How did Africans started using weave?

now i know this question may seem kinda dumb, because its been around for a while, but i just want to know 2 things, 1.Where did the Egyptians get HUMAN hair for wigs from? and 2.When did modern braid weave started being used in Africa, and how? (now i know kaneka said they started selling kanekalon in Senegal, and a few other countries in the 1980s (which im guessing that's how Senegalese twists came about, and i may seem like i just answered part of my question, but how? did they just start shipping hair there and the people started using it asap? i'm clueless) plz and thank you to whoever answers! :)
