I've read it (the previous version). Honestly, I don't think there's much in there that you couldn't find online with a little research. However, I read it after several years of growing my hair long and spending time on the LHC site, so I already knew a lot of the concepts for maintaining healthy hair. If you're new to all that--sulfate-free shampoos, CO, avoiding silicones, etc.--I think it's definitely worthwhile.
