I use this in combination with Neuma's reNeu shampoo. My stylist explained that I only needed to use this on the ends after using the shampoo, which is incredibly effective as is. It cost about $30 for the bottle, but I think this product will last me a very long time - I need less and need to wash less often. The smell is amazing, the weight of the conditioner is light, and it leaves my hair feeling incredibly silky. As I often get split ends and am let down by hair products, I was skeptical. But this conditioner is working so well, keeping my ends clean and keeping my hair feeling bouncy without getting greasey very quickly! Highly recommend.
