Query: Great tips!

I've been keeping my eye on this book online and finally purchased it. It's an easy read, I was able to get through the book in less than 2 hours.I found the book has a lot of great advice and has made it much easier for me to take care of my curls. I'm too curly for straightening my hair and besides, I don't want to straighten it.I think the best thing about this book is what to look for in the ingredients of products you purchase. Looking for the bad stuff is great, it makes it so much easier to know what products I shouldn't buy!The only thing I disagree with on this book, is that I think she left out a critical step for curly girls that have been using silicone based products for a long time. I felt it was necessary to use an anti-residue shampoo to remove all the build up I had on my hair. Once the buildup was removed I noticed that my curls sprang to life more quickly and the conditioner I was using started making a difference.
