I actually got into curly girl via the instructions on The Curly Girl Method
without knowing the history behind it / book / etc.
Now that I read more about it (here and other sites), it appears that there are small variations here and there.
Having said that, I'm just writing to say that it works - HOWEVER - as others have mentioned, and this is crappy news for the impatient, it takes TIME
Good luck ladies
And if you're thinking about curly girl / no poo, I highly recommend it - just give it its paces and I hope you enjoy the results.
