Now footballer Wayne Rooney is the latest, and youngest, celebrity to admit to undergoing a hair transplant. Fed up with teasing over his baldness, Rooney revealed on Twitter at the weekend that he has taken action. He tweeted: 'Just to confirm to all my followers I have had a hair transplant. I was going bald at 25 why not. I'm delighted with the result.' He later added: 'It's still a bit bruised and swollen when it dies down u will be first to see it. Anyone recommend any good hair gel. Haha. His wife, Coleen, tweeted: "Hiya!! Yes waynes had his hair done! His own decision not me asking him, like alot are saying!! Pleased for him and it will look great x'. Rooney's team-mate, Rio Ferdinand, posted: 'just don't go down the wearing a alice band route!! You'll be doing head&shoulders adverts soon! Hope its gone ok Good luck lad'. The clinic uses follicular transfer, whereby hairs are transplanted in groups of 1-4 and grow naturally in the scalp. It claims the method is 'undetectable' and a 'major advance over older hair transplantation procedures that used larger grafts' and often produced an 'unnatural look'. The technique is a two-step procedure, the clinic says on its website. The procedure is 'minimally invasive' and, therefore offers a reduced recovery time and reduced risk of complications. That's hardly surprising: a hair transplant is a brutal, as well as an expensive, process, with the full works costing as much at £32,000 (admittedly not a problem for someone paid £150,000 a week to kick a ball). Dr Maurice Collins, the surgeon who performed Irish actor James Nesbitt's two highly publicised operations, charges £7.60 for each hair follicle he transplants at the Hair Restoration Blackrock clinic, outside Dublin. Given that a patient is likely to need anything from 1,000 to 4,500 follicles transplanted, the procedure would cost a bare minimum of £7,000. There is typically a team of 18 people working on a transplant, which can take eight hours. The technicians, nurses and surgeon need to ensure the hair is kept alive when it is deprived of oxygen outside the body. The key is getting it back into the patient's head as soon as possible.
