I get white "foam" when I use aloe vera gel for styling. Not sure why because I'm fine when I use products that contain aloe vera in them. It disappears when I scrunch with my CLU towel.

Protein is a good suggestion for reviving your curls. The other is changing up your products. Many of us rotate products just for that reason. My hair always satiated on product--even back in my shampoo/conditioner only days. I wet, use a rinse out and style every day. Seldom use any one product more then once every five days.
