I’ve seen that you say only 7% of balding men will hit stage seven on the Norwood Scale. What about stage six? Theoretical if there were no treatments would most men (93%) be destined for stage six on the Norwood Scale? And is whether or not you reach seven on the Norwood scale genetic?
This is not an easy question to answer because of judgment problems in those that wrote the original charts. The best statistics I could find indicate that the Class 6 and 7 patterns in men over 50 years old are present between 23-30%. Assuming that the Class 7 pattern is 7%, then the Class 6 pattern is twice as common.
