  • Why is it so important that you use purple shampoo from the first washes after coloring?

To avoid tears and suffering.

Let me tell you a story.


Today Lili came to the salon. She always visits me for her balayage maintenance.

She needs to touch up the color of her golden curls every four to five weeks. However lately, Lili visits me every two weeks.


I started wondering why. I asked if she had followed my recommendations to wash her hair with purple shampoo from minute zero. I mean from the first wash, 48 hours after coloring her hair.

Her gaze went down to her cell phone as if she was looking for the answer. I understood that she was embarrassed because she had never done it before.

She had waited for 48 years but used her usual shampoo for the first wash.

So, the balayage work I had done in the salon started going down the drain only two days later.

Do you know why?


 Because traditional shampoos contain sulfates that wear down the color. 

Sulfates are detergents that wash pigments out of the hair fiber. Well, not just pigments. They also strip the hair of moisture.


If Lili had used the purple shampoo from the first wash after balayage, she would be visiting me at the salon every five weeks instead of two.

Do you realize how much money she would save in maintaining her color?


Also, and to be honest, nowadays you can get affordable quality purple shampoos quickly, and easily. It’s one of the advantages of globalization.

In other words, there are no excuses.  You already know that you should use the purple shampoo 48 hours after coloring your hair and from the first wash. 

Do you still have doubts?


Don’t worry because today I’ll tell you:

  • Why it is vital to use purple shampoo from the first wash on colored hair
  • Which purple shampoo to choose according to the needs of your hair

Why it’s vital to use purple shampoo from the first wash on color-treated hair


The short answer is to make your color last longer.


The long answer has to do with chemistry, that hated school subject.

You see, all hair products contain different elements.  Until some years ago, no one read the labels of such a basic product like shampoo.  People would buy the first one they saw on the supermarket shelf.


However, times have changed. It has to do partly with marketing and partly with advances in hair beauty. Thank goodness, for some time we can differentiate between sulfate and sulfate-free shampoos.

We already said that sulfates are detergents. Therefore they eliminate the artificial pigments of the dye and dry out the hair fiber.


Also,  the hair industry went a step further and invented the toning shampoo. One of its great exponents is the purple shampoo. .

It is a great discovery because it doesn’t only remove the pigments of the hair dyes. It also extends the life of the color because it neutralizes the orange tones in blond hair.


It means that every time you wash your hair, you add pigments, and your color remains intact for longer. Also, your hair fiber will be healthier since toning shampoo contains no sulfates or parabens.

Now, you shouldn’t leave purple shampoo to the last minute.


You should use it from the first wash after coloring your hair.

two days after coloring

Remember that you shouldn’t wash your hair for at least 48 hours after any coloring technique. That’s the time it takes for the pigments of the dyes or the toner to settle in the hair fiber.

There’re several purple shampoos on the market. Many of them are for frequent use.


Now, don’t get confused.

Frequent use doesn’t mean you should wash your hair every day with purple shampoo.  It means you can use it every time you wash your hair, which will be every three to four days. 

Which one to choose? There are many options.


Which purple shampoo to choose according to your hair’s needs

  • If your hair is very frizzy, choose MATRIX TOTAL RESULTS SO SILVER. It contains moisturizing agents to tone your hair and decrease frizz.
  • If your hair isn’t very porous, I recommend FANOLA NO YELLOW. Why? Because its pigments are very strong. If your hair is very porous, it’ll absorb them quickly and you may run the risk of ending up with lilac hair.
  • If your hair is very damaged and dry, I recommend L’OREAL EVER PURE purple shampoo and conditioner kit. In addition to adding pigmentation, it’ll moisturize your hair.


Apart from washing your hair with purple shampoo from the first wash after coloring, is there anything else you can do to extend the color?

Yes, and that’s what I’ll talk about next.

Now you’re aware of the importance of using purple shampoo from the first wash. Let’s go over other care products you can include in your color maintenance routine.


  • Don’t wash your hair every day

Elementary, Watson! Frequent hair washing leads to excessive color fading due to the chlorine in the water, the products you use, and the blow-drying. Ideally, wash your hair every 48 to 72 hours.


  • Don’t use sulfate shampoo and conditioner.

They’re very corrosive to color and hair in general. So, they’re banned from your bathroom medicine cabinet!


  • Wear your hair lose a few hours a day

This is very important. Tied or tied back hair prevents the hair fiber from breathing. So, it accumulates toxins that are corrosive to the hair color because they adhere to the hair fiber washing the pigment. Take the opportunity to let your hair go while you sleep, even if it’s just a few minutes.


  • Don’t overuse heat tools

Every time you run the flat iron or use the blow dryer, your hair gets dehydrated. When it dehydrates, it loses water and the dye pigments.

So, since you’ve spent a lot of money on coloring your hair, it’s best not to abuse the flat iron or blow dryer.



To keep unwanted tones away from your blonde-colored hair, you should use sulfate-free purple shampoo from the first wash after coloring your hair.

It’ll help you to keep your color longer and protect the pigments. Also, as it’s sulfate-free, it won’t wash them out and will give your hair extra hydration.
