I made the mistake of buying Garnier Champagne Fizz without realizing that "champagne" was really a dull ashy almost grey-green color that was NOT flattering. To "correct" this mistake, I bought Color Oops which promised to take out the green tones. Well, it did do that, but it also stripped out any other color in my hair except gold. As a result, Oops is an accurate name for this product as it made my hair BRIGHT YELLOW. I'm not exaggerating, either - not honey blonde, not golden blonde - no. Yellow. I followed the directions exactly. I shampooed, I rinsed. I rinsed some more. I rinsed for 20 minutes at a time, like they tell you to. Several times. I have taken 5 showers in the past 24 hours. Still yellow. My advice to you is DO NOT waste money on this cheap drugstore "fix." You will probably end up having to pay the salon to fix your hair anyway. I know I'm going to.

Color Oops to the rescue! I did take off one star for the smell, but otherwise this is a great product with minimal damage to your hair, and cost effective as well. I touch up my roots regularly, and there was color build up on the top half of my head. The top half was a darker brown than the bottom half (normally chestnut/auburn, and the difference was beginning to be noticeable). I tried the Color Oops Extra Strength after reading the reviews on here, and followed the directions carefully. Thorough rinsing according to the directions seems to be a must according to the reviews on here. I followed through on each step of the directions, and ended up with hair that was a light strawberry blond on the crown, and slightly deeper on the ends. (So NOT me!!). My hair felt extremely dry and friable, so I followed the Color Oops with a K-Pak treatment and went to bed. The following morning, I followed the advice of choosing a color that was quite a bit lighter than what I'd normally use, and selected a champagne blonde (!) - long story short, my hair color turned out absolutely perfect!!! It is now a warm golden brown with golden highlights - perfect for summer. The crown and ends are the same depth, and there is no color build up anymore, which was my goal. The processing smell is sulfur-like, reminds me of the 80s perms, but it's a small drawback compared to the cost effective, relatively gentle results you receive with this product.
Just be certain to use a good protein treatment when you are finished.

I tried Color Oops again last night. My hair had been orange at the roots, then gradually got darker until it was almost black at the ends. This time, I applied it all over my head starting 4" from my roots (because they didn't need it), left it on for 20 min, rinsed for 6 min, shampooed, rinsed for another 5, shampooed again, rinsed for another 10. Then I applied conditioner and left it on for 10 minutes and rinsed. I noticed that my roots were even brighter orange and the rest was exactly the same. I had no choice but to apply the Feria color I had purchased becasue I was NOT leaving the house with my hair looking the way it did! So, after spending more than $50 on 3 boxes of Color OOps and 2 boxes of Feria...my hair looks exactly the same, only more damaged. Terrific!

This product does work!!!!! I would leave it in a little less then the twenty min recommended. But it took the horrible color out and made it a golden blonde. If your hair is black it probably will turn it orageish so be prepared to dye it . but you can dye it the same day. Does stink though. but if you wash it and condition it the smell fades. Over all greatly satisfied

I'm a little torn on how I feel about this product. On one hand it did take some of my dye out, on the other my ends are still orangey and darker than my roots.
I paid $9 and some change for this at Walmart, and I got 2 boxes since I have long hair. One box came with plastic gloves, the other box came with a plastic cap to put over your hair. Weird. I used my own hair dying bottle to apply this, and there was enough product (w/2 boxes together) to fill the 10 oz. bottle pretty much to the top. It looked like I would have a lot left over, but I used all of it and I'm glad I did 2. Like the other reviews state, this stuff STINKS. A lot. It smells like sulphur + burning rubber + farts. It's also pretty runny, so it's a little difficult to apply w/out getting it everywhere. I rinsed for about 30 minutes then conditioned as usual. I highly recommend having a radio on while you're rinsing, half an hour seems like forever if you're waiting! I shampooed about every 2 songs for a total of 4x.
The results: My hair doesn't seem damaged, although it feels a little more dry than before I did this, and it is overall lighter. I have sandy light brown hair naturally, and I'd been dying it an auburn color. I got tired of how the auburn fades to a grody orange, so I decided to go back to my natural color. My ends are still a lot different than my roots so I might do another round of Color Oops to see if it removes any more color, although I'm not cherishing the idea! I think this might work better on freshly dyed hair, but it didn't wreck my hair and it did work a little so I'm giving it a 3.

Definately works. I put a color on to bleached hair that turned greenish on me. I ran to Walmart where this cost $6 or so and it took all of the color off quickly.

I used this a few times to remove color buildup from my hair, but beware--when you re-color it will turn out very dark and ashy, which makes choosing a new color difficult! Also, there's a very high chance that you never washed ALL of it out--even if you think you did. So even if you don't re-color your hair might turn out dark over the next few days.

OMG this stuff may have cured me of my hair coloring addiction lol. I had been dying my hair all sorts of colors for the past 2 years and was never satisfied. The past 3 months or so I had been dying my hair different shades of demi permanent red. I got sick of it and realized it didn't flatter my skin tone that well, so I got 2 boxes of Color Oops but didn't expect anything fantastic(I had used color removers before with blah results). At first I was somewhat annoyed when washing it out in the shower because it turned orangey blonde with yellow thick streaks in random areas. I was like great, I'm going to have to dye over it forever until my hair grows out... BUT THEN, I got out of the shower after rinsing for 20 or 30 minutes and it was a more normal shade of blonde!! And then Iput a little Fanciful Silver Lining rinse in it and blow dryed. Wow!!! My hair is back to something very close to my natural color!! And I barely put any of the Fanciful rinse in it. My hair looks healthier than before I used the Color Oops somehow. It does feel a little dry though, but I am soo happy with this color. I took off one star though because it did lighten all of my roots, which I would've preferred to stay dark. But they blend in nicely.

This stuff blew my mind. This significantly lightened my black hair without half the damage bleach did. After I used this my hair was a deep (mostly) natural looking red from black. There was hardly any brassiness which impressed me and my hair didn't feel like straw.
I'm naturally strawberry blonde but I've dyed my hair so many different colours. It didn't phase me to go from black to silver when my hair was short but I've worked hard to grow it out so I didn't want to do any extreme damage. I've been dying it black for about 2 years now.
I purchased two boxes because I have thick hair that goes past my shoulder blades, but I actually only ended up using one.
My recs:
-If you have wavy or curly hair like I do, I find if I straighten the day before makes it easier to distribute product
-This stuff SMELLS. I had to throw out a shirt and tshirt because I couldn't get the smell out. Beware
-I wish I used this twice before redying my hair. I think it would have helped because I'm not as light as I wanted
-I use the k-pak system regularly but I used it a few extra times after this which also helped
-If you're dying your hair after, purchase a MUCH lighter colour. I chose a light/med brown about 2 shades lighter than what I wanted but I expected it to turn dark. My hair went about 4 shades darker than the dye should have been, which I read can happen. That was my only bummer about this.
I would rebuy, it was $17.99 which is expensive especially if you need two boxes but well worth it!

I had great expectations from this product, reading all the 'great' reviews, so I thought i'd give it a try. My hair was previously bleached and i had dark brown hair dye over it, i wanted to use color oops to get it to a lighter shade so a red hair dye would show. After using it and drying my hair it seemed to work a little bit. But the next time I showered my hair went back to its original look.. dark all over again. My friend had the EXACT same problem, but she had even lighter hair than me!

I don't recommend this product. And it keeps this awful stench in your hair.
