Is the chlorine in municipal water likely to speed up MPB in those that are predisposed to the condition?
Chlorine has been in use with public water since the early 1900s to kill disease-causing pathogens. I do not believe it speeds up balding. Male pattern balding is caused by a gene you inherited. It impacts men with different patterns (thus term “Pattern”) and different severity. Most of the hair loss happens to men in their 20 and 30s. Aside from the genetic predisposition, anabolic steroid use can sometime speed up the process.
