Three identical twin brothers from Pembrokeshire, who once graced the screen on Cilla Black's Blind Date, are poised to undergo the world's first triplet hair transplant in Cardiff . Julian, Eliot, and Ryan Gregory, all 40, are scheduled to visit the same clinic today, Tuesday, May 13, for an identical procedure. This decision comes as the brothers have all experienced similar rates of hair loss due to their shared genetics and are now set to undergo a procedure at HQ Hair Transplants in Cardiff, where follicular units will be removed individually using a precise motorised punch. The clinic says "great care is taken with the grafts" before they are prepared for implantation into the triplets. Born in Haverfordwest, Pembrokeshire , brothers Julian, Eliot, and Ryan embarked on careers in modelling and acting. Never miss a Cardiff story by signing up to our daily newsletter here. However, they've said they've felt "less identical" as they've aged, primarily due to their receding hairlines which began in their thirties. Julian, now living in London, said: "We grew up being identical and the older we have got we feel the less identical we are getting. "So if we can have more similar hairlines again it would be nice to see the reaction of other people and feel more identical again." Having grown up playing pranks and swapping identities, the three men are now set to undergo their transplants together. Ryan, who also lives in London, said: "I think our hopes for the procedure is if we could roll back the years a bit. We have been together since we were in the womb and we always compare bits to each other like who has the most hair, who has got the biggest muscles and all the rest of it. "We have always been quite competitive so I think if we can realign the playing field a little bit and realign the hairline." Ryan admitted he started the search for the procedure when he started feeling insecure about his thinning hair. He said: "I have been wanting a hair transplant for probably ten years. I always said to people if there was anything I would pay for that was going to be cosmetic it would be a hair transplant. It has always been my most insecure bit of my body." The twins, who appeared on Cilla Black's Blind Date at the tender age of 18 and later featured in GQ magazine and Esquire, succeeded in persuading Elliot to join them for the procedure. Elliot, now based in Valencia, said: "Since my brothers have mentioned about the hair situation I have been looking at it a bit more and thought ok maybe I am ready to get the hair transplant done. I am looking forward to getting a fuller hairline." The clinic HQ Hair Transplants is operated and owned by ex-New Zealand All Blacks and Cardiff Blues rugby ace Xavier Rush. A spokesperson for the clinic said: "We are super excited to perform what is thought to be the World's first Identical Triplet Hair transplant on all three brothers." The clinic has been running for five years and performed transplants on celebrities including Ella Morgan from Married at First Sight.
