Unless the shampoo is specifically designed to be used as a daily toner, applying purple shampoo every time you wash your hair is typically discouraged because it can begin to eliminate too much yellow from your hair.
If you leave purple shampoo on for too long, you may find yourself with a little lilac hue. This color is not permanent and is more likely to happen if you have very light blonde hair or if your hair is dry and damaged. To remove the purple hue, switch to regular shampoo for your next few washes.
Purple shampoo is for already bleached hair, so if you're hoping to lighten brown hair with purple shampoo, you'll be disappointed. This is all down to the fact that purple shampoo isn't lightening. Instead, it brightens blondes by canceling out yellow tones, which just happen to be opposite purple on the color wheel.
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.
Don't use purple shampoo if you've got orange tones in your hair. You'll need a blue shampoo to cancel those out. Do ease into purple shampooing. Before using it at full strength, dilute it with your regular, normal shampoo – 1-part regular shampoo to 2 parts purple shampoo should work fine.
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.
You'll leave the shampoo on for 5-15 minutes before rinsing with cool water if your colored hair has been recently dyed or is discolored. If it's your first time trying purple shampoo, experiment with leaving it on for only 5-10 minutes before washing it out.
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.
If you find yourself asking, will purple shampoo fade red hair? Don't worry, it's perfectly safe. This hair care product will only help to tone your hair color, not fade it. In fact, it can actually help to neutralize unwanted yellow and orange tones as your red hair color starts to fade.
Zoe's answer: Leaving purple shampoo in your hair for longer than the recommended time is not always a good idea. The longer you leave it, the more pigments will be deposited on your hair and they could even stain it permanently.
Others may be too weak, meaning they need 10 minutes or more to make a noticeable difference to brassy tones if they manage to do anything at all. However, we've created the 'Goldilocks' of purple shampoos; a product with just the right level of purple tones, which takes 3-5 minutes to work its magic on brassy strands.
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.
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.
Purple shampoo works the same way to eliminate brassiness on brown hair as it does on blonde. It helps to prevent color fade, while emphasizing shine, keeping brown hair vibrant and rich. Using purple shampoo on brown hair regularly will take out any unwanted warm tones in your strands.
Purple shampoo can be used as a regular shampoo, or as an intensive treatment by applying it generously to dry hair. It won't affect, or damage brunette hair, but it can leave a lilac tint on light hair if left on too long. Always rinse, and follow with a moisturizing conditioner.
“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.”
Saying that, it does lather and in turn remove some build up from the hair, but I would advice you wash your hair with a normal shampoo first before purple shampoo, especially if you find your hair needs washing daily or hasn't been washed for a couple of days.
Purple shampoo is purple colored shampoo that distributes purple pigment to neutralize brassy, yellow tones. Purple is used because, if you take a look at the color wheel, it is the direct opposite color of yellow. This means purple and yellow cancels one another out.
For best results, use a purple conditioner after rinsing with your purple shampoo. You may want to wash hair with your purple system twice to thrice a week, depending on your blonde level.
Unfortunately, orange roots from bleaching will not fade to your desired color on their own. You can't hope that the orange will fade over time. The only way to get rid of orange roots is to color correct the unwanted shade. You can do this by using a toner or pigmented shampoo.
What Is Brassy Hair? Brassiness in hair is the unwanted warm tones that appear in colored hair. This is typical for people who have dyed their hair from brown to blonde or platinum. The reason the term is “brassy” is because of the color the hair turns when orange and red tones show up in strands.
If your hair is orange, you'll need a blue toner. Try a blue shampoo to tone the brassiness and get rid of the orange. This color toner is commonly needed for darker hair.
