I. What is Blue Shampoo?


 Blue shampoo is a specialized hair care product designed to address the needs of individuals with brunette or dark-colored hair, particularly those who struggle with unwanted brassy or orange undertones in their hair. These blue pigments help to neutralize warm and/or brassy tones in the hair, restoring the hair’s cooler, ashy, or natural brown undertones.

II. How Does It Work?

 Like purple shampoo for blondes, blue shampoos are formulated to ditch brassiness in color-treated brunette hair. All brunettes have underlying orange and red pigments that combine to form their hair color, from deep chocolate to golden brown. Brassy tones in brunette hair often occur when the hair’s natural color pigments (melanin) are exposed to elements like sunlight, hard water, or even some hair care products. Over time, these environmental factors can cause the hair to develop warm, reddish, or orange undertones, diminishing the richness and depth of the natural brown or brunette shade.

 The blue shampoo is formulated with blue pigments that work on the principles of color theory, where colors on the opposite sides of the color wheel cancel each other out. Dust off that elementary school color wheel, and you’ll see that darker orange and red shades are opposite blue. That’s why the blue pigment in blue shampoo works to cancel out dull, brassy tones in brunette hair. Instead of turning your hair blue, these pigments temporarily deposited onto the hair shaft, resulting in a cooler-toned effect when applied to brunette hair. It removes brassy tones so your beautiful brunette shines through.

III. How is Purple Shampoo Different From Blue Shampoo?

 Blue shampoos and purple shampoos—while similar—are not interchangeable. The difference between them can be understood by looking at the color wheel. The key difference is that blue shampoo neutralizes orange tones in the hair (which is common for brunettes) and purple shampoo neutralizes yellow tones in the hair (which is common for blondes).


 Purple and violet can be found opposite of yellow and light orange. These yellow and light orange hues are often found in blonde hair, so purple shampoo eliminates those brassy tones. While blue is the opposite of darker orange and red on the color wheel, which is the brassy tone often found in brunette hair. As a result, it is the best fit for getting rid of brassiness in darker hair. If blue shampoo is used on blonde hair, you run the risk of ending up with a weird greenish hue. On the flip side, if you use purple shampoo on brunette hair, it won’t be strong enough to cancel out the orange, she points out.

IV. How To Use Blue Shampoo?

 Blue shampoo works by coating the hair shaft, neutralizing brassiness, and adding gorgeous shine. Here’s how to properly use this shampoo to neutralize brassy tones and keep the cool brunette color you crave:

  • Step #1: Gently massage blue shampoo into your wet hair. Make sure to incorporate evenly throughout your hair to get the desired effect.
  • Step #2: Lather and leave it to absorb for 3 to 7 minutes.
  • Step #3: Rinse. Use the blue shampoo daily until the brassiness disappears. Then, alternate with your regular shampoo to maintain the results.

→ The blue pigment in blue shampoo can be a powerful surface toner. Shampooing once or twice a week with blue shampoo should be enough to keep any orange or red tones from showing through. If you need to wash in the meantime, use a nourishing, color-safe shampoo like our anti-frizz shampoo to keep your locks soft and healthy-looking.
