NovaHair Gray Tone Shampoo

Blonde leaves the salon looking perfect and turns warm again within two weeks. At first you only notice it in the bathroom lighting, and then in photos too. It's not that the color failed. This is what happens to every light shade.

The gray pigment in this shampoo neutralizes yellow and brings back a cool look. It works in layers: the longer you leave it on, the cooler the tone.
