would not recommend [SEP] i have used manic panic amplified for years but decided to try this because manic panic has not been lasting as long as it used to i had high hopes for this but was very disappointed i left the dye in for at least an hour before rinsing with cool water but the color was not nearly as vibrant as i expected it to be additionally my scalp and face got very itchy while i had the dye in my hair being the fast learner that i am i decided to try the dye again the next day the itching on my face and scalp started much faster this time and my neck also got very itchy still i assumed it was a coincidence because who is actually allergic to hair dye despite the warnings to do a strand test so a few weeks later i tried it again and the itching started even faster that time i decided i was not going to use this on my hair again but had the bright idea to squeeze some onto the back of my hand when i was applying it to my nieces hair within about minutes my hand began to itch and burn i do not have sensitive skin and have never had an issue with dyes before so i am not sure what is in sparks that is not in manic panic
