I am literally a mix of all three lol.
1. Lower two thirds are good, I have good bones there. But my egg head shape ***** my hair and my neck is stiff. My posture sucks
2. I started diffusing when I got hypo.
3. I started balding more rapidly when I lifted hard. I also got more calcified in that timeframe. Those forehead veins could have been mine.
I'm having some progress by fixing 1 with yogaish exercises, 2 with peating, and 3 with an anti calcification protocol and stopping to lift as excessively. So there is ***t that can be done
Great pictures, especially the top one. The anatomical details of the scalp are fascinating.
It's a shame what happened to Brendan Fraser. He obviously went through some tough times.
I grew up on those Mummy movies.
Personally though, I don't think they're totally separate forms of hair loss. Most guys experience diffuse shedding to a relative degree but they have thick hair so it doesn't get as bad.
Even diffuse hair loss can eventually evolve into typical MPB characteristics.
I think as Danny Roddy has talked about in his videos, there are multiple factors contributing to MPB. I think the initial hair loss (from parathyroid) becomes permanent with elevated serotonin (prolactin reflects serotonin levels) and then there's fibrosis.
