An 11-year-old Thai girl has been officially named the world's hairiest by the Guinness Book of Records.Supatra Sasuphan used to be teased and was often reduced to tears by being called the likes of 'wolf girl' and 'monkey face'.But now, the little girl, who has thick hair growing all over her face, ears, arms, legs, is delighted after her new found fame helped her become one of the most popular girls in school.Supatra, nicknamed Nat, is one of only 50 documented cases of Ambras Syndrome since the Middle Ages, reports The Sun.Before the disease was understood, sufferers were branded 'werewolves' but the condition is actually caused by a faulty chromosome.She has attempted to remove the hair in the past with lasers but the treatment proved unsuccessful and it just kept growing back.Supatra said: "There were a few people who used to tease me and call me monkey face but they don't do it any more."I'm very used to this condition. I can't feel the hair as it has always been like this. I don't feel anything."It does sometimes make it difficult to see when it gets long. I hope I will be cured one day."Source: ananova.com
