I can't even remember who originally thought of it. I've been wanting to try myself, but just haven't gotten round to it. Where did you find yours?
I'm a 3b, with 3c underneath.
Used to be CG, now I'm not. Using Suave Aloe & Waterlily shampoo & condish, JoiWhip, BRHG, Suave Aloe gel, Aussie Tizz No Frizz, and anything else that looks good!
