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 smellcons it left my scalp purple i am not kidding when i say that i rinsed my hair separate times and still found my hair scalp purple i do not 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 strawi am not sure if the scalp dying was because i used a shampoo brush and did not 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 outit 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 itso 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
