While I think this book is a great jumping off point for someone who has recently gone natural, (as far as rudimentary information and different techniques to try) I feel as if this book was mostly just Chicoro describing techniques that worked for her own hair.
Nothing she talked about was backed up by any kind of source, nor did she attempt to cite any scientific basis for any of the information she presented.
Frankly, the book is good for beginners, but for a more seasoned, well-informed natural, this book serves as little more than a moderately interesting pamphlet.
With more people becoming aware of natural hair as a viable option, and more information being publicized in regards to it, she's going to have to do better in order to compete.
