It was overseen by Dr Bessam Farjo at the Farjo Hair Institute in Manchester, which holds the UK's only Certification of Excellence for procedure.
Platt, who lives in Cheshire, said: "I've struggled with male pattern hair loss for many years, and eventually got to a point where I decided it was time to address it. I'd seen the results of other public figures' transplants and I thought, why not? Being on television meant that my hair - or lack of it - was very visible.
"I admit that I was more than a little nervous about having a robot perform surgery on me, but Dr Farjo and his team looked after me exceptionally well from start to finish and I'm really impressed with the final results. Having the robot working on my head was nowhere near as strange as I thought it would be once I had become used to it."
He said he researched the topic of hair transplantation for several months, approaching Dr Farjo following personal recommendations. He decided to have his robotic procedure after hearing about the benefits of the procedure.
The robot harvested donor hairs from the rear of his head before Dr Farjo and his team manually transplanted them to create his new hairline.
Platt started to grow new hairs after around three months and now, 18 months later, the full extent of new hair growth is apparent.
He said: "Although it took some time before the results were really noticeable, I'm thrilled with my new look and really impressed with my new hairline. I'm delighted I went through with it and feel much more comfortable under the lights of a television studio!"
That's his problem, right there: "The robot harvested donor hairs from the rear of his head before Dr Farjo and his team manually transplanted them to create his new hairline". It' obviously ran out of hairs on the rear of his head. He'll have to go back like Rooney did to have his pubes put up there, too.
