Bald teen overcomes hair-pulling disorder to win beauty pageant

Undated photo shows Sarah Pennington. Sarah developed trichotillomania at the age of 11, which causes her to pluck out her strawberry blonde locks, eyebrows and eyelashes. Her irresistible urge to pull left her hiding the short patch remnants of hair beneath bandanas, hats and wigs, before receiving psychiatric help three years ago. She learnt to embrace her baldness and stop covering herself in public, eventually going onto speak out in public about the mental health disorder. [Photo: IC]
