Man #1: A man with MPB and Norwood 4 hair is taking Propecia for a year and experiences significant hair regrowth (let’s says 90% of the hair he originally lost).
Man #2: A man with MPB and Norwood 4 hair is taking Propecia for a year and experiences only a halting of the hairloss and NO regrowth of the hair he lost.
Based on these two situations, which man would have a better chance at preventing further hairloss in the next 2-3 years? One halted the hairloss and regrew hair, the other man only halted it.
Is this a trick question?
I would say Man #1 since he grew back 90% of the hair. Even if he lost more hair in the next 2 to 3 years he would still be ahead of Man #2, but I don’t think that is what you are asking. In reality there is no way to predict hair loss. It is mostly in the genes. Some people may have drastic hair loss at a certain age just because they were meant to as it was written in their genetic makeup.
To put it another way, you cannot predict when Man #1 or Man #2 will die just because they lived healthy lives.
