It's possibly the least office-appropriate beauty trend ever, but the craze for Crayola-coloured hair, which created such a huge beauty buzz throughout the summer, shows little sign of abating.
Once the almost exclusive preserve of students, festival-goers and the characters of '80s TV show Jem and the Holograms, outré and unnatural shades have been rearing their heads in the mainstream of late.
Katy Perry debuted a lavender mop at the MTV Video Music Awards, and while it looked good it wasn't especially surprising: Ms Perry often dabbles in bright and bold hair colours, dramatically switches up her style as often as the rest of us change our knickers -- and isn't exactly known for showcasing understated looks. However, rainbow hues have recently been finding favour with a slew of unexpected celebs who are normally more inclined to play it safe with their hair and beauty choices. Among the unusual suspects are Glee star Dianna Agron and country singer Carrie Underwood, both of whom have chosen shocking pink to give their blonde locks a lift.
Kate Bosworth, meanwhile, dip-dyed the ends of her hair cool turquoise as part of her breakover when she split from True Blood's Alexander Skarsgard.
The fashion world has taken to hitting the bottle, too. Jeremy Scott and Richard Chai were just two of the designers who featured out-there hair colours in their autumn/winter 2011 shows. While models at Roksanda Ilincic, Thakoon and PPQ sashayed down the recent fashion-week runways with candy-coloured barnets.
So it's got more high-profile fans than you could shake a comb at and is fashion's latest darling 'do, but can alternative colour really work in the real world?
At Style Club, I'm told that it has now overtaken traditional colouring processes -- including highlights -- in popularity.
Since I've wanted to dye my hair pink for a long time, I was more than happy to hop aboard this particular beauty bandwagon in the interests of research, with the result that I'm currently sporting a pink dip-dye job.
Basically, the last couple of inches of my hair have been bleached of their natural light brown hue and hand-painted with pink dye, and I flipping love it.
It's the perfect way to dip into the trend, can easily be hidden in a bun for work, and trimmed out when it's time for a change.
Dip-dye colour and cut costs €150 at Style Club, where there's currently 20pc off all hairdressing services. 12 South William Street, Dublin 2. Call (01) 472 2444
