The digital book (got it on my iPad) was what pushed me to begin the natural journey. I liked the videos a lot because I am a visual learner. However, I wish I had found this site first because this site is more scientifically specific. The book makes it seem as if you stop using silicones and sulfates your hair will be great (which is partially true), but it's more complicated than that (as we all know). However, on a personal level, I treasure the book because it opened my eyes to being natural. But this site has helped me figure out my hair needs, if that makes sense.
