Made my hair look like straw!

I was so excited to use this product as I had heard that it really helps reduce and control frizz. I have fairly curly, processed hair that tends to get dry and appear frizzy so I decided to spend more than usual on this shampoo. After using it my hair looked terrible, I decided to try it a few more times to see if it changed but it even got worse and my hair ended up looking like straw. Sadly I am throwing it out, what a waste of money!
