Clairol Professional Beautiful Collection Advanced Gray Solution Semi-Permanent Hair Color, Toasted Hazelnut 6N, 3 fl oz

1. Covers gray well for 2-3 weeks. Many semi-permanents will not cover gray at all. 2. Has natural-tone colors, vs. rainbow brights. The dark browns are redder than I prefer, but can be browned down using a rainbow-bright semi-permanent green or blue as a toner. 3. My hair is healthier and shinier than when I was using permanent color. 4. Semi-permanent color is more affected by the natural hair color than permanents. My grays become lighter brown highlights, and there is more subtle variation--the combination looks more natural than even well-done permanent color.
