you got a link to that?
And idk about it tbh. a lot of people look up stuff that can cause general hair loss and think it applies to male pattern baldness. like uh diabetes is one i see people bring up often. thing is the patterns of male pattern baldness are specific to male pattern baldness. hair loss from health issues is usually all over the body, if it's hair on your head you're noticing it's usually all over as well. Idk that health can cause receding hair lines and diffuse thinning. that all said I don't really understand what you mean by cardio related dht? like having bad heart health causes rises in dht or? you'll have to educate me on that.
