What Is Blue Shampoo?

We’ve all heard of purple shampoo for blondes, now brunettes have a go-to toning product too! Let’s be real, brass can be a buzzkill when you’re aiming for cooler and lighter tones. So, we worked with our expert Devachan Colorists to develop a special shampoo to tone and cleanse all at the same time. Meet No-Poo Blue®!

Why use blue shampoo?

Like we said, brass is a pain in the…neck. So, what does blue shampoo do? Blue-tinted shampoo tames brassy tones in brunette hair. If you have highlights, balayage, ombré, or lightened hair completely, blue shampoo can lengthen the life of your hue and keep it fresh between appointments. Plus, if you’re aiming for a deep, shiny brown look, or if you're someone who spends a lot of time in the sun, you also might want to give it a try!

Purple vs Blue Shampoo

At this point you may still be asking: “Why should I use blue shampoo instead of purple shampoo, don’t they do the same thing?" To answer this question, we must go back to art class and look at the color wheel. To neutralize brassy tones in hair we have to look to the opposite side of the color wheel to see what color needs to be deposited into the hair to neutralize the color.

For example, in blonde hair, brassy tones manifest as yellow. And what color is across from yellow on the color wheel? If you said purple, you’d be right!

As for brunettes, brown hair can be a mix of various colors and your shade of brown is determined by the primary pigments in your hair. For instance, if you have a deeper, more espresso-toned shade, you've got more red pigmentation. Mid-shades of brown have a red-orange pigmentation, and the lightest browns have orange pigments.

Therefore, when it comes to brunette hair, brassy tones show up as a more orange-red and blue is the neutralizing color for these hues. So, blue shampoo is more suited for brunettes! And although blue shampoo is most often recommended for color-treated brown hair, natural brunettes could benefit too especially if their hair picks up natural pigment from the sun.

In all, it’s a good idea to balance tones with a blue shampoo!


How do you use blue shampoo?

Before a full head application, we recommend doing a strand test. Section out a 1x1 inch section of hair at the nape of your neck, wet the section and apply No-Poo Blue® to the section. Leave on for 1-3 minutes and rinse. Dry the section to ensure results are as desired. Once you have tested it, feel free to apply it to your whole head.

Our colorists also recommend using No-Poo Blue® every 2-3 washes and alternating with your regular shampoo.

For more toning power, leave on for 2-3 minutes before rinsing. Keep in mind, if you use No-Poo Blue® too frequently you could over-tone the hair.
