So, I don't remember where, but a few years ago, I read something that said that testosterone was a big reason for hair loss and that saw palmetto was a good "cure."
I do know that saw p is a good "cure" for prostate, but don't have that issue.
Anyway, used the stuff for two years, no result. Read something else that said that beta-sitosterol actually worked better than saw palmetto for prostate problems.
Decided, what the hell. I tried the Beta Sitosterol. Been using since November (it is now March) and have a big improvement in both thickness and "regrowth" of lost hair. And gray color seems to have toned back a bit and more black.
Anyway, seems to have worked for me.
