When Kim Kardashian West unveiled her dramatic new do at Paris Fashion Week last month, brunettes the world over wondered: just how did she get her dark locks so light?
And with Lily Allen and Carol Vorderman recently taking the peroxide plunge too, salons have seen a spike in calls from would-be blondes.
But despite regular root touch-ups (all captured on Instagram, of course), Kim reverted back to her usual ebony shade within three weeks.
Most hair colour specialists will advise not to try a drastic change at home.
