I am selling a brand new copy of The Science of Black Hair, by Audrey Davis-Sivasothy. As a recovering product junkie, I am willing to admit that I bought this book because of the popularity, however, this is one of many purchases during my bouts of product "addiction." It is definitely a comprehensive guide for women out there who would like to better understand thier natural textured African American hair. Especially those who are fairly new to the natural hair movement. If you're interested, don't hesitate to reply. (I will not sell the book for the original retail value.)
