I used to use it before going sorta CG, as well as Ringlet. My hair didn't curl nearly as well back then, whether because of the 'cones, etc. I don't know.
They still use the line on me when I get my hair cut, and it still barely curls when they do
. I can go home, wash it out and use my own products, and it curls right back up.
I love its nice clean fragrance, though.
