Wow! I just went through this entire thread! I wish there were more pics of Type 4 hair, but oh well! You ladies have done marvelous transformations with your tresses! I'm a type 4 (I think I'm med/normal porosity and density, still working on the texture thing). I hope my curls/waves/whatever they are POP too!
Texture: Coarse?; Density: Med (?); Porosity(?? Med-high); Wave pattern: 4B coils
