I really dont f*****g know anymore lol...i just got a good look @ my little bro's head..he is a perfect Nw1 obviusly being a 13 year old...but his hair when buzzed ALSO seems to have a super thin density but only on the top of his head...theres no way hes balding yet...(then again I heard my derm tell me that in VERY rare cases men start as early as 11 years old AND ITS BEEN DOCUMENTED) espeically among the crown my bro has very see through hair. I dont know if im supposed to think that we just have very low dense hair, or we're aggressive balders.
