Hair loss is caused by androgens. DHT isnt the only androgen. Block all androgens and you stop hair loss. Its as simple as that, but some people are not willing to do that, because of certain sides.
If you dont agree with taking drugs for hair loss, then leave. Hair loss progresses in a similar way to prostate cancer. You cant simply use natural remedies to treat cancer, neither can you for hair loss.
Either you modify your hormones/effects, or you accept your destiny, shut the f*** up and let people decide what they want to risk for hair, and believe me, you dont know its value until you loose it.
Nothing is delivered on a silver plate. Risk and reward is the name of this game, game called life.
