Because they want to test out the latest hair care fad, or they’re curious about a particular product their friend swears by. And one such product is purple shampoo. Is purple shampoo bad for your hair?

There is no side effect on records of purple shampoo for hairs. The purple and violet color will not hurt the structure of your hair. But if you leave it for a long time, strands can catch the shade of purple shampoo. 

But purple shampoo comes along with some drawbacks too. And this guide, we will compare the good vs. bad and then decide whether it is suitable for your hair or not.

What is purple shampoo?

Purple shampoo is a helping hand for blondes that tones down brassiness and keep yellow hues at bay. It does this by neutralizing your hair’s orange and yellow undertones, leaving you with a cooler, more ashy blonde.

Purple shampoo contains two primary pigments: Violet 2 (CI 60730) and Blue 1 (CI 42090). The combination of these two pigments gives a shade of purple, which is why it’s called “purple shampoo.” And if you’re thinking, “Why would I want to put purple in my hair?” don’t worry — the pigments are very fine and won’t leave your hair looking purple.

How does purple shampoo work?

The primary way that purple shampoo works are by counteracting your hair’s brassiness. When your hair is lightened, the cuticle of each strand raises slightly. This raises the pH levels of your hair, which also turns your locks yellow or orange.

The pigments in purple shampoo target to lower the pH levels of your hair and close the cuticle. This helps preserve the blonde color in your hair and gives it a cooler, more ashy tone.

Is purple shampoo bad for your hair?

I can do a long and in-depth analysis of this question, but, ultimately, it is impossible to give a definitive answer. So, I have decided to sum up the pros and cons of purple shampoo to help you make your own decision.

The main concern regarding purple shampoo is that the purple pigments can deposit onto the hair. And this deposition can lead to dryness, brittleness, and even discoloration. But is it really, as people assume?

Yes, it can happen but with a condition. The purple pigments in the shampoo can only deposit on the hair if you don’t wash it earlier and delay washing it for days. In addition, purple shampoo can also cause your hair to turn slightly lavender if you have very light hair color.

And another thing is that by being smart with purple shampoo and not following the over-usage of it, you can use it as a toner to neutralize brassiness in hair.

So, purple shampoo is not completely bad for your hair. It has some benefits too. But over-usage can leave your hair dry, brittle, and discolored.

Will purple shampoo dry your hair out?

Yes, it is true if you don’t follow the rule of moderation and cross the line of using it too much. Because purple shampoo contains a specific ratio of blue and red pigments to correct unwanted brassiness in blonde hair. And when you try it too often for quicker results, the results can turn the other way around.

Also, some purple shampoo contains sulfate. Do you know what sulfates do to your hair? Let me tell you; that sulfates are a group of chemicals that act as a detergent and can suck all the moisture from your scalp and hair, making them dry, brittle, and prone to breakage. So, if you are already facing dryness issues, then purple shampoo is not for you, my friend.

Now the question arises, how often is too often? Well, it is different for everybody as the degree of brassiness also varies. For shoulder-length hairs, once a week should be enough, whereas, for longer hairs, you can use it bi-weekly.

What are the benefits of using purple shampoo?

Every bad thing has some good in it. So, let’s find out what’s good in the purple shampoo.

Brassiness neuralization: I am sure you already know this benefit of purple shampoo. But here, I will include it for the newbies. Suppose you have blonde hair, and after a few washes, it starts looking yellowish. In that case, purple shampoo take hold of that brassiness and turns your brassy hair into ashy blonde hair.

Hair texture improvement:  Yes, instead of disturbing the texture of your hair, purple shampoo gives a smooth surface to your hair.

Hair follicle strengthening: It’s been a myth that purple shampoo makes your hair roots weak. But it’s not true because the ingredients present in the purple shampoo are effective enough to make your hair roots strong.

Conclusion

I hope, by now, you must have understood that purple shampoo is not bad for your hair. But this statement comes with a big BUT. If you use it wisely and in moderation, then forget about the cons because there are more pros. But if you over-use it or don’t follow the rule of moderation, then a big NO from me.

Also, the usage frequency can differ depending on the degree of brassiness. So, if you have shoulder-length light blonde hair, then once a week should be enough. And bi-weekly if the length crosses the shoulder and brassiness is high.
