With technology being what it is there is always advances in medicine, beauty etc however some things just haven’t reached the point where it looks 100% natural.
Saying that I must say I have seen a few people who have travelled to the far ends of the planet and the workmanship in there transplants is amazing! Sure your hairstylist may be able to tell but no one else can.
If you are thinking about doing it, research it until you are convinced you have found the right person to do it, it is permanent!
If your in the middle and haven’t made up your mind then maybe it’s not for you and shave it off after all most guys can get away with that!
