Blue Hair: 30 Blue Hair Color Ideas

Depending on the color you’re beginning with and your desired shade of blue, the coloring process can be everything from fairly simple to an involved, multi-step affair. Very dark blues that look almost black can be applied over any hair color, and you can find dyes in a wide variety of price ranges that will get the job done. Like pure black dye, these ultra-dark blues will stick around for the long haul, and you’ll probably need to strip the color if you decide you want to go light again. Lighter blues in pastel or bright shades should be applied to pre-lightened hair to get vibrant results. If you’re after a true blue color, be sure to get your hair light enough beforehand. Using blue dye over orangey hair can turn your strands green instead of a pure blue shade.
