Speaking from experience, he definitely hasn't had one. He just styles it well sometimes to disguise the bald patches.Must admit it’s the first I’ve heard of it and I’ve seen badly photoshopped pictures where he’s miraculously got a full head of hair but I didn’t know he’d had transplants.
Grade 0 like the rock and Jason Statham and it'll be fine. He wouldn't even need to get jacked lolI wish he'd just shave the whole lot down to a Grade 1 and be done with it. It can look slightly odd when he lets the sides grown longer - particularly as he has that weird "halo" type of pattern baldness.
