So, I'm pretty 'hippy' when it comes to all the products I use. Even on my hair. However, since going blonde I had to give up the whole co-wash routine because I needed to tone out the brassiness. I tried using Kevin Murphy's Blonde.Angel Treatment only and it was ok for taking out the brassy yellows and amazing for conditioning the hair, I even tried Davines Alchemist Silver Conditioner - which was a bit meh for me. BUT using this is combination with Fudge Clean Blonde Violet Conditioner WOW. I've got to say, yeah it completely cleans up the brassy issues. I have waist long blonde hair and lots of it so I require several pumps. Just focusting it at the roots and dragging the suds down is not enough to cut out the yellow so I need to add fresh pumps to the length. I leave it on for approx 4-5 mins with no purple tinting. So the 1000ml is very economical for me. The price can't be beat. The pump is really sturdy. I wish the design of the label and bottle were nicer and more minimalistic and modern but whatever. I can overlook that. Years of Kerastase, Aveda, and much pricier products and this killed all of them. IN LOVE.
