How long to leave purple shampoo in your hair?

Between 3 and 5 minutes, depending on the brand of the shampoo you choose and the results you want to achieve.

If you leave the shampoo in your hair for longer, you could end up with purple hair.


Hello to all my beauties.

How is your week looking?


Mine is great.

I´m thrilled.

My kids went back to school after summer vacations

My husband is on a business trip

And I’m home alone.

What a delight!


I love my family, don’t get me wrong, but it is nice having some peace at home every once in a while.

The noise is beautiful and all, but enjoying silence at least once a year is divine.


Today, I want to talk about a topic that has been coming up a lot lately in your questions.

How much time should I leave toning shampoo in my hair?


Some say 20 minutes.

Others 3 minutes.

But what is the truth?


 At the end of the day, it’s important that if you leave toning shampoo in your hair for longer than necessary, you could end up with horrible green hair. Or purple.  

Without going too far off-topic, the other day, a very distressed girl contacted me.

was left more time than necessary

“Carina, I made a huge mistake,” she said to me.

“ I left the purple in my hair for 20 minutes, and now I have this horrible tone. It’s not blonde, not green, nothing.

I’m so sad because I like how the blonde looked on me. Also, dying my hair cost an arm and a leg because I went to a well-known salon in my city.

I don’t know what to do. I hope you can help me.”


 What happened to this girl could have been avoided if she had only left the toning shampoo on her hair for just the necessary amount of time. 


So, today, I’m going to tell you exactly how long you should leave the shampoo on your head so that what happened to this girl doesn’t happen to you.

Let’s start with the most important.

Five minutes or Twenty?


The first thing I’m going to tell you may seem obvious, but a lot of people pass it over.

You have to read the instructions on your shampoo.


 Each shampoo has a series of instructions on the label. I recommend that you read them attentively before starting to wash your hair. 

This is fundamental because even more than what I can tell you, each toning shampoo is different. Each shampoo has a percentage of color pigments that are very different from others. Because of this, it’s essential to read the instructions.

That is on the one hand, but also, there’s a second variable to keep in mind.


Each hair has a different color objective. So, maybe you need to leave the shampoo on your hair for 2 minutes, and your friend needs to leave it on for 5 minutes.

Maybe your friend only needs one wash to get the desired results, and you need three washes.


How long should you leave on the shampoo according to the brand?

There are lots of brands of toning shampoos. Some of them are more known than others. Also, you have to keep in mind that the brands vary a lot between one country and another.

Commenting on all of the toning shampoos would be impossible.

I’m only going to talk about the toning shampoos that I have used at some point and that I always recommend to my clients at the salon. Let’s start with one of my favorites, Shimmer Lights.


  • Shimmer Lights clearly says in its instructions that you should leave it in your hair for between 3 and 5 minutes.

  • Joico Endure color, another of my favorite toning shampoos because it doesn’t have sulfates, also says between 3 and 5 minutes.

  • Joico Color Balance is another popular purple shampoo these days. The shampoo’s instructions recommend leaving it in your hair for between 1-3 minutes. Note that here we have the first difference in respect to the first two shampoos that we saw. That is why I said it is crucial to read the instructions of the shampoo before using it.

How often should I use a purple or blue shampoo?

I emphasis is always little by little.

 I recommend to start by using the shampoo once a week.  You can always use it later, but to start, it doesn’t make sense to risk ending up with a hair color you don’t like because you rushed through things. Another thing.


To evaluate the results of the shampoo, let a few days pass. A lot of times, the color takes a bit to set in. I’ll tell you a story that happened a few days ago.


A girl came to the salon with half purple hair; it was a horrible color. Why would I lie to you?

It wasn’t purple, nor blue, nor blonde, nothing.

“What happened?” We asked.

I washed my hair with a purple shampoo two days in a row. After the first wash, I noticed that I still needed a bit more to get to the tone that I wanted. So the next day, I rewashed my hair with the shampoo. Big mistake.

When I got done trying my hair, I discovered that my hair had turned this ugly color.


What is the moral of the story?


Use toning shampoo little by little. To start with, once a week is sufficient.


Update: Can you leave the shampoo in your hair for 20 minutes?

I keep reading comments from people that leave the shampoo in their hair for 20 minutes or a half an hour.

If you have experience using this type of shampoo, and it has given you good results, it’s perfect.


But for people that use the shampoo for the first time, I don’t think that it’s a great idea to leave the shampoo in your hair for a long time.

In any case, start with the recommended time by the manufacturer, and then as you wash, you can increase the time.

Leaving the shampoo in for 20 minutes in the first place is too much. It’s like playing with fire.


Do you like to play with fire?

If you don’t, start with 3-5 minutes and then increase the time if it’s necessary.


Conclusions and one last tip

Almost all toning shampoos tend to dry out hair, so I recommend that after washing your hair, you should apply a hydrating mask or a little bit of coconut oil.


Do you have any doubts?

Did you buy a toning shampoo and you don’t know how long to leave it in for?

Leave your question for me in the bottom section for comments. These days, I have a lot of free time, as I told you before. I’m going to try to respond to each one of the questions.

I do ask a favor of you. Before leaving a comment, read the previous questions because a lot of times, you all ask me the same question over and over again.
