Are you thinking about applying purple dye to your green hair?


Then it’s vital to be clear about why you want to do this because your objectives will determine the results.

I can tell you in advance that:

  • If you apply fantasy purple dye to your green hair, your hair will end up being purple.
  • If you want to dye some green tones of your hair that have been dyed ash-colored, you should apply purple toner, because you will just neutralize those greens, and your hair won’t be purple.


Of course, this is the big picture because behind each of these statements is an explanation.

And you must understand the difference to achieve what you’re looking for by applying purple dye to your hair.


Maybe to understand these very different situations, I should first ask you why your hair is green.

  • Is your hair green because you applied a fantasy green dye?
  • Or do you have some ashy-green sections that have appeared after many years of dying?

Because from there comes the difference, the solution, and the results.


Therefore, so you don’t make any mistakes, stay tuned because I will tell you:

  • How to apply dye to your green hair so that it becomes purple
  • How to tone the green parts of your hair with purple

As we covered in the beginning, if you apply purple dye to your green hair, your hair will end up purple. And this always happens when we’re talking about fantasy color dyes.

What do stylists mean when they say fantasy color dyes?


  • All shades beyond the conventional color palette. Colors like green, electric blue, fuchsia, or purple.

Have you ever seen all those hairdos on Instagram where the colors remind us of mermaids or the realm of unicorns?


Those colors have resulted from applying a fantasy dye.

Do you have a friend that changes her hair color every 15 days?


  • She’s most likely using these types of dyes because they’re very easy to apply, they don’t contain peroxide, and their consistency is gelatinous.

And because they don’t contain peroxide, they only settle on the cuticle’s external part, so they disappear gradually when you wash your hair.

Once you apply the fantasy shade that you picked, it lasts for approximately two to four washes.


  • If you ask me what the best fantasy shades are, I will tell you two things: there is a wide range of pastel and vibrant colors available, and none of them will damage your hair in any way.

Because the color will fade each time you wash your hair without needing to remove it by bleaching as with other types of dyes.

But what happens if you want to change colors?


 You don’t have to make any prior arrangements, you only have to apply the new tone, and you’re set. 

Because if you have the fantasy dye as your base and apply a new color that’s also a fantasy dye, you won’t have any problem.


While I’m writing this, I’m reminded of Anna, one of my clients who came to apply a green dye to her hair about two months ago. Of course, I applied a fantasy dye.

I was surprised that twenty days later, she returned to the salon and asked me if I would bleach her hair.


I asked her why she wanted to bleach it, and she said that it was because now she wanted to have purple hair.

  At this moment, I explained to her that it’s not necessary to bleach your hair—simply applying a purple dye to your hair will be enough to cover it up. 


After picking her customized purple dye, we covered her green hair with it, and the result was amazing.

Her green hair had disappeared completely, and it had given way to an intense purple that complemented her huge green eyes.

Do you want to cover your green fantasy dye by applying purple?


Do it without hesitation because the purple tone will completely cover the green color!

  • You only need to buy the purple fantasy dye and apply it, but I also recommend that you wait until the base tone has settled, in this case, the green, so that the purple turns out much better.
  • And if you’re not going to go to the salon to change your green shade, you should buy the same brand of dye because you’ll already know how to apply it and the time it takes for the dye to work.
  • The purple shade will cover any green tone you may have as a base, whether it’s a light green or dark green.
  • Lastly, remember that it’s always recommended to start applying the dye to the long part of your hair and then afterward to the new growth because, in this way, your hair will absorb the pigment evenly.


Now that we’ve clarified that if you dye your green hair with purple fantasy dye, your hair will turn out purple, let’s go over the other alternative.

Do you put gray tones in your hair?


If so, then you’ll notice that if you always apply the same tone, it’ll get saturated, and you’ll end up with greenish colors.

You can slightly tone your hair to neutralize these greens by applying purple toner. Only in this case, your hair will not end up being purple.

Do you want to know why? Keep reading because this technique has its secret tricks.


How to dye your green hair with purple toner

I’m going to start explaining this technique by telling you about one of my clients’ example.

Her name is Sylvia, she’s 65 years old, and for a long time, she’s come to the salon to dye her long hair an ultra-ashy blonde color.

If you have gray hair, you must retouch your color every three weeks.

As time passed, some parts of her hair were becoming green, and as a result, she entered the salon feeling desperate one day because her hair had started to look green. And that scared her.

Of course, if you don’t want to have green hair, anyone in her situation would get scared.


  • I explained that she shouldn’t lose hope, that this was a logical problem, seeing as by applying the ultra-ashy blonde, the color had become saturated, and it had started to look greenish.

Then, I explained that what we could do was apply a purple toner to her hair. She looked at me as if I were from outer space, suggesting that we go on a oneway trip to space.


  • Of course, she thought that her hair would end up being purple. But when I told her that the toner would just simply take out the green, or that’s to say, it would neutralize it so that her hair would look as blonde as always, she calmed down.

Even so, while I put the purple toner in her hair, I could tell she was very nervous, but after I washed out the toner, her smile returned to her face. And she also was relieved because the green was already gone.

And, of course, the purple wasn’t there either.


  •  If you are like Sylvia, you can apply a purple toner to fix green tones. 

That said, you must be very careful if you want to dye your hair using purple toner because your color is becoming too ashy green, given that your hair could end up being purple.

Toner is a pigment that is used to neutralize undesirable colors, like green or orange. And it can always be applied after dying or bleaching to take out these undesirable tones.



Now you know what happens if you apply purple dye to your green hair.

  • If you want to cover your green hair with purple fantasy dye, your hair will be purple.
  • If you want to neutralize the greens after applying an ashy tone, you can use purple toner to get rid of these greens. And your hair won’t end up being purple because it’ll just simply neutralize the green.


So, which of these situations is most like your own? Why do you want to apply purple dye to your green hair?
