Kristen - it is about $25 a bottle (almost $50 for shampoo and conditioner) but you use only half the amount you would a normal shampoo and conditioner and you won't need to use a seperate toner anymore.

I guarantee its worth it. Peroxide can really dry out and damage hair so its worth investing in a good shampoo and conditioner to keep it healthy and manageable. I've tried other brands (such as RPR) but they just aren't as good!!
