Obviously there are many ways different hair types can be worn, combed, braided, cut, etc., but is natural, untouched Black/African decendent or ancestry hair an afro like in the 70s or was that styling? I imagine if it is natural, it’s normally like any hair cut shorter to make it easier to manage so that’s why one might see many lengths?
Not too many Bushmen with afro picks. Honestly my first guess would be dreads. Probably would greatly depend on the kind of tools available since the timeframe would be extremely long.
