Curly Hair, Wavy Hair, Combined Hair

Curly Girl: The Handbook.  A Celebration of Curls: How to Cut Them, Care for Them, Love Them, and Set Them Free, by Lorraine Massey and Deborah Chiel

This book completely changed my relationship with my hair.  I don't follow Massey's advice to the word, but her guidance has helped me think for myself and has freed me from the tyranny I grew up with from a) the 70s and b) my family.  It's worth it even if you buy it new.

This book was also very helpful for me in figuring out how to adapt no-poo and other curl-friendly methods for my particular hair.

Salons where I've had really good, happy-curl cuts:

My best technique for finding a good salon or stylist when I move, it's turned out, really has been asking people whose curly hair I like, "Where do you get your hair cut?"  Sometimes this has meant asking complete and total strangers on the bus.  Curly-headed folks, it turns out, often completely understand this and do not find it strange.  Whew.

Discussions, articles, salon finder, product reviews, how to cope with your kid's hair....  Sometimes I find the site useful, sometimes I find it annoying; I include it in case it's useful for you.
