Dude after years of trying stuff, I can safely say that nothing natural is going to do anything, except for maybe doing some cardio exercises (I prefer bike riding), reducing stress, going outside in nice weather to exercise, and even then there's no guarantee and chances are slim. If these things do anything at all it might slow down hair loss and not grow anything back, and there's still no proof of this. I think I read somewhere that good cardiovascular health can reduce DHT in your body, generally if you reduce it will slow it down, if you eliminated (as with propecia) it might grow something back but there could be side-effects to this. These positive life choices are generally good for you even if they don't do anything for your hair, so you've got nothing to lose by doing them and they can definitely help you live a positive life regardless of your hair.
I've come to the conclusion that it's best just to try to move on and do your best with whatever cards life has dealt to you. If you get dealt a shitty hand that doesn't mean you should just give up and stop playing the game of life.
That's my (in my opinion) realistic philosophy on losing your hair..
