I'm such a rule follower that I do not intentionally break any CG "rules." There was the accidental sulfate or silicone early on, but nothing lately.

My biggest CG oops was the first time I tried coconut oil. I didn't know much to use, so I saturated my hair with it. I had greasy looking hair (with really well-formed curls) for three days. I had to use dish soap, lemon juice, and ACV to get it out.

No silicones/no sulfates since March 2008
