I purchased their product and it left my hair super brassy and dry (with kpak, blonde toning shampoo etc). The sprayer broke after the 3rd or 4th use. I left an honest review and then got harassed multiple times about 'content integrity'. I provided multiple screen shots of my order and receipts, and even a picture of the product in person. This company is obviously trying to manipulate their reviews to get more sales. Dishonest and poor integrity.
