Yes, way to go cocojambo.
Definitely meet with a hair transplant surgeon and get checked for Male Pattern Baldness. Hopefully you don't have it. If you do, then find out if you can get on Finasteride at 16, yes it's pushing at that age, though you should be fine like most who get on the medication at that age.
Balding can start at 14/15 years of age, it can start as early as age 12 in humans from what science has proven.
I'm hoping that I'm not suffering from male pattern baldness but the hair falling in such big amounts in the shower and the presence of white(miniaturizing?) hair around some parts of the hairline is kinda discouraging me.
I'm not afraid of the side effects from finasteride as a 16 years old as I'm afraid of it stunting development during puberty.
