If the brunette tones in your hair are looking dull, these blue shampoos will help

Brunette and haven't heard of using blue shampoo before? Me neither, until I found out it's about time we brunette ladies took note. Using the best blue shampoo can help you get the most out of your dyed or natural colour when washing. (Did you know there's a way to properly wash your hair?!) Yes, really. Although definitely the lesser well known of the two, blue shampoo is to brunette hair what the best purple shampoo is to cool-girl blonde.

Most people associate brassiness or unwanted warm tones with bottle blondes. But the truth is that brunettes may experience some unwanted orange or reddish hues when a cool brown is preferable. Intrigued? Keep scrolling for everything you need to know on how blue shampoo works, and the best blue shampoo on the market right now. 

Why do brunettes need blue shampoo?

Left the salon with a fresh gloss, feeling fabulous, for the copper you were trying to shake start coming through after a few weeks? A good blue shampoo may be the hair saviour you're looking for. 

"Although it appears not to be as widely known, brunettes also find that they are left with unwanted brassy tones coming through if they lighten their hair and/or have balayage," says legendary hairdresser and colourist Josh Wood. 

Thought it was only bleach blondes that had this issue? Think again. "This can happen as a result of the sun, product they may use and pollution. Meanwhile brunettes with virgin hair will often find that they have unwanted warmer tones too."

Brunette hair has more melanin than blonde strands, when it's lightened (in the salon or by the sun) the pigment is removed, resulting in a warmer or copper tone. Which may be perfect for the summer months but if copper isn't what you are going for, then a blue shampoo may be your answer. 

Of course, a toner can help with this, but pigments from the toner fade over time too which can leave your locks with a brassy undertone. That's where blue shampoo comes in...

What is blue shampoo?

The term blue shampoo is pretty self-explanatory—the shampoo formula is enriched with blue pigments that infuse into the hair. Won't that turn my hair blue, we hear you ask? Not quite, as the process is a little bit more scientific than that.

How does blue shampoo for brown hair work?

If you think about the colour wheel, blue is opposite orange and therefore has the ability to 'cool down' these tones in your hair. The blue works to counteract the orange or coppery tones.

 "Blue shampoo is a neutralising shampoo that will reduce and neutralise orange and brassy tones in the hair," Josh explains. "Redken Brownlights Shampoo is a great way to tone your hair; the blue pigments work quickly and give incredible, cool results."

How to use blue shampoo?

Leave your formula on the hair for a few minutes to really get the most out of those blue pigments, and most formulas advise using gloves so as not to stain your hands blue.

Emilie Venturini, Artistic Colourist at Gielly Green shares her expert advice on how to get the most out of your new blue shampoo. "I would say use blue shampoo no more than once a week focusing on the scalp but ensuring you are working through the ends to evenly distribute the tone." She explains. "You should see results from the first use however the blue tone does build up in the hair shaft so the more you use it the less orange/ red tones you will see in the hair."
