What is the difference between semi and demi-permanent hair color?

Does Demi-permanent cover GREY?

“Demi-permanent colors don’t cover the gray so much as they color it, making gray hairs blend in more with the overall color and look almost like a highlight,” explains Redken Artist Jason Gribbin.

Is permanent or demi-permanent better?

Creating highlights with demi-permanent color is often considered the lower-maintenance option because it can require less-frequent trips to the salon. Because the color fades more quickly than permanent color, your hair’s new growth will typically blend more easily and naturally with the faded demi-permanent color.
