I'm going to do this, probably this Sunday. I see the one with brighter results on YouTube use three packet and boil the water in 2 cups of water and let it cool for five minutes and then apply, I'm not worry about it be damaging because regular dyes are what dry your hair out and damage it (unless you keep your moisture up) and I will condition after. Not sure if I will deep condition before and then rinse and apply it and cowash after or just deep condition after
