On average we lose between 50 and 100 hairs a day that will naturally be replaced by new growth but as we age, this growth rate slows.
Male baldness, which is hereditary, usually occurs in middle-aged men but can also happen earlier.

At the height of his career, Elton John was a wild child but also a little thin on top. After extensive hair treatment he transformed his hairline, regaining a full head of hair. Elton's transplant is an effective example of how well hair plugs can work. Considering experts believe the earlier the procedure is done the more likely the hair will revert, Elton has defied the odds.
After appearing at a charity gala event last year with more hair than normal, there was plenty of speculation that James Nesbitt had undergone another transplant to gain a fuller head of hair. The 45-year-old actor had previously tackled his hair loss problem in 2009 and admitted to having had more work done in late 2010.
In a video testimonial for the Hair Restoration Blackrock (HRBR) clinic James spoke openly about his hair loss struggle, "I'm an actor so I'm in the public eye a lot and I really felt that my hair loss could affect my career prospects."

It has been reported that Gordon Ramsay spent close to £30,000 on his hair transplant though you'd be hard pressed to see any discernable difference. The celebrity chef was papped leaving an LA clinic in December 2010 with a black surgical band over this head, which could suggest he had added to his thinning hairline.
Dr Antonio Armani, a hair transplant guru is believed to have performed the radical treatment, called 'follicular unit extraction' that requires no stitches and leaves no scars.
Back in 2007 Ducan Bannatyne appeared on an ITV1 show 'Fortune Million Pound Giveaway' where ordinary people ask a panel of millionaires for money, for a reasons special to them. A young man happened to ask for money for a hair transplant and Duncan advised the guy that "Dr Farjo is the best; no one will ever know you had it done!" Well, they will now that you announced it. Duncan! The entrepreneur had his treatment done a year earlier in 2006, so he would know.
Ex-Eastenders actor Shaun Williamson, known for his role as Barry Evans was also a patient at the Farjo clinic. He made a documentary, 'Wish You Were Hair' about his treatment that appeared on Sky TV's Discovery Home & Health channel in 2005. The actor's hair had started receding at an early age and by the time he had left Eastenders he was completely bald.
Shaun then moved into acting in pantomimes and after talking with his agents, he felt that a change of image was required.
Dancing On Ice judge Jason Gardiner stole the show at the 2011 finale when he revealed his new hairline. The 39-year-old was so impressed with contestant Laura Hamliton's 10/10 performance that he took his hat off to compliment her. At the same time the audience was shocked to see a new tuff of hair on the acid tongue judge who was entirely bald at the beginning of the year.
