Hair bleaching is the kind of thing private school boys do during the summer holidays because their principal won't allow blondie locks throughout the school year. You see them around, hanging outside McDonalds checking out the effects of Sun-In on each other's scalps, pretending to be hot frat boy lifeguard types, when really, they're just rich sheep. Rich, yellow-headed, sheep.

Brad Pitt does it now and then when he and his bird have a tiff, while Colin Farrell has also been partial to dumping a load of Clorox over his head when he feels the need to act cool. A couple of weeks ago, Pete Doherty appeared white headed in a covert shot taken by a 'friend' of his making a crack pipe. He was back to the brown, ahem, a day later.

Mark Vaughan, the Dublin supremo is having a bit of a white head moment. Maybe he's follicley reminiscing on his days at Blackrock College when a bit of blonde on the head was all the rage. But we all know the real reasons for bleaching, it's a dissatisfaction with one's hair colour (usually ginger people, sorry) dressed up as radicalism. Either that, or hair-tention deficit disorder as suffered by David Beckham, the master of variations on blonde dye.

From footballers who mass-bleach in gangs to attention-seeking actors, bleaching does nothing but paint the perpetrator as a wannabe rebel, or someone insecure with their real do.

Keep it natural boys. Or if you're really that unhappy, just shave it off.
