Calum Best is rumoured to be heading back to the Celebrity Big Brother house.
January's show features a combination of new celebrity housemates and much-loved stars who have been popular in previous CBB series.
Calum, 35, reckons the three procedures have made him look at least five years younger and helped to prolong his TV and modelling career.
For a celebrity like Calum, his looks are everything. As well as CBB and numerous other TV appearances, he has also had his own after shave and supplement ranges.
Would these opportunities have come his way if he had not worked so hard with Crown Clinic to keep a full head of hair?
Here's a run-down on Calum's three procedures - all through the FUE (follicular unit extraction) method which has been used by several other celebrity patients at Crown Clinic including football pundit Didi Hamann, Gogglebox star Chris Steed and Martin Roberts, who recently starred on I'm A Celeb. Other Crown Clinic celebrity patients such as TV doctor Christian Jessen have used the more traditional follicular unit transplantation (FUT) method.
Hair transplant 1
Calum had 1,200 grafts (amounting to 1,850 individual hairs) moved from the side of his scalp to the front after a 'Croydon facelift' caused him to go bald in his early 20s.
He had adopted the scraped back pony-tail hair style made famous by Croydon model Kate Moss - and it damaged his hair and scalp.
He said his hair loss had made him insecure at auditions.
"You drop your head to look at your phone and you are thinking all the time, 'Are they looking at my bald spot?,'" he explained.
Hair transplant 2
Calum had 1,257 grafts (amounting to 2,228 individual hairs) moved from the side of his scalp to the front a year after his first procedure.
The star could have possibly avoided the need for a second procedure if he had taken the clinically proven drug Propecia, also known as Finasteride. This would not have grown him any new hair but it would have slowed down or halted the loss of his natural hair.
All of Calum's transplanted hair is permanent and should last him for the rest of his life. The problem he has is hair loss is a continual process and if he will not take Propecia, then his natural hair loss will continue.
Calum said: "I had the second procedure because I was so pleased with the first one and how it helped to boost my confidence and work opportunities."
Hair transplant 3
A year later, Calum had his third procedure at Crown Clinic. He had 1,200 grafts move to the front his scalp to prepare for his appearance on Celebrity Big Brother.
Calum said: "There is no doubt the three procedures have changed my life. I have been losing my hair since my early 20s. Nature's plan was for me to have thin and patchy hair across the top of my scalp.
"But the great thing is, we don't have to follow nature's plan.
"Hair transplant technology has improved so much in the last five years and I have been able to keep hold of all my hair and wear it in the same way I did when I was in my teens.
"I was keen to get it done before going on Celebrity Big Brother so my hair would look great on the show."
