Purple Shampoo For Blonde Hair – To Eliminate The Unwanted Yellow Tones!

What is the challenging part of dying your hair? It certainly is maintaining the glossiness until your next trip to the salon. Unfortunately, no matter how much you try to take care of it, it will lose its shine with time. Whether you are a natural blonde or have dyed your hair a lighter color, you will start to notice signs of brassiness overtime. The only solution for this recurring problem is a purple shampoo. It can help you restore the vibrant and glossy color to your hair or even better, prevent brassiness from happening in the first place.

Purple shampoo for blonde hair

The color purple might come off as a surprise for a new user as it does sound bizarre. But purple shampoo is for those with light hair such as blonde, platinum, silver or gray, white, or pastel. It is an absolute necessity for bleached hair to use in between those hectic hair coloring sessions to keep the color bright and shiny without losing its gleam. 

What Is Purple Shampoo?

As these are specifically made for light-colored hair, you might question ‘why purple though?’. Similar to how you color correct while using makeup to minimize any imperfections, the color purple can correct the unwanted color yellow. This color theory goes way back to that color wheel you had to see every day from your elementary art class. How can purple shampoo correct or fight brassiness? In a nutshell, whatever color you want to cancel out is direct across from it in the color wheel. Those colors, known as complementary colors, can apparently neutralize each other and lessen the appearance of whatever color you want to minimize. As it turns out, purple falls directly opposite of color yellow in the color wheel. 

purple shampoo for brassy hair

In order to eliminate the unwanted yellow tones from blonde hair, the purple shampoo works perfectly to counteract and neutralize the warmth of brassy tones and restore its former brighter color.

The purple shampoo cleanses your blonde strands by dispensing sheer purple pigment that neutralizes to help you return your brassy color to a lighter tone. It will keep undertones at bay. However, purple shampoo should only be used once or twice a week as it does not replace your regular shampoo.

You cannot use it too much either because there is such a thing as too much purple. Purple shampoo can be a toner as any product that deposits pigment to correct hair color is considered as a toner. However, when you neutralize too much yellow by using too much purple, your hair will end up darker. To get better results, use the purple shampoo once a week if you normally wash your hair twice a week. 

How often should I use purple shampoo?

How often you should use it comes down to your choice. 

  • If you are a person who washes your hair twice or thrice a week, use the purple shampoo once a week. 
  • You have to be cautious of using some purple shampoos as they may stain if applied for too long and leave a blue-purple tinted hue on icy blonde hair. 
  • Use it as little as once a month or as much as twice a week, but like mentioned before, using too much may leave a purple tinge. 
  • Also, you can add the purple shampoo to your regular shampoo without going overboard. 
  • Regular usage of this vivid-colored shampoo will make a big difference in helping your hair keep the brass at bay while refreshing your hair color.

how to use purple shampoo

How long should you leave the purple shampoo in your hair? For better results, which is to fully penetrate the hair, you have to allow the violet shampoo to sit for three to five minutes before rinsing. Generally, the cooler the blonde, the longer you should let your blonde shampoo sit on your hair. To be more specific, if you are a warm blonde, let it sit for one to three minutes before rinsing and if you are a neutral blonde, wait for three to five minutes(1). On the other hand, if you are a cool blonde, you need to wait for at least five to fifteen minutes before rinsing.

Why is your blonde hair turning yellow?

Before going through the best purple shampoo for blonde hair, let’s see what could be the reason for your hair turning brassy. There are four possible reasons for this particular problem blondes face.

Underlying Pigment

It is possible for your hair to lose melanin — pigment — and turn light with a residual tone of the yellow left in the hair. This underlying pigment could leave your hair dull and pale. If you have bleached your hair to a lighter color, your natural color is lifted to make room for the new color.

But sadly your natural hair has some measure of underlying warmth that is often mitigated with a gloss at the salon. Eventually, this toner will wear off, giving brassiness a chance to come out. This is most likely because you are overdue for another color treatment. So in the meantime, you can use purple shampoo in your cleansing routine until you are off to the salon. 


Yes, your environment can damage your hair, as our environment is nowhere near healthy now. Also, because blonde hair is incredibly porous. It soaks up everything your hair is exposed to; from the harmful UV rays to the minerals or impurities in the water you shower in. Polluted air, smoke, chlorine from swimming, can sabotage your blonde strands to a point of wearing off the shine(2).

Moreover, they can weaken your hair shaft and cause breakage and damage. So, protect your hair from UV rays with a hat and by using a UV-protectant spray and use a swim cap while swimming in chlorine-filled water. If you can, install a water-filtering shower to not let the brassiness crawl back into your hair, thanks to the impurities such as traces of copper in the hardened water! 

Styling Products and Tools

Your hair can soak up whatever hair styling product you are using, too. Hair sprays, waxes, shampoos, and conditioners can all dispense a yellowish tint on the hair. When you are using too much heat from your styling tools, you are further damaging your hair by creating a yellowish tone. Before using purple shampoo on this already damaged hair, use a clarifying shampoo to balance the yellow pigment first. Plus, always, always use a heat protectant spray when styling and use good hot tools to style your hair. 


What you intake can affect everything inside you. Likewise, your diet and health condition will affect your hair. Oils from your scalp and medication can contribute to the yellow tinge in your blonde hair. 

Keep in mind all these reasons and take care of your blonde strands before the brassiness tears your hair. Another tough pill to swallow while taking care of your hair is to rinse your hair with cool water rather than warm water. To keep the glossiness and shine, close the cuticles and lock in moisture by rinsing with cool water.
