Should I get on Propecia at 19?

My doctor said I was a NW1 and my hair loss is by far worse than yours. However, i progressed from a completely straight hairline, NW0 literally.

I would still see a doctor, messing with your hormones when you're still in puberty is not smart when not supervised by a professional.

And yes I take finansteride at the age of 19, but I had it prescribed by a dermatologist, who monitors me. Which I would strongly recommend you do as well
