Hi-

I have brown hair with carmel highlites.  I only use shampoos and conditioners without the harsh sulfates and parabens, etc.  Even with using these expensive products, my highlites still turn brassy.  I can't figure out why this always happens.  I have been researching online for something and saw this product.  I have read very mixed reviews so far.  I want to try it  but don't want to make the color worse but I really want to tone down the highlites that I currently have.  The hair that is highlited also got very weak and split so I wanted to ensure that this product wouldn't do more damage.  Any thoughts???
