I read before that insulin plays a big role in hair-loss, so I figured I'd try out a ketogenic diet (high-fat, low-carb) diet which I did before for 6 months for weight loss. That time I didn't focus on hair as I was not losing anything. Holy ****, 1.5 weeks in to this diet I'm literally losing 50 hairs just shampooing my hair, I can pluck out 5 hairs in one pinch. It's horrible. I figured I was clever trying this relatively unknown diet, as most bald guys probably eat a basic high-carb, sugary diet, but no. I guess my body might have been shocked from the sudden diet change, and need more time to 'adapt', but rather not risk it further. Going to just do with paleo, hopefully get some benefit from the nutrients.
