My hair loves most of the deva products! I have never had a problem with the Angell, never tried ArcAngell. In fact Angell is my HG!
I switch off on condish from One C to L'Oreal Vive Pro Hydra Gloss Moisturizing Conditioner (yellow bottle). I shampoo with Devacurl No Poo.
My curl's kryptonite is wheat, soy and silk proteins.
