I was saying that some guys bald on their hairline but not their crown.. some guys bald both. or all 3 diffuse thinning, receding and crown balding. My dads 62 years old and A norewood 3 but no loss at all on the crown. I doubt id lose anything there, If I were to it would of started by now. Also my theory is a bit different. most of the time balding happens when your young.. if you can make it to 35 years old an not lose much hair, you pretty much done most of your balding and your scalp starts to adapt to the dht levels. If your going to go bald its going to happen in your younger years, 16-35 , also his dad is still a Norwood-2.5. he just buzzes his head bald.
