Some men go bald some men don’t. Is the reason for this the fact that the non balding man’s hair is resistant to DHT or is it some other reason like the none balding man has less DHT in his system? Thanks for your response.
The reason why some men go bald is because of the genetic trait they inherited from their parents. This genetic trait causes them to be susceptible to the hormone DHT, which triggers apoptosis (cell death) in male pattern (genetic) balding. If you do not have the genetic trait for balding then DHT does not matter.
Everyone makes their own DHT which comes from the metabolism of testosterone. When we treat a balding person with a DHT blocker like finasteride (Propecia) we block the interaction of DHT at the hair follicle level for those who are genetically susceptible to DHT-related male pattern baldness.
