A chemical reaction is the cause of discolouration in human hair that has been processed to blonde. This chemical reaction can turn blonde hair into pink or brassy yellow hair.

Learn more about why this happens and how you can fix it yourself.

What Brassy Means

To understand how discolouration in blonde hair can occur, we must first understand what “brassy” means.

Brassy refers to the colour of blonde hair that has a yellow or orange tone. It is an undesirable colour as it makes the hair look dull.

The usual cause of brassiness is overprocessing or the use of hair dyes or bleaches containing peroxide.

Over-processing makes the hair dry, brittle and damaged, which makes it less elastic and more prone to breakage. So, when the hair is placed under tension (as when the hair is worn up in an updo), it breaks.

Brassy hair is easy to diagnose because it usually appears dull and yellowish. If it is more orange in tone, it is called “olive brassy”.

Why Your Hair Turns Brassy

Bleached hair is more porous and has a more porous cuticle. This means that it can trap more of the peroxide deposit.

Sometimes, it may even result in a greenish hue in blonde hair, especially if the hair was bleached repeatedly.

Over-processing and frequent use of bleach or tinting can also result in broken and damaged hair.

This is because bleach and tinting treatments involve the use of chemicals which are extremely harsh on your hair.

If your hair is subjected to repetitive bleaching, it will get damaged. This is because the peroxide in the chemicals causes the follicle to break down.

When this happens, the hair becomes more porous.

Can I Fix This at Home?

In many cases, a person can actually get rid of brassy hair in blonde extensions. However, there are several things you must remember.

First, you must make sure that you will not repeat the same mistake. You should not use bleach or tint your hair again. It is true that you can reduce the brassiness by applying toner. However, it is not recommended.

If you want to achieve that perfect blonde hair colour, you must make sure that you will be doing it the right way in the future.

Second, you must be careful with the shampoos and conditioners you use. They should be quality products and have minimal ingredients.

Finally, you should use a good shampoo and conditioner. A good conditioner will also offer some coverage for your hair. It will also help you remove any impurities on your scalp.

What Not to Do with Your Extensions

Although you can dye your extensions to a lighter shade of blonde, it is not recommended. Your hair might come out dull and yellowish.

If you have a tendency to have brassy hair, it is best to dye your hair to a lighter shade of brown. This is because it has less amount or no peroxide in it.

As your hair will keep changing colour, it is recommended that you not dye it jet black. This is because jet black hair has a high amount of peroxide, which can damage your hair.

You do not need to apply toner to your hair. Doing so will only damage your hair. Removing the brassy tone will take a lot of time and patience.

You must remember that the result of your dyeing will depend on your scalp and hair condition. If you have been using harsh hair treatments, your hair will be more porous. This will cause your hair to turn brassy more quickly.

Steps to Turn Brass to Ash

If you have already decided to fix the brassiness of your blonde extensions, here are some easy steps you can try:

1) Make Sure Your Hair Is Healthy

Brassy hair is usually caused by bleach. If your hair is damaged, it will turn dull yellowish after a few washes. This will make your hair appear brassy and yellowish.

If your hair is damaged, all you need to do is to use a good quality, moisturising shampoo and conditioner. By using it regularly, you can repair your hair and make it healthy again.

2) Use Blue Shampoo

Shampoos that remove brassy or yellowish tones are known as “blue shampoos”.

Most blue shampoos use greenish or blueish shampoos. They contain ingredients that can counter the yellow tinge in blonde hair.

Some people also recommend adding a few drops of blue or green food colouring to your shampoo. However, there are worries that too much colouring can cause your hair to look green.

3) Work It in Your Hair

Brassy hair can be removed using the shampoo and conditioner that we recommended above.

After applying a generous amount of shampoo to your hair, you should gently massage it into your hair. This will make sure that all the shampoo gets into your hair.

You should repeat this several times until you have covered your whole head.

After washing your hair, you should apply a good conditioner. Let the conditioner sit on your hair for about 5 minutes before rinsing.

4) Rinse

Once you have washed your hair, you should rinse it thoroughly. This will make sure that all shampoo and conditioner has been removed.

Make sure that you do not squeeze water from your hair. Instead, you should gently apply pressure on it until it is all out of your hair.

This will ensure that your hair remains in good condition.

5) Condition and Dry

You should pay particular attention to your hair ends when using a hairdryer. The ends will take on the most damage and dullness.

If you want your hair to remain silky, try to get a hairdryer with a cool air setting. However, you should avoid making your hair too hot. This can cause the cuticle to become rougher and more prone to damage.


Brassy hair can be a nightmare for anyone who is hoping to achieve almost platinum blonde hair. You just have to make sure that you keep your hair healthy. This will ensure that your hair will not turn brassy or dull easily.
