How would you classify Andrew Lincoln’s hairline?

Andrew Lincoln, probably best known for his role in The Walking Dead, has a hairline that looks very straight (possibly due to styling or Hollywood “magic”) in some photos, but in other photos his hairline looks like it could be a Norwood class 2 or 3. Your guess is as good as mine without seeing his hair wet or up close.

In some photos, it almost looks as if he is wearing a hair replacement system.
I thought so too, Robert. At other times I thought that he just had a naturally high hairline. The wrinkles on his forehead go pretty far up, and a normal mature man’s hairline is about 1/2 inch above the highest wrinkle (or so says Dr. Rassman, at least I think). In season one of Walking Dead, it as cut very short and revealed much more of his forehead and back then I thought he was a norwood two or three. By the end of season two, there was quite a bit more length to his hair which of course made it look fuller. But my guess was the same as the Dr.’s: norwood two or three.
Andrew Lincoln most certainly wears a toupee on that show. Now that he wears a longer hairstyle, you can see a pronounced difference when wet from perspiration, etc.
