I always use this product when on sale. Have always had great results. But this time while it was on I notice a purple hue to the dye. I was curious but waited and when I rinsed it out my hair had a purple tinge to it. Wow, checked the box again to make sure. Yes it was the one I bought. Was talking to my mother and she said her hair turned purple and saw my sister and she said you will never believe what happened. I got the box out of the trash can and she said that is the same one I bought at Shoppers near my house. How crazy is that. It been a week and the colour is fading. But skeptical on buying this brand.
