Query: Didnt work

It did not discolor my blonde but....it didnt work. As a matter of fact I purchased two boxes and applied two different times. I followed directions to the T and the day I was the product out, both times, my hair went back into the kinky, wavy, fried blonde it had been originally. Wasted four days of my life with ugly oily hair matted down on my head for nothing
