Fantastic product!
Love this conditioner, I got some of this for Christmas and wasn’t too sure that I would want to continue with such a pricey conditioner. However, it’s made such a difference to my mature, coloured, tick hair, that I find myself reordering it. My hair is soft, shiny, bouncy and lasts longer between washes. Also, I find that I don’t need to use a separate conditioning mask. You also don’t need to use too much, so it lasts quite a while.
