When you think about the mundane elements like that, Who cuts Tarzan's hair? How does he shave?
If he was brought up by great apes, why would he bother?
Cheers!
Tarzan learned to shave using his "claw" the long dagger he found in the ruins of the hut where his parents died and which he had used to kill the alpha male ape that had killed his father..
IIRC he took to shaving because the Africans he encountered had no facial hair. Most primitive people don't shave but prefer to pull each whisker out with tweezers made from sea shells. The Romans and Greeks did the same though in areas where volcanic glass is common barbers made single use razors by chipping away a slender piece which naturally formed an edge sharper than any steel razor.
He also almost ate the first African he encountered, going so far as to roast some of the flesh, but his instincts would not let him continue.
Before encountering white men he just hacked away his hair with his "claw" a bit at a time when it got in his way. He learned proper grooming from a Belgian officer he had rescued. In later years he spent more time in civilized settings than in the jungle.
