Denim has become the go-to hair color for fashionistas, according to Cosmopolitan magazine. The cutting edge shade has become a popular feature on social media, with several users posting images of their denim dos.

Much like the eponymous fabric, denim hair spans several shades of blue, from stonewash to navy, and the key to recreating the look is to avoid block colour, by combining several shades together for a multi-tonal finish.  

L’Oréal Professional is hot on the heels of this latest trend, with backstage Hair Stylist Adam Reed of Percy and Reed recreating the look using the brand’s Professional Color Technology.
