I heard about Ted Gibsons product line recently and had to try it. Basically there are color deposits in the shampoo and conditioner. It's available in blonde, brown and red. You shampoo and condition like normal but let it set in your hair for 3-5 minutes. At first I didn't see much of a difference but the second time I saw more of the color was taking. My old highlights that looked brassy now had more of a light brown color plus in general my brown was shiny and looked much fresher. I am very happy with the product and will keep using it. I bought mine from dermstore, and it was around $25 per bottle.
