How to Banish Brassy Hair In and Out of the Salon

The first step to fixing brassy hair in the salon is checking the Wella Colour Wheel; a hair colour chart that follows the rules of colour theory to show you which shades neutralize unwanted tones. In the case of brassiness, the tones are typically orange or yellow, so you must consult the wheel to see which colours sit opposite. These will cancel out excess warmth.

So, if you want to know how to get rid of yellow hair, hints of /6 Violet (Cool) should be added to your formula. For orangey locks, /8 Pearl (Blue) will cool down strands and create a refreshed finish. You may even find reddish undertones in hair that’s faded brassy, meaning you’ll need to mix in a dose of /2 Matt (Green). Think of it like colour therapy for locks.

But what do these numbers actually mean? They form part of Wella’s Shade Numbering System, which features up to four key components: 1) tonal intensity, 2) depth of colour, then after the slash, 3) major tone of colour and 4) minor tone of colour. Your neutralizing hue is usually the major tone, or the minor tone. For example, the major tone for 4/71 is /7 Brown, making this colour’s full shade name Medium Brown Ash. Meanwhile, one of our most popular blonde toners, 9/16, would be a Very Light Blonde Ash Violet.

1. Use a Hair Toner for Brassiness

For clients who want their colour touched up or their freshly-lightened locks beautifully balanced, a toner is your go-to. Try mixing in a shade with a major or minor tone of colour that’s /2, /6 or /8. Choose the product based on their desired final look and level of commitment; Color Fresh for a semi-permanent boost, Color Touch for a demi-permanent refresh, Koleston Perfect for pure, even results, and Illumina Color for a sheer, permanent color results with natural luminosity.

While you’ve got all the tips, tricks and techniques you need to fix brassy hair in the salon, you can help your client maintain their shade for longer by passing on key advice.

If they’re prone to brassiness, these are the at-home rituals to recommend…

1. Introduce a Purple Shampoo

Contrary to popular belief, purple shampoo isn’t just for cool-toned blondes. The violet-tinted formula can actually banish excess warmth in any hair colour. Use it to balance a brunette balayage, keep copper hair in check or brighten grey hair. We love INVIGO Cool Blonde Color Refreshing Shampoo, which should be left in for three to five minutes to maintain vibrancy.

2. Alternate with a Colour-Kind Shampoo

Clients don’t have to use their purple shampoo for every wash. They could alternate with a colour-kind formula, like ColorMotion+ Color Protection Shampoo. Infused with antioxidants that forage and capture damaging free radicals, it also bumps up shine to make their locks look smoother and silkier wash after wash.

3. Suggest a Colour-Depositing Mask

For clients who crave the moisture of a mask and the look of freshly-coloured hair, recommend the new Color Fresh Mask. This weekly treatment plies parched strands with rich, nourishing oils, while depositing a tint that corrects brassy tones. The Pearl Blonde edition is perfect for brightening icy and platinum hair shades, while Lilac Frost will diminish excess warmth on any hair colour.

4. Tell Clients How to Swim Smart

If they hit the pool regularly, swim caps are a must. Chlorine can make your client’s dream shade shift, while stripping strands of natural oils to leave hair dry and brittle. Those who don’t have a cap should use the INVIGO Color Brilliance, ColorMotion+ or Elements Renewing Shampoo, as they each contain Wella’s EDDS technology, which can protect against chlorinated water.
