirty green.

If you bleach your hair and then tone it, you need first to make sure your hair is light enough, with less yellow pigment. And you must also ensure that the toner you are using has just enough blue or purple to make your hair nice, bright, and ashy, instead of smurf blue or swamp green. Getting rid of yellow hair after bleaching is not a one size fits all solution.

If you use a single process hi-lift hair dye, you may not get the balance right and end up with green hair if the hair didn't lift enough or the ash pigments were too intense.

How To Prevent and Fix Green Hair After Dying Hair At Home

To prevent a blonde dye job from going green, you want to carefully balance the cool toning with the actual base color of the hair. This is easier said than done, but a good rule of thumb is avoiding a dye designed for lighter hair than your actual base color when toning or dyeing.

If the damage has already been done and your blonde hair has turned green by the time you read this, you will need to embark on a color correction process. This can be done in three different ways:

• Deposit pigment on top of your existing color to cancel out the green.
• Use clarifying home remedies to remove excess toner from hair until it reaches your desired color.
• Bleach the hair again to get to a lighter base level, and then tone the hair to the desired shade.

Color correction is an art form, as you will need to be very familiar with color theory and able to judge the balancing pigments accurately. If your hair is very green, you may be better off heading to a salon for a professional to look at it and customize the right dye mix and treatment.

Is It Just Blond Hair That Turns Green?

All hair colors can become green after the pool or lousy toning, but it's more noticeable in lighter tones.

The exception is the infamous shade of swamp green you can acquire if you dye blonde hair brown without filling in the red pigments beforehand. An ash brunette hair dye has many blue pigments, which, combined with the yellow in the hair, cause a very unflattering shade of swamp green.

How To Remove Green Tones From Brown Hair?

The best solution to green tones in brown hair is to add red pigments to the hair by using a protein filler before dying your hair brunette. If you went from blonde to black hair, heavily blue-based, you might need to bleach again to get to a more natural brunette shade.

You can also include reddish color depositing shampoos or masks into your routine to cancel the green without having to dye again.

How To Fix Blonde Hair That Has Turned Green

If your blonde hair has turned green due to hair dye, you will need color correction techniques to get the shade right. Thankfully it's not so difficult if you understand color theory.

Looking again at the color wheel, you want to add red pigments to your hair as red cancels green. But you don't want to add too much red, unless you want to become a redhead. The exact amount of red pigment and how to apply it to the hair will depend on your hair level, porosity and what end result you want.

For example, some people will choose to tone to get rid of green hair for a long time. Others will minimise hair damage by using a suitable color conditioner that deposits just enough red to get rid of the green tinge.

How Do You Get Green Out of Bleached Hair?

First, you need to assess why your blonde hair turned green. This will help you decide how to approach the problem and how to fix green hair correctly. We are into color correcting territory, so every solution will need to be 100% customised to your hair condition and color.

What To Do if Toner Turned Your Hair Green

If the reason for green hair is too much toner or toner that has too many blue pigments, there are two different ways to go about fixing it:

• Bleach your hair lighter and then tone again
• Use a warm toner to cancel the green
• Dye hair darker to cover the green

Can You Tone Green Out of Hair?

You can tone green out of hair, but you will be using a warm-toned dye instead of the usual brightening toners. This is the opposite of getting rid of orange hair after bleaching but shares the same technique.

This works particularly well if you have dyed your hair green before and are trying to bleach it back to blonde. Green and blue hair dyes can be very stubborn, and it's challenging to get them out of hair even after bleaching thoroughly. Don't forget that if you have ever dyed your hair black, you will also be in this situation once the bleach strips away most of it.
