There's no exercise you can do to fully address dht-driven male pattern baldness. However, having strong cardiovascular health will help your body's ability to pump blood which delivers nutrients to your scalp and hair follicles. So, moderate cardio, which also helps reduce baseline cortisol levels, cortisol exacerbating test to dht conversion.
Other than that, you can do scalp massaging which i guess is a kind of exercise, which helps bloodflow in the scalp, and relieves stress, and helps hair health. Actually there's a muscular tension theory of hairloss relevant here you can look into based on the fact that a map of chronic muscle tension in bald people matches pretty exactly a norwood pattern.
Doing headstands and shit i guess. Suggestions getting pretty stupid now.
Nothing beats fin/min. Especially fin.
