Harry Styles, former One Direction star posted a photo showing cut-off ponytail earlier this month. He said that the hair would go to a charity that provides wigs for young cancer patients.
He looked with a clean-cut look on the sets of Christopher Nolan's World War II film 'Dunkirk'.
The film is based on the real life Dunkirk evacuation from the French coast, which was one of the biggest operations of the Second World War.
