@mircurls and curlypearl

I think i have really similar hair to you both maybe just a little more coarser... My curl pattern is more tight at the nape (the back of my hair in general)... Can u tell me what all these acronyms for products are please... Im unfamiliar with this and Im really interested in what both of you have to say since I feel our hair types are similar .. Btw can u explain to me what porosity is and how i can figure my hair's porosity out
