Natural Black Hair to Loreal Feria Brown?

I have natural black hair. I just bought this Loreal Feria Brown B51. It said that it works for dark brown hair to black hair.. and it's made for dark hair. Have you guys used this brand? Does it really work? How long does it last?

Natural Black Hair to Loreal Feria Brown?

well i used their purplish/plum colour. the result was not what was shown on the package. basically my hair was still dark, except that it would have a purplish glow under light. it makes your hair sort of illuminous. i like it. but the new feria claims to lighten your hair by two shades, who knows if it works. in general, black hair is very hard to colour without prelightening.
