Katy Perry has taken to experimenting with her hair colour, wearing a selection of wigs in bright hues and, most recently, sporting streaks of vivid colour flashing through her hair (pictured).
Rihanna, meanwhile, just seems to like red, a bright synthetic shade she’s been wearing for months now.
So we’re starting to wonder if this could be a new trend that’s going to follow through to the high street. Especially when news came through that Paul Mitchell haircare has launched a range of daring shades that are the opposite of natural looking.
There are royal blues, baby pinks, purples, oranges, reds and even grey – which has already been seen on celebrities from model Kristen McMenemy to singer Ellie Goulding.
The colour is temporary – although more so on natural hair; pre-lightened hair, which is more porous, will 'grab' the colour more intensely for a longer lasting result.
So you can add just slices through your normal hair colour or have it stroked through underlying sections to give a glimpse of a more adventurous side.
The Inkworks range is available through Paul Mitchell salons; call 0845 659 0012 or visit www.paul-mitchell.co.uk for your nearest.
