The secret to perfecting blue-grey hair is knowing that there’s no single colour technique to use. There are so many ways to try the trend, from a grey-to-blue ombre, to a root-to-tip fusion of the two hues. Paint them, melt them and blend them together through hair, any way your client wishes. But make sure you have these essential tips to guide you en route to the dreamiest hue…
1. Map Out the Technique
Speak to your client about the blue-grey look they hope to achieve, so you can plan the right formulas and choose the right technique accordingly. Some of the styles they could try include a blue-grey balayage, blue highlights on a charcoal base, or sweeps of silver and cobalt through platinum blonde hair.
2. Brighten with the Base
Unless you’re already working with a very light base, you’ll need to pre-lighten hair before you apply any blue or grey colours over the top. Doing so will create a clean, bright canvas for the tones to stand out. Try it with BlondorPlex; a pre-lightener infused with our hair-strengthening WellaPlex No1 Bond Maker.
3. Choose the Right Colour Products
There are vibrant blues and glistening greys across the Wella portfolio, meaning that finding the perfect shades to mix up won’t be difficult. However, it’s important you choose a colour product that suits your client’s needs and lifestyle. Decode their colour product with this speedy lowdown:
For rich, healthy-looking colour, opt for permanent Koleston Perfect, which boasts a raft of silvery greys, alongside a true blue Special Mix shade, 0/88.
For beautiful pastelization and bespoke tonal results, use semi-permanent Color Fresh and Color Fresh CREATE. The latter features a bright New Blue which you can personalize by mixing with deeper or softer pastel hues.
For vibrant, transformative results, enjoy playing with demi-permanent Color Touch. Like Koleston Perfect, it features a bright blue Special Mix shade that teams beautifully with cool greys.
