Wouldn’t mess with any of it. No shampoos/conditioners, no saw palmetto, no Finasteride in any shape or form. Again, you’re on a PFS forum asking advice on whether to take anything for your hair… not much more needs to be said lol.
I’d wager that many guys here would blindly trade places with you without never having met you or known your life circumstances.
To stop the hair loss, you’re gonna have to fuck with DHT. That means tampering with hormones and receptors. That means putting yourself at risk for a condition that we know virtually nothing about…
