I love this book. It is not hype and my sister has been doing this for years, lol. I've always tried to wear my hair naturally but it would always puff out. Now, I'm relaxer free and loving it. The freedom of not worrying about getting my hair wet is more than I could ever explain. Plus, I don't have burns on my hairline and in my scalp from relaxers anymore. The information about products is a good enough reason to purchase this book. Who knew it would take almost 30 years for me to be FREE!! Thank You again Teri...
