- Most cleansers were too harsh to use on hair, or too expensive to use often, which is why they didn't wash their hair often
- This is also why people with long hair kept it up and covered. That protected it and kept it clean.
- Frequent combing and changing hair coverings not only keeps outside contaminants (dirt, smoke, bugs, etc) away from the hair, they also do a fair job of evenly distributing the natural hair oils and removing the excess.
- Given the resources they had, they did a pretty good job.
