Blue Shampoo Turned My Hair Green, How do I fix my hair?

blue shampoo turns hair green

  • If blue shampoo turned your hair green, you’ve obviously left it on longer than indicated. Or you may have used it too often. So the first thing to do is to stop using it.
  • Then you should use a clarifying shampoo to remove the excess blue pigments, which are the ones that give blonde hair a greenish tint.
  • And once you remove the excess blue shampoo, start using it just once a week, leaving it on for only two minutes.

Do you look at your blonde hair and it’s greenish?

Does it have a dull green color?

Evidently, your blue shampoo is to blame. Well, poor shampoo.

What I mean is that  if your hair is greenish after using blue shampoo, you used it incorrectly. 


It’s like when you’re cooking and you pour in salt without tasting the food as you go. A good chef will always tell you that food should be tasted as it’s being cooked.  And if it lacks flavor, you can add more salt as you go.

Because once you overdo it with salt, the food will be inedible.


The same thing is more or less true with blue shampoo as with salt.

Blue shampoo should be used in just the right amount so you don’t overdo it. Because when you overdo it, your hair turns greenish.

But I must admit, if blue shampoo has turned your hair green, it will be easier to fix than if you’ve put too much salt in a meal. Because the food will inevitably end up in the trash can.

Since your hair can be saved, let’s start to understand what happened while you were using blue shampoo. Because it’s also important you understand what blue shampoo is for.

Why blue shampoo turns your hair green

cancel the orange tones

Blue shampoo is used to neutralize strident orange colors in colored or bleached hair. Many women even use blue shampoo on dry hair.

For example, if you bleached your hair a light brown 5 or dark blonde 6, it’s very common for orange tones to emerge. Why? The middle numbers of the color chart contain this shade underneath.

Orange can also turn up if you applied a 7.4 copper blonde hair color or any hair color with a 4 finish, which is an orange or copper shade.


When you started using blue shampoo, the pigments in the shampoo removed the orange, leaving your hair a more ashy blonde.

But, if the orange goes away and you continue to shampoo your ash blonde hair with blue shampoo, your hair will turn green.

Why is that?


It all comes down to an equation or mix of colors.

Your blonde (yellowish) hair + blue shampoo = greenish blonde.


And depending on how dark or light your hair is, blue shampoo will turn it a deeper green or lighter green.

  •  If your hair is dark blonde 6 or blonde 7 , blue shampoo will turn it darker green.
  •  If your hair is light blonde 8 or very light blonde 9 , blue shampoo will turn it light green.


Well, it’s time to relax, because I don’t want you to give up. What’s done is done and a solution must be found.

Woman, really, relax! The solution is simpler than you might think. Keep reading.

And the second thing you should do is buy a clarifying shampoo, which will help you remove excess blue pigments from your hair.

Why does a clarifying shampoo easily remove excess blue shampoo from the hair?

washing toner from hair

Because blue shampoo is not a permanent dye, i.e. you don’t apply it with developer or ammonia. Therefore, it doesn’t lighten or darken your hair.

It only works by neutralizing the strident colors that stick to the hair cuticles, which are the outermost part of your hair.

Therefore, the clarifying or detox shampoo will easily remove the blue shampoo.

How do you apply clarifying shampoo?


  • In the shower, wet your hair and wring it out.
  • Apply the clarifying shampoo from the roots to the ends and massage deeply.
  • Rinse your hair and reapply the clarifying shampoo from the roots to the ends again.
  •  Leave it on for 20 minutes .
  • Massage every now and then so that the shampoo can better penetrate your cuticles and remove the excess blue color. Observe the color of the foam. It will most likely be blue or green, and this means the clarifying shampoo is working.
  • Rinse your hair and apply conditioner to moisturize your hair.


In some cases, there may be traces of blue shampoo remaining. I recommend that you re-use the clarifying shampoo only after 15 days, to prevent your hair from drying out.


How to apply blue shampoo from now on so your hair doesn’t turn green again

In this case,  it’s always best to follow the manufacturer’s instructions . Because some blue shampoos have more intense pigments and should be used less frequently.

What I recommend is to find out how often you should use the shampoo on your hair. Because there’s nothing better than your hair to tell you how often it needs blue shampoo.

Some hair is more porous and quickly absorbs any product you apply. Other types of hair are healthier and absorb products less easily.

So, you could say that how often you should use blue shampoo is all about trial and error.

Also, think about this.


If blue shampoo turned your hair green, how often did you use it? How long did you leave it on your hair?

  • For example, if you used it twice a week and left it on for five minutes, what you can do from now on, is to use it once a week and leave it on for two minutes.
  • If after two weeks, your hair starts to get orange tones, you can increase the exposure time to five minutes, maintaining the frequency of use.


I don’t advise you to increase how often you use it. I find it a better option to increase the exposure times. You should always observe your hair and follow the manufacturer’s instructions.



Blue shampoo can turn your hair green if you use it more often than the manufacturer recommends.

To remove the green tone from your hair, use a clarifying shampoo and then adjust how often you use the blue shampoo.
