I would start finasteride, I've had absolutely no sides from it. Also start nizoral 2% shampoo 3x wk, you can also try minoxidil 10-15% which you can find online. Dermaroll 2x wk to help the absorption of what ever you decide to use topically.
Currently using minoxidil 10%, nizoral 2% shampoo 3x week and just restarted finast this week. Stopped both Dutast and finast several months ago. So I guarantee it's the trinov because that's when the growth began. I have absolutely no reason to lie.
I've definitely positively seen results, don't give a sh*t what anyone says. I have nothing to gain either way, I posted pics in the main Trinov before and after post.
Actually I'm wrong first pic was about 4 wks, so now it's been 6 wks. Just had major shoulder surgery so can't really think straight. Those are new hairs I have no reason or benefit to lie. This stuff began working quickly on me and my hair and nails grow fast.
First pic today, second pic about 2 wks ago. Been on for about 4 wks. I didn't take a before pic which was stupid. But I def think there's a difference.
