I too am new to all this... I have low porosity (according to NC website) I'm using Deva No Poo and Deva One Conditioner and just recently- well I haven't used it for long- I noticed that when I used the conditioner as a leave in it was fine on the first day but by the 4th day, it seemed a build up of product. I noticed white specs on my hair firstly then the curl wasn't so prominent so the next day I washed it and the curl is alot better. Does that mean I need to choose a protein free Poo and Conditioner so I don't get build up? (3b with some 3a curls/low porosity/thick dense hair) Please help!!!
