"his front hairline alters continuously going up, down, recessed, straight across and even a widow's peak, all of which is documented."

It's called hair styling. He has never had a widow's peak except when the hair has been cut short and styled forward, ie. it was cut/styled into that shape.

His hairline has remained constant when exposed with only very mild recession over recent years which is now starting to progress (a BIT).

His crown is a little thin when he buzzes it now, but that is just early balding. When he grows it out it looks thicker because he has an insanely high natural density to begin with and everything else compensates. Maybe he's adding concealer too now, but I doubt it - he wouldn't even need it yet based on his minimal recession/thinning.

If there was ever anything 'fake' looking about his hair in the 90s it was just how ridiculously dense his hair has always been. That's just luck though. Some guys have that.
