Body hair and scalp hair and is a different animal. That’s why studies with mice where some substance makes their fur grow (or stop for that matter) are pretty much useless for human male pattern baldness which we try to solve. And it’s really common to se increased body hair in mpb, especially on chest, back, shoulders.
True. Just sharing my experience.
I am in the middle of self experimentation and i will report the results here after 2-3 weeks.
