Be careful of the purple on your scalp [SEP] The only thing I will say is that it immediately took out the brassy tone in my hair and has a nice smell.<br /><br />Cons:<br />It left my scalp purple. I am not kidding when I say that I rinsed my hair 3 separate times and still found my hair/scalp purple. I don't have a mirror in my shower so I just kept rinsing out leaning over the tub. Finally after the third time, I said forget this and got back in the shower and washed my hair with my regular shampoo and conditioner. I still fee like there is a tiny bit in areas and my whiter blonde has a little purple tint. It was also very dry feeling after the three rinses. My hair felt like straw.<br />I am not sure if the scalp dying was because I used a shampoo brush and didn't have it immediately rinsed  out as I was putting on a face mask. I had accidentally went to put in the conditioner and realized after I put it on the top of my scalp that it was the shampoo and waited till my face mask was done drying a few minutes later to rinse out.<br />It really was drying even after I used my regular sulfate-free shampoo and conditioner and put in my super moisturizing leave-in conditioner. I might try it again if I have a color that turns out horribly and I need to tone it down. I was just surprised it how much it toned it down and my darker blonde now looks too dark/dull, unless it is still got some purple in it.<br />So if you use it, I probably would not use a shampoo brush and I would not leave it in at all. Not even the conditioner which says to leave in a few minutes.
