Sara Cox, Russell Kane, George Shelley and Kate Thornton are among celebrities supporting Great Ormond Street Hospital's #BadHairDay campaign, by sharing their bad hair photos.

The charity is encouraging the public to take part and donate £3, with money raised going to children across the UK who are suffering from the rarest and often life threatening conditions, by helping to fund pioneering new research, state of the art equipment and the hospital's redevelopment.
