I still reckon the 99% of people have never even heard of finasteride. I only found these forums when my hair suddenly decided to go to crap.
He definitely does not have a solid hairline. It has a diffuse pattern to it so he is not exactly in the greatest shape like Zayn Malik.

I agree with him, first thing I saw, in your picture he is leaning forward and the light is hitting from a different angle (and possibly products and stuff in it), he is definitely a bit diffuse in his hairline in OPs link.
