Every year for Christmas, my dad's girlfriend gives me Body Shop Shea Body Butter. I have really good skin so I never feel the need to use it, but I'm thinking about using it on my hair as a moisturizing treatment. Has anyone ever done this? I looked over the ingredients and it looks pretty CG, the only things it has are cyclomethicone and a couple parabens.

I looked up cyclomethicone and it dissolves with the right low-poo, but I'm wondering about the parabens; what exactly do they do? In what way are they bad for me, and for my hair?
