I'm not sure what that is ... how serious? What's the long-term prognosis? Is there anything I can do? Or anything I should be doing?
ok well your crown/vertex is "your swirl" of the back of your hair
by some of those pictures it looks like "your swirl" is thinning/miniaturizing
meaning your hair follicles are struggling to produce a terminal "thick" hair
but then again it could just be that pictures and your hair is fine
How serious? well your hair could stay that way for years
you did say no male pattern baldness in your family
so you have genetics on your side
but that doesn't mean that you wont ever experience male pattern baldness
Is there anything you can do? well yes
i would see an professional like a DERM or GP and get a true diagnosis
of your situation
if you do indeed have male pattern baldness
finasteride "finasteride" should do wonders for you
since it works best for the crown
worst comes to worst you'll have to add minoxidil
but i doubt it will come to that
considering you thinning/miniaturizing is very early
