Movie goers saw his hair altered into a comical perm style for the critically acclaimed film American Hustle, but in real life Bradley Cooper’s hair is no laughing matter, with reports that the handsome actor has been taking hair loss medication Propecia (Finasteride) in a bid to avert his familial trait of baldness. The 39-year-old actor came to prominence in TV show Alias before featuring in a supporting role in the 2005 Wedding Crashers. However, in the subsequent 9 years his career has skyrocketed and Cooper has had leading roles in numerous successful films such as The Hangover series, Limitless (2011) and Silver Linings Playbook (2012), for which he was nominated for an Academy Award. Cooper, dating 21-year-old model Suki Waterhouse, clearly wants to retain his leading man status and is worried about a receding hairline. According to a source who spoke to US website RadarOnline, the actor “is so anxious about his receding hairline that he’s turned to [balding remedy] Propecia. He has a lot of bald guys in his family, so he’s been on Propecia for a couple of years. And to his delight, it seems to be working.” During filming of last years The Hangover 3, Cooper and the other two male leads, Zack Galifianakis and Ed Helms apparently “had their own dedicated hairstylists, a first for the franchise and something that was demanded by Bradley” due to his hair loss concerns. The source added: “Bradley is determined not to go bald and lose his leading man looks.” Hair loss medication Propecia has made news in recent years on a few occasions after Manchester  United striker Wayne Rooney was rumoured to be taking it to prevent further hair loss and Canadian popstar Justin Bieber even commenting on Prince William's diminishing mane, saying the Prince should be taking Propecia. Rooney and other celebrities such as Calum Best and James Nesbitt have since opted for incredibly expensive hair transplants, but there has inexplicably been a mass silence in regards to any admittance to celebrities taking Propecia. Spencer Stevenson, the hair loss expert who fronts the specialist talk show The Bald Truth, advises balding men to consider taking Propecia prior to any costly hair transplant procedure. He says: “Before you even consider a hair transplant, look into going on Propecia or applying Minoxidil (a topical hair-loss treatment contained in Regaine Foam) for at least six months first, to strengthen existing hair and prevent further hair loss.”
