massive hair shedding from scalp and body

[aidin91]

Hello,

I am seeking to find the cause of my hair loss. it is really confusing since I don't know why I am losing hair, all the bloodwork is normal everything appears to be normal but my scalp becomes visible on sides and top,my sideburns are lot thinner than before and all hair on my body thinning from 4,5 years ago when I was 18,19 years old.
I really need your help guys, because I visited lots of doctor and spend lot of money but it didn't workout.
Thanks in advance
