I know the reviews on this are mixed, but I've been using the conditioner as a once a month treatment for several years now with great results. I've tried the shampoo too, but it doesn't do much to enhance the color or condition of my hair, so I find it unnecessary. For reference, my hair is a dark brown mahogany with a few reddish and light brown highlights which can lean a little brassy when my hair gets too much sun or damage in general. And besides this product my hair is all natural, never been colored. My texture is fine yet quite porous and dry.
