A bit of a mea culpa may be in order here. We reported (hoped?) that unnaturally-colored dip dye was a trend that was going to be left back in 2011. The spring 2012 runways (which we saw back in February of this year) proved that colored hair had moved, as these things sometimes do, from the street to the runway. The result? The trend for neon and pastel hair, especially pink, is hanging on and we’d even argue is gaining momentum.

The famously pink-haired model Charlotte Free just landed a contract with Maybelline, which is a pretty mainstream gig for neon hair. Even Joan Rivers went pink for a bit (see above). And Lauren Conrad is a serial pink dyer–she can’t lay off the neon. She dip-dyed her ponytail fuchsia a few weeks ago, and let’s not forget the internet frenzy she caused when she did pink, blue and lavender streaks last year. Coco Rocha made her waves Schiaparelli shocking pink for the Met Gala. So it’s a thing, and that’s ok.

Want to partake? We talked to a gaggle of experts to get their advice for how to get bright hair, how to keep it, and how to get rid of it (we know from experience that having pink hair gets tiresome. And hard to coordinate with outfits.) At the end we’ve given you a lovely gallery of bright-hued ladies to give you some inspiration.
