Dark blue hair is a color that blends a deep blue tone with naturally dark hair. Achieving a shade of dark blue involves mixing deeper shades of green and violet and applying them to dark hair.

Having dark blue hair makes a striking fashion statement. It has gained popularity among celebrities and influencers like Billie Eilish.

Be aware that a professional colorist is recommended for applying certain variations of dark blue hair dyes.

When figuring out how to attain darker blue hair, remember that when dyeing it this dark blue, it’s essential to pre-lighten your strands first if you desire a vibrant outcome.

A dark blue tint enhances every complexion with its customizable shades, and showcasing this dark denim hair color with textures allows you to highlight the natural dimensions and highlights it has.
