What is purple shampoo?
Purple shampoos contain crushed violet or purple pigments.
They are meant to neutralize or get rid of brassy or yellow tones in the hair.
If you have turquoise or blue hair that is turning green (it is because of the yellow undertones), then you can use purple shampoo to neutralize the yellow so that your hair remains turquoise for longer.
Purple shampoos do not fade color, in fact, they enhance blue colors and help hair retain more blue.
What does purple shampoo do to green-dyed hair?
Purple shampoo has no visible effect on green-dyed hair.
If you use a highly-pigmented purple shampoo, it may brighten your hair a little but the effects aren’t worth the time and price.
If your green hair is becoming more yellow-toned or faded, then go in with a blue/aquamarine dye over your green-dyed hair to help your green hair retain its tone.
So, if you are looking to make your green hair more vibrant and retain the correct tone (and get rid of yellow tones), you can add a little bit of aquamarine dye (I recommend this aquamarine dye by Arctic Fox) to a bowl of leave-in conditioner and then leave it on your hair for 30 minutes and then rinse it out.
This aquamarine dye should work beautifully to help your green hair look more green and vibrant.
You can even see a video here on how this girl dyed her already green hair with aquamarine to help her hair look much more vibrant.
