Could I just put it in my hair and sleep on it to make it more effective? 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.
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.
Unless you have white hair or gray hair, you shouldn't leave the purple shampoo on for longer than 15 minutes at a time. If you're already leaving the shampoo on for less than 15 minutes and you're noticing a purple tone, then try leaving the product on for even less time.
The violet pigment in the purple shampoo will not damage your hair; however, if you leave it on your mane for too long, those purple pigments will handle their job a little more effectively and could turn your hair into a purple-violet color.
If you leave the toner processing for too long, you might end up having damaged hair with unwanted purple or blue shades.
There's two reasons why your hair is still brassy after toning or colouring. Either the undertone of the toner/colour is wrong, or the product is too light for you.
The short answer: No! People have been trying this technique because your hair will absorb more of the purple pigment when it's dry.
The truth is purple shampoo is not going to make your hair any lighter or brighter. Purple shampoo is meant to color correct any yellow tones.
This is were the over using it can cause problems. "You want to stop using it two weeks before any lightening service. The purple shampoo can cause build up making the hair look dull and darker if overused." This makes the lightening process more difficult to create a seamless blend.
A purple shampoo will not dye your hair but if you leave it on for too long you could find yourself with a little lilac staining. It's easy enough to get rid of – just wash your hair with a clarifying shampoo to reduce the tint!
Too Much of a Good Thing: Purple Shampoo Left On Too Long
You can, in fact, over-tone your hair. Leaving purple shampoo in your hair for an hour or more can cause your hair to look dull and lifeless. To leave purple shampoo for more than 10 minutes is already too much.
Purple shampoo only works on light-colored hair, so anything from an ashy blonde, to grey/white hair.
Let the shampoo sit on your hair for 2-3 minutes if you're a natural blonde or 15 minutes for brassy color-treated hair. For gray or platinum hair, wait 30 minutes. Rinse out the shampoo thoroughly with cool water and follow with your favorite conditioner. Use purple shampoo once a week to maintain your hair color.
We've all wondered whether you can put purple shampoo on dry hair at some point, so we're here to set the record straight: toning shampoo should only ever be used on wet hair!
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.
Because it does not contain an ingredient that will chemically change the color of your hair, purple shampoo cannot truly lighten hair. If anything, purple shampoo may make your hair temporarily slightly darker.
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.
Purple shampoo cannot lighten or darken your hair color. However, if you leave your purple shampoo on for too long, you may notice that your hair has a slight violet tone. This is more common with those that have silver and white hair colors rather than warm blondes and slightly darker hues.
"But if you have been in the sun or feel as if your tone is too brassy, use purple shampoo at every wash until you get the desired results, then use once every third wash," she explains. Alternate With Moisturizing Shampoo: Alternate your purple shampoo with a moisturizing shampoo," says Wiley.
“A common misconception is that it is thought to make the hair brighter,” says Jamie Park (@hairbyjpark). “When in reality it's toning the yellow [brightness] and bringing it to its natural state—which can appear darker than yellow.”
Yes, purple shampoo could be making your blonde look darker — but don't worry, it's fixable.
What Is Purple Shampoo for Brown Hair? Purple shampoo for brown hair is the same product as purple shampoo for blonde hair. The color purple is used because purple sits across orange on the color wheel, so purple hair treatments will neutralize any brassy hair tones and help your strands look fresh.
Purple counteracts yellow, blue counteracts orange. They are opposites on the color wheel, so that's why. So if your hair has an orangey hue, the reality is, purple shampoo won't work.
First things first, we want to let you in on a secret — there is no difference between silver shampoo and purple shampoo. Just like purple shampoo, the term silver shampoo refers to a pigmented shampoo that's purple in color and helps neutralize brassy, yellow tones in blonde and silver hair.
