You have several questions regarding why human head and beard hair keeps 
growing in a biological sense, but how would this come about?  What 
evolutionary advantage would this create?  And how did primitive man (before 
the creation of knives, etc.) manage the long, tangled mane atop his head and 
on his cheeks?
