Did Your Hair Turn Green After Dying It Blue? Here’s How to Fix It

When you decide to dye your hair blue, you have an idea of how it may look. However, many people dye their hair only to find it turned green.

If your hair turned green after dying blue, you don’t need to panic. There is a good reason why it happened and some things you can do to fix it.

Why Your Blue Hair Turned Green?

If you have dark hair to begin with, you most likely bleached your hair before dying it. Since bleached hair often looks yellow, it can cause your hair to turn green when you add blue dye to it.

When you dye your hair a dark shade, it will look perfect when you are done. Over the next few days, the color will lighten as you wash it. Eventually, the color will become so light that you will have to dye it again to get that same level of darkness.

The same is true for hair that has been dyed blue. You bleached your hair before you dyed it. So after you wash it a few times, the yellow of your bleached hair begins to show through. The tint of yellow looked at through faded blue will be green.

Fixing Hair That Turned Green After Dying Blue

If you are upset about the green tint in your hair, there are a few things you can do to get rid of it.

First, decide if you want to cover the green or if you want to try some different colors. You may also decide to get your hair back to the bleached tone so you can dye it a darker, more traditional color.

#1. Anti-Dandruff & Clarifying Shampoo

Although your instinct may dictate bleaching to see if the green goes away, bleaching your hair again could damage it since it removes so much moisture.

The easiest way to get back to that color is to wash it with an anti-dandruff or clarifying shampoo. The corrosive chemicals in it that help rid you of dandruff will also strip the dye.

However, it will not be an immediate fix and could take up to six washes to accomplish, so be patient.

#2. Baking Soda

You might try a baking soda treatment. Mixing baking soda with water and massaging it into your hair can strip away the dye. It could take a few times to get the desired result, but the method is proven.

Baking soda and dandruff shampoo can dry out your hair and cause damage. Be sure to condition your hair well afterward.

#3. Use a Toner

Using a toner can help to color-correct your hair. It adds tones to your hair that will help to cancel out the ones you don’t want. You should choose tones that are on the opposite side of the spectrum in the color wheel for the best results.

#4. Color Filler

A color filler will create a base for your hair, turning the yellow-bleached hair into a shade of blue.

Then, when your blue dye begins to fade, the color that shows through will be blue. This will save you a lot of embarrassment and help keep you from panicking.

#5. Dye Your Hair Again

The thing about dying your hair is that you have to keep doing it if you want to keep the look. If the color in your hair has faded enough to appear green, then dying it all over again could be your best option.

You might dye it the same shade of blue again, or you could try something entirely different.

Another shade of blue would cover the green well, but so would other colors like red, orange, turquoise, violet, or fuchsia.

Final Thoughts

It can be jarring to look in the mirror and see that the blue hair you were so proud of has started turning green. However, it is scientifically normal for it to happen. Don’t worry because there are quite a few things you can do to correct the problem and prevent it from happening again.


Here are some of the most common questions when your hair turned green after dying it blue.
