Great for getting any artificial colors that are hard to get out of Hair especially Red has a bad smell but works great and corrections for at home but still, I will consult with a professional first before using it 

This product is amazing! I put semi permanent red dye over my blonde ends and thought it had faded completely until I tried to bleach my hair again to go blonde. The color started lifting pink and I knew if I continued my whole head would be pink. I used color oops after bleaching a few strands already and it stripped it back to its blonde/gold tones and I’m so thankful. Will definitely be buying this product again.

Smells extremely bad but it made the black hair dye on my hair slip off! Works so well with removing hair and it did not take that long to start noticing
