LOVE THIS PRODUCT!! Dyed my hair the blackest of black and it look unnatural, i wanted my dark chestnut color back after a few weeks of it being horribly black i decided to try this because I had heard so much about it lately. I read the reviews, was skeptical, thought it would fry my hair, but i figured what the heck, so I went for it. $10 at Walgreen's. When I applied it stunk to high heaven!! Smelled up my whole house.Sorta like raw sewage or REALLY rotten eggs. My hair still smells after a week, only when it is wet though. ANYWAY, IT IS WORTH IT!! Took the permanent black pigment out, left very nice even chestnut color. No multicolored mess! I expected the ends of my hair to be darker than the top, but it wasn't. Unbelievably worth the money, and smell. I have shelled out a couple of hundred dollars at a salon when this happened before, that harsh stripping fried my hair. Not Color Oops though, it left it really soft, it is not a harsh treatment at all. Still looks shiny soft and healthy like before. I will use this product again if I have anymore hair mishaps.

I've used this product three or four times, and I'm always impressed with the results. My last endeavor (which was today) was to take out a bad dye job. I'd used L'Oreal Healthy Look in Light Reddish Brown, and I started hating the color. It was too dark, and the red looked extremely fake.

I left Color Oops Extra Strenght on my hair for 20 minutes, and it's lighter than it's been in a LONG time. I'd describe the color as light golden blonde, or extremely light strawberry.

If you use Color Oops, I recommend waiting a few days before you recolor, or to pick a shade that's 1 or 2 shades lighter than what you want. So if you want level 7 hair, go wth an 8 or 9. Color Oops does leave your hair fairly porous, and it sucks up color.

Ok I've been dying my hair solid black either jet black,natural black, blue black from the box and twice in a salon for I'd say a little over a year and am finally tired of it but nobody ever mentioned that you can't undo the black, or dye over it so I found out the hard way and tried to dye it a dark brown((i'm stupid, I know)) well waited a wk or 2 to let it rest before trying the extra strength color oops, bought 2 bottles, I let it sit for about 25-30 minutes bc I thoroughly distributed it through every strand to make sure there would be NO spots, rinsed it however many times, shampooed it, conditioned it all that good stuff and for longer than the time stated bc my hair so thick&long..even showered a lil while later so involved some more rinsing, welll I dried it and the roots were like WOW the crown was yellowy orange and the roots were orangey from me trying to dye it dark brown so the roots didn't have any black so i expected this and it didn't look as bad as you'd think and the rest of my hair did turn back a brown almost close to the natural color with a few black streaks here and there but it actually looked good, so I decided to sleep on it to decide if i even wanted to dye it again bc i liked the results and 2 let it rest aaaaaaaand woke up very next day with solid black hair again :( so I don't know what went wrong but I can say I'm pretty upset :( continued >>

I think this works about the same as L'Oreal's Color Corrector, but it does work. I tried a Medium Ash Brown on my normally mousy brown hair and it turned it nearly black (thanks, Excellence Creme To Go). This lightened the color but turned it a rather orange shade (I've come to expect this from color correctors, because it's pretty much impossible to actually remove the color from your hair). To balance out the dryness this can cause I shampooed a bunch and then used an Alberto V05 Hot Oil treatment between shampoos; it made my hair baby soft again.

It works(took my bright red dyed hair back to its bleached blonde base with only a little brassiness left at some stubborn spots.), and will save you a lot of money, (color-corrective services are not cheap, I know from lots and lots of experience). I wish it included a plastic cap, which the instructions recommend you use. (I used saran wrap, worked just fine.) Follow the instructions and be sure to shampoo like a dozen times because it smells AWFUL,like rotten eggs( I do recognize the smell as being the same as when i had black dye stripped from my hair at the salon). there's no sugar-coating it, and the smell is still lingering in my hair right now. Be sure and rinse for the required 15 min or more, and deep condition your hair. But it does work very well and is definitely worth the 13.99 i paid for it

If only I had known about this product years ago. I've spent hundreds (maybe even close to a thousand) of dollars in my life on corrective color - yes, corrective ONLY - because of too many botched dye jobs. I used Color Oops last night because my unnatural, inky looking Colorsilk Black HAD to go. I looked like a witch in pictures. Anyway, I had colored it months ago and have been itching to go back to a medium golden brown without shelling out $300 (gotta love NYC salon prices). I brought it home and prepared myself for a) a horrid stench and b) a ton of rinsing to get me to my result. This stuff does work. It's the ONLY product I've tried that has dramatically lifted my color at home. Is it bleach? No. Will it lighten naturally dark hair? No. It's meant to lift artificial (aka hair dye) pigments from the hair, and will leave you with the lightest color you were BEFORE you darkened it. For me, that was a light brown with blonde highlights. Unfortunately, that's not what I was left with when I rinsed. My hair was a medium copper auburn which, I actually didn't hate on my fair freckled complexion. But since I wasn't in the mood for the "oh my GOD your HAIR!" comments at work today, I had a standby hair dye on hand in case this happened. Thankfully, I took the advice on the box and went with a much lighter shade than I'd usually get because my newly stripped hair was very porous and would absorb a lot of color. I used Garnier Herbashine Light Natural Brown about 15 minutes after the Color Oops. My hair is now a pretty, medium/dark reddish brown which I know will fade a little more because Herbashine is not permanent. Long story short, Color Oops does work, but everyone's hair is different and I don't think there's a way to predict what color you'll be left with. Oh, and my bathroom and towel smell like rotten eggs. I'd use this again for sure - I think it's well worth the money, and gets the job done.

used this product and had to find a place to review it! I have naturally dark blonde with some gray (I color the roots regularly with a dishwater blonde color). I also have it highlighted a bright blonde. I normally like a beige blonde with some variation. My hair color was getting to be too solid blonde so I went to my hair dresser. He added low lights which I had asked for. He had just started using the new Loreal color Inoa and he was so excited about it. The first low lights were copper and even he didn't like them! He re-did the lowlights a dark ash color, dark. At the same time I asked him to add some more highlights since the original lowlights were way too dark in my bang area. I like lighter blonde around my face but the lowlights had really grabbed onto the bleached hair. The color came out awful and I had spend over $150.00. I really just went in to get my roots done! I spend over 5 hours in the salon waiting for these two color applications to work. I was so, so, so unhappy with the drab, dark, un-shiny hair I came out with. The lowlights literally sucked the shine out of my blonde. It was so upsetting. I considered going to a cheap salon and having more highlights put in to cut through the painted on looking dark drab streaks. Instead of doing this (which I didn't think could have been strategically placed on top of the lowlights) I went and bought this hair color remover. It was $13.00 and a pretty scary experiment! I didn't think much could look worse than when I left the salon. I saturated all of my hair and concentrated on the dark lowlights. I left it on as directed for 20 minutes and washed it twice and rinsed it for 15 minutes. That was a long time to rinse but they stress this in the directions. While it was processing it looked like it was turning a very slight brassy, orange tinged shade. I held my breath! Once I got out of the shower, after rinsing, my beautiful bright blonde was back! It didn't even mess up the color of my roots! The color is beautiful now, it's the best $13.00 I could have ever spent! While rinsing, your hair will feel majorly dry, like you washed it with a strong shampoo 100 times. I towel dried, and put a heavy deep conditioner on it with a plastic cap for about 30 minutes. I just dried my hair and it looks beautiful. I ran to the computer so I could help someone else! I wouldn't recommend you do this process twice because your hair would be like straw. For a dark blonde, with tons of bright blonde highlights who got a bad color job, this works perfect. Good luck!

This worked great on my unevenly colored hair!! I had a color mishap that resulted in blond/red roots, light brown mid-length, and dark brown ends. I was devastated and attempted to color over it with a medium brown, but that just made the unevenness worse. So, I decided to try Color Oops. It removed all the dye from my hair, taking it to a light bronzed brown color after just 13 minutes. Not only was my hair the perfect shade to recolor over,Color Oops also made my uneven hair color all the same tone, so when I recolored my hair, it came out nice and even. The damage was minimal, Color Oops just made my hair a little dry. I have vowed never to do at home color again, but if I go back on my word and should have another at home color mishap, I will definitely be purchasing Color Oops again!

I tried to dye my hair brown. I used to dye my hair monthy, but brown would always fade from my strawberry blonde hair. I dont know why, it just never held color very well. I thought to myself, i havent dyed my hair for a while so i bought natural instincts in nutmeg. yeah, it came out black. I bought prell which lightened it a little but still not enough, so I bought color oops. after fifteen minutes I noticed my hair was turning orange. I might have some red naturally in my hair, but not like that!!! I paniced and instantly called my hair dresser for corrective coloring. She has fixed my hair before so naturally, she was upset and told me to stop messing around with home hair coloring. and shes right, especially with a drastic color like brown for someone who has strawberry blonde, be careful. Of course it really held the color well this time! she told me the best thing i can do for now is condition so i let the conditioner set on my hair and i fell asleep. when I woke up and rised it out, it was back to my normal color. Dont ask me how, but atleast I dont need to pay for corrective coloring. She told me my roots turned orange because that is where most of the heat is on my head, so it chemically reacted. I gave this a 3 because it does lighten color, but dont expect it to bring you back to your natural color. Once its processed, its processed thats it. grow it out thats all I can tell you. For someone else, conditioning might not bring back the color and corrective coloring costs an arm and a leg. It also smells like rotten eggs. USE WITH CAUTION

I wrote a review for the regular strength version and added a glowing review on this product at the end. I actually used this about two years ago with terrible results. My hair was fried and the odor was unbearable. I ended up needing to do this process again today after a disaster with a home color-job two days ago (THE DAY BEFORE EASTER!!) and the store only had the extra strength but I was desperate so I purchased it anyways. The box said "new", so I hoped for the best. The smell was much more tolerable and it removed the green tint in my hair that I wanted to get rid of. My hair now looks bleached out, but I can live with this a lot better than GREEN hair! My hair also doesn't look worse for the wear, very soft considering what I put it through these last two days! The box says that the hair can be redyed the same day, but for now I'm not taking any more chances.
