i want BLACK HAIR...not blue black.

I just dyed my hair Light Ash Brown by Loreal Paris Superior Preference (6A). And my natural color was a dark brown kinda black color. But it didn't look brown. And now I want to dye it BLACK...not blue black just a nice shiny BLACK color. I had success with Loreal Preference except it came out a bit lighter (or maybe it's just b/c I had natural red highlights? could that be possible) or maybe its not lighter just redder? idk. I wanna wait about a month and dye my hair Loreal superior Preference in Soft Black level 3 or natural black in 2 (which ever is blackest). Would this cover up my haircolor now COMPLETELY? or would it eventually fade out and become blotchy in places. I don't want my color to be black not dark brown like some soft blacks turn out to be.


and if anyone else has used a store brought hair product in black and it actually came out BLACK please recommend it.


and is it true that black is a harsher color on hair?

and how long should you wait before you dye your hair again.

i heard loreal feria burns out your hair. but i used loreal superior preference for the dye job i have now and it turned out good and the color is bright and has faded yet...i just don't like this light of a color on me.
