Not chapped lips, but I can't use any Colgate toothpaste. I get dry, flaky skin under my bottom lip whenever Colgate comes into contact with my skin.
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!
