What happens if you use toner on purple hair?
It totally depends on what you are trying to do. Going with the colour wheel, depending on the purple it would be yellow, orange or even green with certain purples. This doesn't mean if you have bright purple hair a blonde dye will “cancel” out the purple.
What cancels out purple hair color? If the purple in your hair is mild, it has a blue tone, thus an orange toner is recommended. If your purple hair is dark, it has a stronger purple tone and should be toned down using a yellow toner.
Leaving toner in your hair can take as quick as a minute but should not exceed 45 minutes.
If the purple residue in your hair is pretty light, a clarifying shampoo may do the trick! Apply the clarifying shampoo to your hair just like regular shampoo, lather it up for a few seconds with your fingertips, and rinse it out. Repeat this 2-3 times to make sure you get rid of the tint.
Ashy tones occur in hair color when there's too much of a cool or blue pigment in a dye or toner. Think of it as editing an image – if you cool down the coloring of a photo, it often turns very blue or green. The same happens with hair – if you have too much cool pigment, it saturates the hair with a blue/green tone.
On the color wheel, purple is the opposite of yellow, which is why purple pigments cancel out brassy, yellow tones. When you get your hair professionally colored at the salon, hairstylists often tone hair to neutralize brassy yellow and orange tones on bleached hair.
Mix some Vitamin C in your clarifying shampoo, let the mixture sit in your hair for 5 min, and then rinse it out. Vitamin C is an acid which means that it has the strength to help break up semi-permanent hair molecules, in order to get them to fade faster.
If anything, purple shampoo may make your hair temporarily slightly darker. This is because the inky purple pigments found in purple shampoo are a darker color than the shades of yellow in blonde hair.
Use toner after dyeing your hair.
To help remove certain pigments, like if your hair has too much red or brassiness, you can use toner to even out your dye job or adjust the color. Toner can sometimes be used after a bad or undesirable dye job. It can't change your hair color, but it can even out your shade.
How Often Should I Use Purple Shampoo? Keep in mind that purple shampoo does not replace your regular shampoo and should only be used once or twice a week. Doss warns that there is such a thing as too much purple.
What happens if I put blonde hair dye on purple hair?
No matter what you do, it will fade, because purple hair dyes are semi or demi-permanent, not completely permanent.
No, you don't need toner. Toner is not a magic fix or cure all for a poor bleach job. Add in that most toners have a purple base to counteract the yellow in hair after bleaching, and you are simply using products you don't need if you are also dyeing it purple.
