Home Bargains have Jo Baz.
I prefer jo baz purely because I'm a cheapskate but I think there must be something wrong with me, I can never smell it on my hair afterwards... maybe it's because I'm so anal about rinsing it out?! I'm literally there for about a day washing it, haha
I found it!! That Jo Bazz in home bargs! My bf had no idea how excited i was lol!
I've used neither Colour B4 or Jo Bazz but the Superdrug brand one isn't bad imo.
Of course, I don't really have anything to compare it to xD and my hair was stained with the red dye. But it did work! π
I don't really know which I prefer because I've had some good and some shady results with both. I'm inclined to say jo baz lifted more colour out than colour b4 but I've not used the latter in ages so I can't reeeally rememeber.
I have noticed that there is an increase in the number of these products available lately... I saw a couple of new ones in Boots today that I'd be interested to try out...
I have a new one that I'm planning to try. It's by Kenra and it's a non-bleach color correcting system; and I'm not sure if those of you not in the US have access to it. I'll post a link to the product (I hope that's okay):

I have some to try. I had dyed dark hair that had been highlighted underneath (ombre). When I first dyed my hair, I used a highlift red on my whole head of hair. Since highlift products won't budge the dark dye, it looked like I had lowlights mixed in with the red, and was actually kinda pretty. My new growth is now about 2 1/2 inches long, and so the look of lowlights is no longer really looking good. It's looking more like grown-out color mixed in with my red. So. I thought I'd try this product to see if it'll budge the dark dye that's left in my hair. I'll post a review once I'm finished... likely sometime this week. π
