Okay, i took a pretty big plunge everyone! The special effects fishbowl had faded to a minty-silvery-blond color, and of course the atomic pink had almost not faded at all. I bought a box of clairol natural instincts #36 midnight black. I didn't realize this was non-permanent until I got home. The result was a pretty intense raven black color. I'm not sure how much "better" it is than a permanent dye, but nothing has gone wrong so far!(except for some color bleeding)
On a side note: My hair feels very healthy now thanks to that Garnier 3 minute deep conditioner that i picked up the other day. It works wonders, and I really recommend this product!
