Why do men grow bald?
http://sciencenordic.com/why-do-men-grow-bald
Loss of hair and the natural type that so many men experience is androgen, meaning it’s caused by steroid hormones.
This differentiates it from other types of hair loss that are attributed to disease.
Enzymes in male bodies convert testosterone – the principal male sex hormone - into dihydrotestosterone.
Dihydrotestosterone is a hormone that, among other things, makes hair shorter and thinner.
Scientists think Asian men have less of this enzyme in their follicles, which is why they are more prone to keeping hair than Caucasian men.
