At this point, anything could be the cause I'm still trying to figure it all out though. But I think I use fairly natural products so buildup shouldn't be too much of a problem. And if this is so, I'm using bentonite clay mixed with water as a regular hair wash so hopefully it can gradually clarify any buildup left on my hair! But while we're at it, do you have any good clarifyers you have in mind?I'm kind of taking a shot in the dark here (and sorry if you already mentioned this and I missed it) but have you been using any silicone (or mineral oil or petrolatum) containing products while washing with bentonite clay? It could be as simple as build-up that's keeping moisture from absorbing into your hair. Maybe you should try clarifying and then give CG a shot. My hair gets that same awful, plasticky feeling from build up, and it won't absorb moisture, so I'm thinking that might be the case here.
