I LOVE THIS SHAMPOO. I have stopped coloring my hair and the difference between the grey and the blond was looking so tacky. This shampoo blends the grey into the blond for me so there is not a harsh difference where the two meet.. it tones both the blond and the grey and makes it look like it goes on the same head of hair. I was honestly thinking of biting the bullet and dying my hair again... now I don't have to. I love this shampoo.
