Color Oops Extra Strength Hair Color Remover, Bleach-Free Dye Corrector

I have used this product several times in the last few years. It works, but you do need to leave it on a lot longer than 20 minutes if you are looking to lift any good amount of color. I left in on for 1 hour and used a blow dryer to activate it twice in that hour. When I have used it in the summer, sitting outside in the sun helps, too. I have had to keep it in for almost 2 hours before to achieve the lighter color that I needed. I had several colors of dark brown in my hair this time and I needed to lighten it to start all over with an even medium brown color. This did the trick. 1st pic is my starting color (white shirt) 2nd/3rd pic is the color after 1 hour of Oops. 4th picture is after dying again the same day (with dog). I will say it does dry your hair out, but after washing the Oops out, I always use a powerful conditioner (like what comes with box hair dye) to help put moisture back in. My hair is always healthy and soft afterwards if I condition it well.
