19, balding? should I start finasteride or dutasteride

[fapr]

Hi guys I’ve noticed my hair getting thinner and thinner for about a month. I’ve always had a big forehead, but I feel like my temples and hairline are receeding. Also my hair on the crown of my head is very dry and thin almost crusty. I’ve always had long healthy hair, my big brother (25) has healthy thick hair and my father (56) has a perfect hairline, so do his 4 brothers (all older than him. My mom has good hair...but her brother (my uncle) is bald af...he told me he started to go bald in his 20s. I look exactly as my father did when he was my age, im literally his clone, and all my life I’ve had his same hair, but is there a chance I’m the only one that got my uncle’s hair gene? I posted some pictures down below to see if you guys think I am balding and what norwood do you guys think I am and if I should start taking finasteride or dutasteride, thanks
