I bought the book, 'Going Gray, Looking Great'. I was surprised some things. For one, the author REALLY pushes the silicone for shine. By her book, she must think that's the ONLY way to get shine. She's also very in favor of shampoo, and blowdrying. Yet she ALSO says that gray hair is much more fragile and delicate than pigmented hair! It's funny how being CG made me look at those points differently than I would have before hearing about CG. I'm still reading the book. I'm about halfway through. Of course, there's NO way I'm gonna ever blow dry OR shampoo again. I think what I'll do is apply the CG principles to the principles in her book, and get the advantages of both. Between the two, hopefully I'll have really stunning silver hair!
