Mick Jagger's hair sells for $6,000 at auction An envelope containing a lock of Mick Jagger's "washed and trimmed" hair has fetched a sizable sum this week at auction. An anonymous buyer paid 4,000 pounds -- or about $6,000 -- for the clump of the Rolling Stones frontman's hair. According to Reuters, that is double the price the singer's strands were expected to sell for. Rolling Stones artifacts on display The hair, put up for auction by Jagger's former girlfriend Chrissie Shrimpton, was placed in a small envelope with the message, "Mick Jagger's hair after being washed + trimmed by Chris at Rose Hill Farm." Shrimpton met Jagger when he was a student at the London School of Economics. The item was offered for sale to raise money for the charity Changing Faces, a U.K.-based organization that works with people who have suffered disfigurements. Other items offered for sale at the auction Wednesday included a guitar owned by Led Zeppelin's Jimmy Page and a set of handwritten lyrics by David Bowie for his song "The Jean Genie." Jagger, who turns 70 on July 26, will perform with the Rolling Stones in London's Hyde Park this weekend as part of the British Summer Time festival.
