Query: Excellent product!

I'd gotten highlights, and when I do, my hair feels like straw for a while afterwards. A couple days later, I picked this up and tried it. I could not believe the difference - my hair felt silkier than it had even before my highlights! The thing is, I've spent a small fortune on very pricey products that promise the same results and none have worked nearly as well as this product has, at a fraction of the price. This will definitely be a staple in my house.
