It's just sh*t reporting from the Sun as usual.
He's still a NW7 because he had his hair transplant done by a UK butcher, so he only would have ended up with a few dodgy 80's style "plugs" on the temples anyway. Probably he was a NW4 at the time, not on finasteride, and the rest receded away anyway. Some UK hair transplant's really are this bad - laughably bad. You go from bald to having literally ~100 hairs randomly scattered on top.
You can see in his second picture some "bits" on top.
The word WANKER (you can barely make it out the scarring is so bad) is on his left side donor area, the Sun has just gotten confused as it always does. They either think hair transplants give you back a perfect NW1 4" long a week after surgery, or that people would actually pay for ANY hair even if it is a strip round the sides. (it's like when they write about IT subjects, they get the terminology laughably wrong and show a complete lack of knowledge). The writers in UK tabloids are probably as bad as UK hair transplant docs tbh.
The donor just grew out as normal and covered it up. If you look at the bottom bit of shaved hair you can see further FUE scarring. Was the punch size an inch in diameter? Butchery.
