Things that make a man healthy like heavy lifting, eating healthy fats and being in the outdoors all lead to increased testosterone which leads to higher DHT levels. It sounds silly but to always think about how your activity may affect your hair is a real pain in the ***. I've even seen some people suggesting eating soy products to lower DHT levels, basically feminizing the body and making everything weaker to save the hair strands on the head. I just wish they hurry up and make legitimate treatments for this stuff already so I can go back to lifting heavy weights without worrying about going bald.
