What's a good shampoo/conditioner?
My hair is REALLY dry in the back. I'm currently using Matrix Biolage Ultra-Hydrating shampoo and conditoiner, and once every two weeks I use a deep conditioner..it's called Cholesterol and it's orange. My hair is really dry, frizzy, and bushy in the back, but the front and sides are fine. What's a good shampoo and conditioner/deep conditioner to use? The stuff I'm currently using doesn't seem to be helping.
