This shampoo is very drying, even for a toning shampoo, and since it's also one of the most ineffective ones I've tried I see no reason to repurchase.
The only reason I'm saying I would buy this product again is because it was dirt cheap (I got it at Winners) for a huge bottle, and so far it has kept my blonde highlights from fading. However, I do not recommend it for dry hair because my hair feels almost like straw when I rinse it, and the only saving grace I have is that I use leave in conditioners and Morrocanoil, and a good deep conditioner. Overall, I would not pay full price for this, and I think a shampoo for color treated hair would be better than this silver shampoo for blonde hair.
