RU protects your hair follicle from DHT attaching to it where you apply it, but it leaves your body’s DHT levels COMPLETELY IN TACT.
This means that you still get all the benefits of DHT circulating in your body like muscle hardness, increased muscularity and fat loss, zero libido or erection issues, etc.
At best – some other hair loss prevention treatments such as Finasteride or Dutasteride will significantly halt (or noticeably slow) the miniaturization process and, if you are lucky – provide some not-too-significant regrowth.
Finasteride and Dutasteride work “great” for the majority of guys who don’t use steroids and are lucky enough to not crash their systemic DHT levels so hard that they end up with erectile dysfunction, brain fog, and a fatter less muscular physique.
Testosterone converts to DHT in the body, and as men have a much greater amount of testosterone in their body than women, it consequently (and inevitably) leads to extreme hair loss in those who are prone to male pattern baldness.
