Dry hair full of grains

I'm a huge fan of the body shop's ginger shampoo and conditioner, so when the Ginger Hair & Scalp Scrub came out, it seemed like a logical purchase. Unfortunately, the product really disappoints me. I'm not sure what the scrub consists of, but it doesn't melt away like most scrubs. You have to rinse everything out, which is very difficult and takes a long time. On top of that, the scrub made my hair feel very dry, which only made it harder to wash out.
