How to Get an Ultra Cool Blue-Black Hair Color How to Get an Ultra Cool Blue-Black Hair Color How to Get an Ultra Cool Blue-Black Hair Color

New season, new hair color. While summer might have you thinking that golden blonde and sun-kissed brunette shades are the only options for the warm weather, we’re here to put a much darker shade on your radar. First seen cascading past one of your favorite reality star’s shoulders, this deep shade features a cool blue-black color that will add an air of mystery to your summer beauty look. The best part? It will easily transition into autumn, so long as you take the steps to maintain the bold color.


Since an ultra-cool blue-black hair color features a specific color combination to create the ultimate eye-catching shade, you may want to leave this look up to the professionals. A trained colorist will be able to bleach and brush on color to get you the dye job you desire. If you’re starting with a very dark base, it may even take multiple sessions to get the look you want since the bluish tint may not easily adhere to your already dark color. That’s why it’s a good idea to set up a consultation with your colorist before jumping into the dyeing process—he or she will be able to give you an estimate of how long it’ll take for you to achieve your blue-back hue.

Now, since we know some of you will want to try your hand at this all on your own, there are ways to do that, too. Namely, you can stock up on the L’Oréal Paris Superior Preference Hair Color in Deep Blue Black. The luxurious permanent hair color will deliver super shiny strands from root to tip. Best of all, it can be used on all hair colors to create the ultimate blue-black hair color in the comfort of your own home.


Any time you color your mane with permanent hair dye, switching up your hair care routine is a necessity. Without tailoring your hair care routine, you’re looking at fast fade-out and dull lengths. Since that’s definitely not the look you’re going for, be sure to follow the steps below to help keep your blue-black hair looking and feeling its best.

1. Use a Color-Safe System of Shampoo and Conditioner

Say bye, bye to your regular shampoo and conditioner. Switch them out for a system specifically formulated for color-treated hair. Try the L’Oréal Paris EverPure Repair Defend Shampoo and L’Oréal Paris EverPure Repair Defend Conditioner. Make sure to shower in lukewarm water, as super-hot H2O can strip your strands of essential oils, leaving it feeling dry and looking dull.

2. Add a Hair Mask to Your Weekly Hair Care Routine

You may find that your color-treated hair needs a little extra conditioning from time to time. In that case, swap out your conditioner for a hair mask, like the L’Oréal Paris EverPure Remedy Balm, once or twice a week. Apply it after shampooing, and leave it on for 3-5 minutes, then rinse out.

3. Pump Up the Shine with Hair Spray

Part of what makes blue-black hair stand out from other hair color trends is the cool shimmer and shine, so go ahead and use a high-shine hair spray, like the L’Oréal Paris Elnett Precious Oil Satin Hairspray, to help style your strands. Spray it evenly through dry hair and scrunch for a slightly lived-in look, or use it as a last-step of any other hairstyles you’re working with.

4. Book Touch-Ups at The Salon

Even with permanent hair color you’re looking at root growth every eight weeks or so. Once you start to notice a sliver of roots, determine if you like the look with your ultra-dark hair color and if you prefer a fully colored ‘do, make an appointment for a touch-up — and, while you’re at it, ask for a gloss for an extra pop of shine.

5. Weave a Braid or Two

Try a braided look to draw attention to your blue-black hair color. Whether you opt for fishtail, French, waterfall, or Dutch, you’re sure to look fab.

6. Create Effortless Waves

Adding shape and body is a good look on every color. While you can tease your hair at the crown and follow with a curling wand to make waves, we especially love how effortless (and non-damaging) creating waves with the L’Oréal Paris Advanced Hairstyle AIR DRY IT Wave Swept Spray can be. Simply spritz it into damp hair, scrunch, and be on your way.
