If he's NW3 then I'm NW4. @Dev5678 You are like NW2.5, Our hairlines are very similar. I would get on finasteride. Also do yourself a favour and drop the glasses, throw out the turtle necks and grow some stubble.
You are a great face shape... if you grew a very short beard, it would move the eye away from the temples. That forelock is killer, you could probably get away with another year or two without doing anything else.
They do make hair systems that are frontal units only, if your crown is intact.
