I need some help figuring out my porosity so i can hopefully find a hair twin. I read Live Curly and it talked about feeling your hair and if it's very slick it's low porosity and then as I was reading these posts someone said something about hair floating and sinking. Can someone please tell me what that's about? I think my porosity is low, but I'm interested in the floating/sinking hair theory.

Thanks and sorry this is so long.
