i think keto is quite ok in this job,
also topical finasteride i think also has a job,
ive recently dropped it (was included in minoxidilmax 15 dualgen) after about 3 months of use, and i noticed quite some shedding and thinning - like i havent had in a couple of years i think (though the hair pattern and all looked wierdly the same).
gonna get it again anyway,
im very intersted about other stuff like topical dutasteride and others, but i dont know their effiecncy,
theres also an experimental herbal stuff that might help and its cheap so i might try it as well,
but it think you guys missing a major point here -
one could get rid of all of his scalp dht (i actually think i have done that in the last couple of years), and still not regrow any hair,
theres is something else to it,
i belive it has to do with eliminating inflammations, stress and tense and rebuilding the damage that has been done,
its like - if you have a hole in your tooth (usually from decay) - you should first clean up all the decay leftovers (equivelent to removing dht), and than you should fill it in with something, or prehabs grow the teeth back if thats possible (and i belive that it might be in some when in the future).
try checking out my thread about the salicylic acid if you want..
