I'm going to have to go the bookstore. Dickey seems really positive:
Hair Rules! is chock-full of simple tips for all types of curly hair and covers everything from the best shampoos and conditioners to use, to damage-free hair-drying (dust off that hood dryer!), the use of natural oils, and the safest coloring, styling, and chemical relaxing techniques, as well as guidelines for maintaining healthy, gorgeous hair.
"My mission," writes Dickey, "is simple: to advise and encourage all women with non-straight hair to strive to attain their beauty, whatever their ethnicity, and whatever their tastes."
