Not it's not normal, and you know it. I have the same problem and was hoping propecia would stop the excessive loss, but it didn't work. For your age your hair looks great. My hair was actually better than yours just 1.5 years ago and then male pattern baldness went into OVERDRIVE and no matter what I did nothing could slow it down. Now I have half your density.
Your male pattern baldness has just Kicked into high gear, try all you can...BIG 3, or BIG 2 with Revivogen.....do it now before it's too late.
PS: There is no guarantees in hairloss and no miracle cures....just endless suffering...try to enjoy your hair while you stll have it.
