Why is a dirty braid called a dirty braid? Is it because it is dirty?

Early dirty braids are particularly dirty. Africans use mud, honey and even animal droppings to fix their hair. This history is too long, they can learn science by themselves.

However, today's dirty braids are no longer dirty, because the technology has been upgraded, and dirty braids are no longer preserved by natural reproduction, but are crocheted with special tools for dirty braids.

We think that the reason for dirty braids is mostly because some people who leave dirty braids don't pay attention to personal hygiene, which leads us to think that dirty braids are dirty, but in fact, dirty braids are not dirty.
