I just finished drying my hair after washing out Color Oops Extra Strength and i'm amazed! I've been dying my hair black for at least the past 5 years and I was finally sick of it! I didn't want to bleach my hair or do a bleach cocktail so I decided to try Color Oops because we finall got it in Canada. I left it in a little longer then 20 minutes(an hr, oops!), then washed it out in the shower for about 25 minutes, going back and forth between my neutrogena clarifying shampoo & a head & shoulders shampoo and then left conditioner in my hair for another 10 minutes. My hair is back to my natural brown colour, and it's still soft and healthy looking! I'm amazed!! My ends are still a littler darker so i'll probably use another box on them but Color Oops did such a good job! I'd reccomend it to anyone wanting to go lighter or get rid of black!
