So....I have used Jhirmack purple shampoo for years now. It isn't as deep conditioning as Shimmer Lights or even as strong, but it's a few dollars cheaper. But yesterday I decided to myself," Why not go back to Shimmer Lights?" And so I did. The problem is, I forgot you cannot leave it on as long as Jhirmack shampoo. It is MUCH stronger. My result? PURPLE HAIR! And I mean Barney Purple ALL over! I have actually done this before, a few years ago. It was a nightmare. But this time, I decided to calmly look for a solution and not break into a panic!
I took a tiny bit (about 3 ounces) of bleach from a revlon hair frosting kit, and I mixed it with a lot of Samy moisturizing shampoo (you can find this at any CVS). I scrubbed this mixture into my purple hair and left it on for about an hour. When I washed it out, all the purple was gone and I was left with perfectly toned hair!
I will continue using Shimmer Lights once a month or so, when I feel like my hair is getting brassy, but I will NEVER again leave it on for more than 2 minutes!
