I got tired of feeling washed out with bleach blonde hair and got my hair done at work! We used a half auburn shade, and half red pigment mixture at the top (Matrix 7RB + So-red for anyones interested), and Pravana pink at the bottom.
The Matrix washed out pretty quickly(as expected, My hair was pretty bleached!), and the pravana did not seem to budge. Pravana is notorious for not being pretty permanent when it comes to unnatural hair colors which is why I was interested in it in the first place. I could not tell you if it's going to stain badly or not, as I haven't tried to get it out of my hair(obviously!). My coworkers said it doesn't fade very much(especially since they'd watched diluted Manic Panic come out of my hair in under a week!), but should come out. If you're interested in a semi-permanent color that you can wash daily it's probably a good choice.
After about a week, I ended up getting Vampire red, and Hot hot pink(Manic Panic), I applied the Vampire red directly onto my hair and even used heat(Purposely trying to get it to stain!) and diluted the hot hot pink just a bit.
Overall, I like the manic panic results much more than the matrix/pravana. Mainly the matrix and pravana are just a base so that my colors are more permanent, and I no longer have to bleach my new growth(I'm trying to grow my hair out! :p). After a week, it's held on much better than it's permanent counterpart. I'm also considering trying different manic panic shades over my bases(Magenta to pink anyone?)
The one manic panic downside? The vampire red does bleed onto EVERYTHING, including the pink at the bottom, leaving it sometimes a hot pink/red color! My neck also gets it's own red stains. In the long run, I'd say it's very worth it.
