A little over two months back, I used l’Oréal Colorista Washout “temporary” hair dye in the colour turquoise. My hair turned green.
Even though I really liked the colour, I didn’t actually want green hair forever. I trusted that the dye would fully wash out, as my hair is dark and has never been bleached or chemically treated. I documented the entire fading process of the colour, for the 15 washes that it was supposed to take for the dye to disappear, according to the packaging. After about 10 washes, when I washed my hair, the water was clear every time so I could tell no colour was coming out any more. I was left with pretty bright green staining on the lightest, driest parts of my ends, and a faint cool wash over my entire hair.
