Query: If you know NOTHING about haircare--this book is for YOU

Based on the reviews I read online, I anxiously awaited the arrival of my new haircare "bible". I was sorely dissapointed when the book arrived -- filled with the obvious. There was no depth and nothing that I didn't already know. I am not a haircare professional and consider myself only fairly knowledgeable on the subject. Mama always said if you can't say anything nice about something, don't say anything at all. Sorry Mama, I just had to tell folks that this book is VERY basic.
