I came out with Loreal Excellence HiColor Highlights in Magenta and a 20 volume developer. I was doubtful at first but the 'For Dark Hair Only' gave me a glimmer of hope. The result: AMAZING.
I colored the bottom section of my hair. The color was VERY vibrant at first. While the box was labeled 'Magenta' it came out red. Like, fire hydrant red. I was a little upset but still liked it none the less. The color continued to wash out of my hair for awhile. It ended up fading to a magenta color after seven or ten washes and I loved it. Once it settled down to that color it stayed. No fading, no dullness, nothing.
Yes, this is the best picture to show you the color.
No, I did not take the picture seriously.
Also why my man is leering in the background.
No shame. :]
The color stayed until I dyed over it again with dark brown (at least 3-4 months). So, my final satisfaction rating. HIGHLY SATISFIED. The color itself cost about $5 which was much cheaper than other boxed dyes. A 20 vol. developer cost $4, another great deal for the amount. Both products were bought at Sally's Beauty Supply Store.
