Who said blondes get to have all the fun? For years, blondes have used purple shampoo to cancel out brassy orange and yellowish tones. Now brunettes have a secret weapon all their own—blue shampoo!

But what is blue shampoo? And what does blue shampoo actually do? Well, just as the purple pigments in purple shampoo neutralize brassy tones in blonde hair, the blue pigments in blue shampoo cancel out the unwanted orange, red, and copper tones brunettes often battle—especially color-treated brunettes.

So if you love dressing up your brown locks with cool caramel highlights or a trendy balayage, listen up! Here’s everything you need to know about blue shampoo and how to use it.

 
What Does Blue Shampoo Do for Brassy Brunettes?

Like purple shampoo for blondes, blue shampoos are actually formulated to ditch brassiness in color-treated brunette hair. From deep chocolate to golden brown, all brunettes have underlying orange and red pigments that combine to form their hair color. When you lighten brunette hair, those underlying pigments can show through after weeks of sun exposure, heat styling, and shampooing.

Dust off that elementary school color wheel and you’ll see that while yellow and light orange shades are across from purple and violet, 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.

Washing several times a week with a blue shampoo and conditioner like our Blue Crush shampoo and conditioner helps keep your beautiful brown locks shiny, toned and fresh. Even natural brunettes can benefit from blue shampoo every once in a while. Blue shampoo can subtly alter warmer, coppery tones in your virgin brown locks to cooler, ashy shades.

 
How to Use Blue Shampoo

They say you can never have too much of a good thing, but that doesn’t necessarily apply to blue shampoo. Using too much blue shampoo too often can leave you with a darker shade than you desire. Here’s how to properly use blue shampoo to neutralize brassy tones and keep the cool brunette color you crave. 

 
1. Alternate Blue Shampoo with Your Regular Go-To

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.

Blue shampoo works by coating the hair shaft, neutralizing brassiness, and adding gorgeous shine. So while you want to concentrate on your scalp and roots when shampooing with your regular product, make sure to incorporate blue shampoo evenly throughout your hair to get the desired effect. Leave it on for two to three minutes before rinsing for a deeper tone.

 
2. Follow Up with a Blue Conditioner

Conditioner is especially important for dehydrated color-treated locks. Dying and highlighting your strands strips them of their natural moisture. Hydrate your strands with a deeply moisturizing conditioner after every shampoo.

Double up on the toning power by using a blue conditioner after each wash with blue shampoo. In just one use, you’ll see a brighter, fresher, cooler brown.

 
3. Seal In Your Color

Protect your color longer by using a nourishing hair serum. It’ll boost shine and seal your hair’s cuticle, locking in both moisture and those cool, perfectly-toned brown hues your blue shampoo and conditioner have left you with.
