Often, we think we shed a lot more than we do.
Losing 80-100 hair a day is normal, imagine if
you don't wash your hair every day, don't brush it out,
or if its longer hair tends to fall off and get tangled
with other hair, how many hair will find itself in the shower
even normally, A LOT.
The reason for dutasteride or finesteride shed is that for some
weird reason it pushes the already damaged hair towards dormancy
(the hair's stil very much alive). Within 4-6 months, those reemerge
and the density goes back to at a minimum the one you had before you started and then goes up from there or at a minimum stabalize.
The very front 1/2 inch of the hairline is incredibly sensitive to DHT in males and females and even cutting off DHT entirely is no garantee that this small part would come back.
When you said you lost hair at 21, do you mean lost from the mature male hairline, which even in males with no significant male pattern baldness is 1/2 inch behind their pre-puberty hairline with a slight diminution of density at the temples (many women also have this). Like I said, that initial lost is very hard to get back, but cosmetically it doesn't really make a difference unless your natural forehead was very high to begin with, since there's plenty of women with much higher foreheads naturally than that.
