Clairol Natural Instincts is a semi-permanent that works well and makes the hair really soft. Unfortunately, I used midnight black on top of my already jet black hair and it became somewhat permanent. Since I plan on going lighter, I have discontinued use but it is still a good color.
Jazzing and the one in the burnt orange bottle (Beautiful Collections, I believe) went right down the drain and did nothing to my hair.
I liked Adore but it didn't color my gray (yes, gray
erplexed).
Just recently tried
Ion Color Brillance (gray bottle, purple top) from Sally's and
it. It doesn't look like color sitting on top of my strands, it actually looks very natural and made my hair really soft.
