Angela at the Curl Ambassadors on Harbord is great. I've been going there for over a year now and am always happy, and if I'm not happy (which is rare) they're always glad to fix it.
As far as products go, she always uses
KCKT and
KCCC in my hair as I'm not really a Deva girl, but they also carry Deva, Carol's Daughter and a few other lines I think.
