The Razzberry Red is a stunning shade that adds a bold yet natural look. My hair looks vibrant without being too intense. Applied once a month, it stays looking fresh for weeks. Easy to use and doesn’t leave any residue.

Great value for the color intensity. The 3 oz size is enough for a full head of hair. I noticed no dryness or frizz after use. Perfect for a subtle red pop without over-processing.

The color is nice, but it faded a bit after two weeks. I think it might be better suited for lighter hair types. Still, it’s a good option for occasional use.
