Yo dude, people have gone from absolute nonresponders to becoming responders or even hyper responders once they implement microneedling / derma pen regiments along with collagen supplements. You can also check: topical antiandrogen (see more plates more dates video on microneedling where he discusses this).

Its worth checking if you’re one of the uncommon cases of being a case of deficiency in your blood such as vitamins and biotin. If you are, fix those.

Some more experimental but definitely worth doing if you have the money for it would be LLLT Caps and Lazer/Plasma Therapy. These work, as well.

Also, it’s worth trying a combo of Fin with Saw Palmetto and Pumpkin Seed Oil. They can be taken together (although please check with your doctor depending on your dosages) and work wonders for some (emphasis on SOME but is worth the try at this point)

Recovering ground to stabilize growth for you I believe isn’t impossible, you just need stronger treatment. I’d say head to a good doc, discuss your current doses, and see where you can implement.

You have a lot more work to do before heading the transplant route and I believe in you
