im 19 and losing my hair fast!!

Hi all, this is my first post.
Im an African american male 19 years old balding fast

Im pretty depressed that my hair has thinned dramatically. My hair a couple of months ago felt thick and now it feels thin every where but there's recession mostly around the middle part of my hairline when i look up i can see my scalp but my corners are okay is this normal?
There is not that much shedding actually its just really thin all over my hair,ive been using saw palmetto for my hair and it limited my shedding.

Is there a way to thicken my hairline and my hair all around?
Also my grandpa from my dads side is bald and my dad has hair at age 40
and from my moms side her brothers are bald but her dad has hair weird right

So if its genetics im gonna have to deal with it i kno
Thanks.

Get on propecia and start rogaine.
