When I was modified CG, my hair looked thinner because it just seemed to lay flatter. I've come to realize that my hair isn't dry and it likes shampoo once or twice a week. My hair looks and feels fuller and curlier when I poo. Maybe your hair is hydrated enough.
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!
