Why Is Purple Shampoo Necessary For Blonde Hair?

Today I would like to share everything you need to know about brassy hair and purple shampoo for blonde hair.

After I’ve colored my hair blonde, I love the bright vibrant color. The tone is so rich and cool. But weeks after coloring my hair, I always start to notice that the shade of my hair is getting different. It has taken on an undesired yellow or orange tone. What is it? Brassy hair, that’s what. 

Brassiness refers to the unwanted warm tones that show up in colored hair. It typically happens in dark hair that gets dyed platinum or blonde, but it can also occur in hair that’s been highlighted or in hair that’s been lightened to brown.

Fortunately, we have several options when it comes dealing with brassy hair, in terms of both preventing it and fixing it after it happens. 

The best option for me is to wash my hair with purple shampoo to neutralize unwanted warm tones.

That’s why I tried a purple shampoo like Redken's Color Extend Blondage. Purple shampoo is just that shampoo with purple pigments that helps to keep undertones at bay. The concept of purple shampoo might sound a little crazy to the blonde newbies, but ask any tried and true blonde and they’ll tell you it’s a must-have for keeping hair looking strong and bright.

Why Is Purple Shampoo Necessary For Blonde Hair?

If you think of a color wheel, as basic as it sounds, whatever color you want to cancel out is directly across from it. So directly across from yellow is purple. That’s why purple helps eliminate the unwanted yellow colors from the hair. It’s almost like a way to brighten the color to a cooler tone. So, if the hair has a little bit of a yellow tone, a pigmented purple shampoo is going to neutralize that warmth.

These yellow or orange undertones can also be caused by things like sun, hard water or heat styling. For this reason, purple shampoo is not just for color-treated blondes. Natural blondes need it, too,

But keep in mind that purple shampoo does not replace your regular shampoo and should only be used once or twice a week. Because when you eliminate too much yellow, it visually ends up darker and a lot of people don’t want it to look darker. But I have a little tip, I always mix my purple shampoo with my regular shampoo to add some of the violet pigment into a regular hair cleansing routine without any risk of going overboard. 

I’m actually pretty happy with the Redken’s Color Extend Blondage products. Both shampoo and conditioner are formulated with a Triple Acid Protein complex, and wheat protein, that neutralizes unwanted undertones and helps strengthen hair’s cuticles while battling brass and keeping blondes bright. 

Do you already use purple shampoo? If so, which product do you use and are you satisfied with that product? Please let me know about your purple shampoo experience.

Take care,
