A young Thai girl with a rare genetic condition that causes her to have thick hair over most of her body has set a new Guinness World Record as the hairiest child.Supatra “Nat” Sasuphan was born with hypertrichosis, which causes excessive hairiness and is sometimes referred to as “werewolf syndrome.” The 11-year-old girl’s father contacted Guinness World Record staff, requesting that they consider her for the title of hairiest child.Guinness World Record judges evaluated Sasuphan’s body hair using the Ferriman Gallwey method, which consists of measuring the amount of hair on nine different parts of the body – the upper lip, chin, chest, back, abdomen, arm, forearm, thigh, and lower leg.After assessing Sasuphan, the judges crowned her with the world’s hairiest child title on the GWR’s Italian TV show, “Lo Show dei Record.”
