I'm 17 years old, and I've been noticing a lot of shedding for the past 2 years, I talked to a doctor back then and she said that it is normal to lose 50-100 hairs a day (which I didn't know before) both my parents have not experienced significant hair loss. And my hair overall looks thick, but I can't tell if my hairline is normal or if I'm experiencing an early stage of male pattern baldness. I am worried because I can see a lot of my forehead, and also it looks like its somewhat making a male pattern baldness shape.
