The singer Sam Smith has revealed that he has had a hair transplant in the last two years.
You can see the difference in his appearance in the two pictures below.
The one on the left, taken before his hair transplant, shows the star with thinning hair and bald patches at the front of his hairline.
In the picture on the right, taken after his new transplanted hair had grown back, the bald patches are filled in and his hair looks noticeably thicker at the front.
Sam has got a great result.
He spoke about his new look in a video interview on the Vogue website.
He explained: "My hair has been a touchy place for me. I haven't spoken about this before, so I'm gonna speak about it because I don't actually feel like I have anything to hide.
"I have had hair transplant surgery. How stunning is it?"
Sam said he had sought help on the advice of his hairdresser.
He added: "It's nice to have hair, but also if I was bald I would still own it, too."
Sam first mentioned hair loss in a 2017 interview with the New York Times, saying his hair “started falling out from stress” following the Oscars ceremony that year.
At the time, he credited the drugs Rogaine and Propecia for helping regain some thickness, adding that “men need talk about hair loss” to combat stigma.
Sam, best known for his international hit Stay With Me, is only 28 - relatively young to have a hair transplant.
However, inspired by stars such as Wayne Rooney (who had his first hair transplant when he was 25), increasing numbers of younger men are seeking help earlier to combat male pattern baldnesss.
Before that, it is very difficult to establish the pattern of the hair loss.
Operate too soon and the patient can be left with patchiness where the natural hair falls out.
After 25, for most patients the pattern has been established and it is possible to bolster the hair very naturally with a hair transplant.
Sam would have almost certainly had a FUE (follicular unit extraction) procedure. This is where donor grafts are extracted individually from the back and sides of the scalp and replanted in the balding areas.
The advantage of FUE is that the scarring is minimal - perfect for a man like Sam who likes to wear his hair short.
Famous FUE patients at Crown Clinic include the Coronation Street star Jack P Shepherd, model Calum Best, Homes Under The Hammer presenter Martin Roberts and the former footballer Didi Hamann. Around 80% of Dr Shahmalak's patients at Crown Clinic opt for FUE.
Whatever method Sam Smith chose, he has transformed his appearance with the transplant. Well done, Sam.
