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. “When you eliminate too much yellow, it visually ends up darker and a lot of people don't want it to look darker,” she says.
If you use purple shampoo too often, you may notice a slight purple hue on your hair—especially if you have very light or damaged hair. If this is the case, try using purple shampoo a few times a week instead of daily.
How Often Should You Use Purple Shampoo? Purple shampoo is meant to only be used weekly or when your hair is looking brassy — not every day. Generally, you'll want to incorporate it into your hair care routine one to three times a week in place of your usual shampoo for color-treated hair.

Purple Shampoo
If your hair is on the yellowish, orange end of the spectrum, purple shampoo will fix it. Like blue shampoo, purple shampoo is another at-home option that's formulated to neutralize brassy yellow and orange tones in color-treated hair.

Purple shampoo is a cleansing toner that helps to keep your blonde and lightened hair looking fresh and vibrant. Its purple pigments draw out brassiness and neutralise those unwanted tones, keeping your colour cool and brass-free.
"Alternate your purple shampoo with a moisturizing shampoo," says Wiley. "Depending on how brassy your blonde hair is, you won't need to use the toning effects every wash, and it is important to add moisture and strengthen hair during the color process to keep hair healthy and strong."
“Purple shampoo does not cancel out orange so if the hair has any orange or yellow orange tones in it, the purple shampoo would actually make them warmer depositing red into the hair.”
It's important to note that the pigment in purple shampoo isn't a lightener or hair dye but a gentle toner that works overtime. So it can't darken your hair or make it any lighter. For this reason, if your hair tone is too dark, it won't make it any brighter.

DOES PURPLE SHAMPOO DAMAGE HAIR? The cool violet pigment in purple shampoo won't damage hair, but if you leave it on strands too long, those purple pigments will take their job a little too far and could turn tresses a purple-violet colour.
Your lightened blonde pieces will have absorbed some of the base break colour. Highlighted hair is often porous and can take on ash tones heavily – the hair then appears greyish or sometimes even silver.
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.
