[LOTR] How did all the people with long hair avoid head lice?

In ancient times, head lice was a major issue and many people cut their hair short to avoid it.

Elves don't get lice, or dandruff, or split ends, or get too oily, or get tangled up. Their hair stay perfect even after physical activity and sleeping, that's just how they roll.

Hobbits spend a lot of time grooming, and they take care of their personal hygiene, so they don't get head lice, nor feet lice.

Gandalf is a supernatural angelic wizard, so no lice there.

Now, for guys like Boromir and Aragorn, well, they are all nobles or sons of nobles, so they have servants and medicine to kill off the lice. Rest of the time they are hanging out with elves and wizards.

As for the dwarves, lice can't bite through their thick skin, so any lice that get on a dwarf's hair or beard will just starve after a while.
