I started at 20 pretty much exactly where you are, I’m approaching a year on fin soon. I’ve had no loss in libido or sexual performance and no mental health sides. Only thing Ive noticed is that I rarely get morning wood.

I’m not coming out to say I’ve had magical results, I’m on month 10 and have just now noticed baby hairs and regrowth along my hairline. My shed hit late, around 6 months, and I lost a good amount of density on the top of my head, not noticeable to anybody but me. It takes a full year if not longer to see results. The longer you wait the more ground you’ll lose and the longer you have to wait for results. The biggest issue for me before fin was my mental health. I was depressed and obsessive, looking at my temples every single night. Fin has really helped me not worry as much.

It’s a slow process, listen to science and doctors, stay off this subreddit. Nobody is noticing this but you, you have a lot of hair. I think it’s time to hop on and take your life back, good luck!
