I'm not too sure about Deva stylists but I read an article in an Aussie magazine recently about curly hair. The guy, Anthony Nader, really sounded like he knew what he was talking about. Here's another article of his. His salon is in Sydney.

That's the good news. The bad news is that I looked at his website and it says a cut from him costs $650!!! That can't be right!?! It says a cut from a senior stylist costs $70 though.

I haven't been there myself but it might be worth calling them...
