Its funny because this post just made me realize that I am mostly a 4B or probably a 4C in many parts of my hair. No wonder my hair looks nothing like anyone's fotki's. Thank you CurlyNikki! I never understood the reference to z shaped curls until I read the post that you referenced. I have plenty of z shaped curls in my head. I just assumed they were curls that curled on top of each other. That is important for me because it will probably save me LOTS of money from trying the wrong products. I have been visiting the beauty supply store every weekend since I joined this site (LOL). You guys are VERY informed so I will definitely stick around.
