Here's why:
* Natural hair refers to hair that is not chemically treated. This means it hasn't been permed, straightened, relaxed, or colored.
* Perms are a chemical process that permanently alters the hair's texture. They use chemicals to break down the hair's bonds and then reform them into a different shape, usually to create curls or waves.
So, natural hair is simply hair in its most basic state without any chemical manipulations.
