Icy silver cool tones with a quick shampoo

This is a product I've been dying to try and my hair dresser used this to tone my hair and I just had to have it. I've also heard amazing things from other who love having that icy cool silver blonde hair. For best results I'd leave on for 10 minutes as soon as you notice your hair getting brassy. Use this on top of your regular purple shampoo & conditioner. The price in comparison to its effectiveness was extremely surprising as well. Will be a staple in my hair care routine.
