I've been dying my roots which have a few flecks of grey, using semi permanent nice and easy. It doesn't fully cover grey hairs but blends them nicely. My natural hair is 95% dark brown with 5% greys. The mid and ends of my hair have ombré / balayage highlights.
I want to refresh the highlights as they are grown quite low down now. It would mean highlighting over the some of the section I've been using semi-perm dye on. According to my hair stylist that's fine as I've not used permanent dye. However, unfortunately I inadvertently used "Demi-permanent" nice and easy last week. (Picked up the box by accident as it looked the same). I'm not sure what "demi" means. Will it mean I can't highlight over the hair now?
Thank you
