Can I mix 20 volume developer with purple shampoo?

  • It’s not a good idea to mix 20 volume developer with purple shampoo.
  • Mixing developer with purple shampoo won’t help you change your hair color, nor will it lighten it, darken it, tone it, or anything. I repeat: this mix isn’t good for anything, all it will do is harm your hair.

Stick with me just a few more minutes and I promise I’ll convince you otherwise.


It’s true what they say: Isaac Newton discovered the law of gravity thanks to an apple falling out of a tree.

But you’re not Newton, and developer and purple shampoo have concrete and already-established. They should be used based on the laws written by their makers.

Why mixing purple shampoo with developer won’t work for dyeing your hair

before and after

The reason is simple: purple shampoo doesn’t work for dyeing your hair.

Purple shampoo works for neutralizing yellow tones that can appear after bleaching your hair or for maintaining an ashy tone after dyeing your hair.


 If you intend to dye your hair using purple shampoo, you won’t get any results because it doesn’t contain the same amount of pigments as a purple dye. Plus, the pigments are different from those in purple dye. 

Pigments in dyes contain ammonia, which is what makes those pigments persistent enough to penetrate your hair fiber, while the pigments in purple shampoo don’t contain ammonia.


The pigment in purple shampoo is designed for depositing color on the exterior part of your hair, without breaking your hair fibers to make them absorb the dye. When you wash your hair with the shampoo, your hair fiber is more porous and that’s why it absorbs the pigment to neutralize the yellow color.

So, the dye penetrates your hair fiber because its ingredients make it more aggressive, while your hair absorbs purple shampoo without any extra stress.


If you want to dye your hair purple, you should buy a purple dye.

tone it down with conditioner

You can choose between lighter purples, using different semi-permanent dyes, such as:

  • Manic Panic: purple haze, ultra-violet, plum passion
  • Artic Fox: purple rain


And if you’re looking for a permanent dye, you can turn to the well-known, big brands, like:

  • L’Oreal Paris: the deepest purples are 16, 3.26 y 4.26
  • Wella Koleston: in this brand, purple is 66
  • Garnier Nutrisse: you can choose between darker purple 16 and lighter purple 4.62


Any of these dyes will change your hair color to purple without having to make mixtures that can irrevocably damage your hair.


Why mixing purple shampoo and developer won’t lighten your hair


Don’t insist on using dangerous mixtures!

I’ll repeat myself one more time: purple shampoo is very good for toning your hair after bleaching it or for preventing bright yellow tones from appearing in hair that’s dyed blonde.


 If what you’re looking to do is lighten your hair with a bleach bath, you should mix the peroxide with a colorless shampoo and not with a purple shampoo. 

Because since the peroxide gets rid of color, the second you use the purple shampoo mixed with peroxide in your hair, the peroxide will get rid of any remnants of color, including the purple.

That is why you should do a bleach bath with colorless shampoo.


 My recommendation is if you want to do a bleach bath, you do it with a colorless shampoo that contains nutrients like keratin. 


What do you need to do a bleach bath?

  • Colorless shampoo
  • 20 volume developer
  • Coconut oil


You can prepare a bleach shampoo that will lighten your hair a few shades without harming your hair using just these ingredients.

To make the bleach bath, you should get an empty shampoo bottle and mix half of a jar of 10 or 20 volume developer, half of the colorless shampoo and 10 drops of coconut oil.



  • Wet your hair and use the bleach shampoo on your hair, massaging it into your hair so it foams up.
  • Leave it in 10-20 minutes, keeping track of the process by checking on it every 5 minutes as your hair color changes.
  • Rinse with cool water and then use conditioner.


 Now, don’t abuse this product. A bleach bath is still a chemical process that can cause some damage in your hair, so you shouldn’t do it every day.  You can use it every 20 days, and you should do a deep hydration treatment on your hair afterward.


If after a bleach bath, your hair ended up with some yellowy tones, you can use purple shampoo to get rid of those unpleasant colors.

Replace your normal shampoo with the purple shampoo and you’ll see how the color changes with each wash.



  • Mixing purple shampoo with a 20 volume peroxide won’t lighten your hair, nor will it dye it purple. But, what it will do is weaken your hair to its breaking point.
  • If you want to have purple hair, choose a permanent or semi-permanent dye. And, if you want to lighten your hair a shade or two, do a bleach bath by mixing colorless shampoo with a 10 or 20 volume developer.

And please, use your creative side on things that won’t put your health or your hair at risk.
