my hairs been thin forever, I got a hair cut as a teen when my hair was long and thick and all of a sudden the back on my neck was really thinned out and my hair dresser was worried, she thought I was sick. I did blood work etc. and nothing came back. My hairs been fine since, just thin. It goes it spouts of being thicker and thinner. It’s been good this whole year then in the last 3 weeks or so just took a nose dive down for the worst. I was using Nioxin which was new for me, so I’m wondering if that could have been the problem. Regardless, I knew I had thin hair anyhow and was looking to go on finasteride. but have been doing a lot of research the last week, and now I’m 95% sure I have DUPA, which explains things. I’m adding pictures to see what others think. I just want advice as to if that’s the case if it’s worth it to go and still get finasteride. And try and do anything to help it. Don’t realize how much this stuff takes a toll on you until it hits you, but man it sucks. Only 25, no generic history of family hair loss or anything in my dads side, don’t know my moms dad though, never met him but he’s the only thing I could possibly think of.
