Rated 5 out of 5 by from Great line This developer pairs perfectly with the iNOA color system and gives very consistent, reliable results. I love how gentle the formula feels while still delivering excellent lift and color saturation. Keeps hair smooth and healthy and clients love the added shine and softness after their service.

Rated 5 out of 5 by from Thick This developer worked great with the color line. It’s thicker than a regular one. But this is an oil based developer.

Rated 3 out of 5 by from Just Okay I was given this product for free for an honest review. This developer is a little thicker than most developers that I have used in the past but I think that was due to it being oil based. No heavy scent which was nice. It mixed well but I can see issues if too much developer vs color is used. Overall it was just okay.

Rated 4 out of 5 by from Creamy developer Very thick developer, but it mixes well with the color. Very creamy. No odor.
