That you can maintain a brighter color longer in those colors with purple shampoo because it helps to make sure unwanted tones don’t appear in your hair, like yellow tones.

Many different factors can damage the color of the hair dyed in those colors, like, for example, being out in the sun too long, using shampoos with sulfates, and even washing your hair too often.


  To avoid losing that color that you’ve worked so hard to get, you need to use purple shampoos that are designed for neutralizing those ugly tones, since purple is the opposite of yellow on the color wheel.

How long to leave purple shampoo in your hair depending on what you’re trying to do

Did you know that people originally used purple shampoo to keep grey hair a silver color?


Then, as platinum and ashy blonde colors became more popular, laboratories realized that it also works well for eliminating unwanted tones in bleached hair or hair that’s dyed light blonde.

Of course, white hair’s needs are very different than highlighted blonde hair, so you’ll need to use purple shampoo differently depending on what kind of hair you have. Let’s take a look at each possible case.


How long to leave the purple shampoo in your hair if you have platinum hair

before and after

If you have white hair, you’ve definitely come a long way. Maybe you’ve had to bleach your hair several times and use a platinum toner.

But, after a few days, some yellow tones might start to appear that aren’t anything like that white color you’ve been working toward. What can you do?


Use purple shampoo!

Any purple shampoo? NO!


 I recommend, and this applies to all of these different cases, a high quality shampoo. 

How do you know if a purple shampoo is of high quality?


If it has an intense, bright purple color, then it has a larger amount of pigments, which will ensure better results. And, you should also check to make sure it is sulfate-free.

Great, now you have your high-quality purple shampoo. But, how long does it take to work?


 If you have white or platinum blonde hair, 5 minutes will be more than enough. 

And you don’t need to wash your hair with the purple shampoo every day. Use it every other time you wash your hair, sticking to your normal shampoo the rest of the time.


How long does it take for purple shampoo to work if you have hair that’s dyed blonde or if you have blonde highlights?

As days go by, tones will start to appear in hair that’s been dyed blonde or hair with blonde highlights that aren’t exactly the tones you had in mind when you went to the hair salon. They’re usually yellowish tones that undermine any good bleach job.

That’s because of the effect that solar rays, chlorinated water, and even how often you wash your hair has on your hair color, because all of those things influence the pigments in the dye, causing it to fade.


When this happens, you can use purple shampoo, which will not only neutralize those ugly yellow tones but also make it so you don’t have to apply new dye so often.

 But, in this case, you should only use the purple shampoo once a week and leave it in your hair for 3 minutes.  


Now that you know how long it takes for purple shampoo to work, let’s talk about how to use it correctly.
