loreal feria hilift

Just passing on a warning/story:
I was in the hair color aisle and a woman told me
that she's been dying her hair for years but that the L'oreal Feria Hilift turned her hair gray and she had to correct it. Just FYE.
I always seem to hear bad things about feria. Does anyone else agree/disagree?

I really want to try feria hi lifts because of my current situation:
I tried putting in purple streaks in my hair, didn't work so on my naturally dark brown hair i put black in to cover it up. that worked until my roots came in then i tried going lighter, and my roots turned gray! then i tried black again. Then my sister had the idea to bleach my hair with a blonding kit and that made my hair 5 different colors: blonde red orange brown and black. AHh then i tried dying back to brown which turned my hair a burnt orangish. Now i am currently back at black and i hate it!! all i want is my natural hair back. Should i strip it, or use feria hi lift???? HELP!!!!!!!
