If you’re thinking of taking the plunge and reaching for the blue black hair dye you’ve come to the right place. This is our definitive guide to blue black hair; how to get it right, how to make it pop and how to inject some edgy attitude into your style.

This color combination can make for a really sleek, chic look, but it can also go over the top very quickly. You might be opting for a tonal treatment, funking things up with some vivid blue highlights, or simply going for it with an all over color; either way, to ensure you get great results it’s important to select a tone that suits you.

We’re going to go over the options and techniques available so you can select the exact style that you’re looking for.

Black Blue Hair

Are you aiming for dark and sultry, but with a cool edge? If so, then this is the look for you! Subtle and chic, this hair color will take you from the office to the party and have you looking totally fab for both occasions. It transforms in different lighting, and the deep dark color leaves your hair with great depth and shine. To achieve this look, search for a dark blue black color that will give a high gloss. We also recommend treating your hair prior to coloring so it’s super smooth and ready to rock the new shade!

Blue Highlights

Want to inject some color? Blue highlights are the way to do it! We recommend pairing them with a deep blue black hair color as the base, so they really pop. Or alternatively, add the highlights to your natural color to simply rejuvenate your look. These are often great for a bit of fun as the brightness will fade after a few washes, but they also pack a real punch and make a real statement. These colored blue highlights work particularly well in layered hair, adding texture, interest and fullness to the style.

The All Over Look

If you like to make a statement with your hair, this is the one for you! An all over blue black hair dye will really make people do a double take and say ‘Wow’. Play around with colors and see what works for your skin tone and style. Fairer skin often works better using more of a purple blue, whereas darker, more olive complexions can take a deep cooler blue. This all-over color works best on short, cropped styles for a really vivid color pop to lift your look.
