I bought Textured Tresses & found it to be way "skimpy" on useful information: lots of nice natural photos, a few style techniques were detailed but too much space-wasting "celebrity tidbits" for my taste...a few paragraphs touted the benefits of "Asian Steam baths" for superior deep conditioning, but not much else. (and all the product recommendations seem to be for ultra pricey products!) Try your local library. They'll have most of the books mentioned so far (I've found them all here in L.A. except for Cathy Howse.) I'm a natural so perhaps I have a different perspective regarding what's useful but I'd say Lonnice Bonner's 2 books, Pamela Ferrel's "Let's Talk Hair", or Ella Joyce's "KinkPhobia" were much more informative to me IMO of course!.
