Well i'm 17 about to be 18 in 1 month. I started noticing thinning on the sides of my head. More so on the right side. Never on the crown though. I was misdiagnosed with cancer about 4 months prior and that put me through a lot of stress. my hair started falling out. I was noticing a lot of hair loss couple of months after the misdiagnosis. I don't lose much hair at all anymore. I lose about 10 in the shower. But at the same time i feel like my hair line receding. More so on the right than left. I've attached pics of my hair line with my hair up.
