Fifty minutes? Wow. I gave up on NI because it wasn't covering my gray, but I was leaving it on only 30 minutes. Maybe it's worth trying again. I don't care that it fades quickly--I'm having to go to the salon every 3-4 weeks as it is. Coloring at home is such a pain, but paying a stylist $$$ to cover gray roots is more of a pain.
I had a terrible time getting a NI shade that didn't turn out way too dark on me, though. I kept going lighter and lighter, since matching my natural color (dark brown) gave a shoe-polish effect.
