Reflections style innovation metallic touch hair dye is nonsense

Never, I repeat never but this products. I bought mine at dischem. My hair was light blond and I app**** the products for Atleast 30 mins. There was no change. I left it on for another 30 mins. While I check how it's changing. Guess what half of my hair is blackon top and brown on the roots and the sides where my hair is short it's dark brown. How's that even possible. I'm mean this product is expensive. Noo man!
