I need to join Colorholics Anonymous myself!!
Now that I found my holy grail color with T & T Bronze, I'm ashamed to admit that I've turned my color fetish on my daughter!!
Last weekend I actually let her buy the Herbal Essences Highlights kit
, it was supposed to give Copper highlights, but since her hair is so dark, I figured it would probably only lift her hair to red... Well, when I got home, I did a strand test on some hair that I got out of her comb... Granted that I left it in the solution for about 30 minutes, but her hair turned damn near WHITE!! That's some strooooong stuff!!
I did another test later, leaving the hair in the solution for just 10 mins., and sure enough, it lifted to that coppery color!!
We decided not to use it. I didn't want to take any chances with her hair, since she's trying to grow it out!! We took it back to WalMart and I ended up getting Loreal Casting ColorSpa in "Redwood" which came out really nice (a deep auburn/wine color), and her hair looks even healthier than it did before we colored!!
*edited to add* -- I forgot to mention that when I got home and read the directions for the highlights, it specifically said "not to be used on relaxed hair"
