37 Coolest Blue Black Hair Shades of 2018

For blue back hair, a dark black hue with a hint of blue is not only mysterious but very flattering. It’s a great way to show your daring side with every turn of your head catching the light and exposing your bluish hue! There are plenty of combinations of blue colors from lighter royal blue to navy or midnight blue to fuse with black hair color to flatter any skin tone. Lighter shades go well with dark and fair skin and darker ones compliment light and pale skin tones. Check out these exquisitely different ways to showcase anywhere from bold to soft blue black hair.

Blue Black Bob

This natural black hair color goes great with subtle midnight blue highlights. The short bob has great reflective beauty as the shades have a slight twist in hues more noticeable with movement. If you have natural black hair color, adding highlights can offering some flattering but not extreme changes.

Perfect Black Blue Ombre

Going from black to a lighter hair color for an ombre can be hard to to achieve so many people chose darker shades for a smaller transition. This icy blue is opulent with the black color from the top.

Black Medium Length Blunt Cut

If you are searching for black blue color with darker tones this is definitely the ideal look. The midnight blue can be seen as the light hits certain angles of the medium layers.

Bob With Blue Highlights

This short bob hairstyle combines the natural black root color with some blue hair dye and foiling to create panels of color. Adding the color to the bangs is a great touch as well.

Black Cobalt Hair Shoulder Length

Q&A with style creator, Nikki
Hair Colorist & Hair Artist in West Palm Beach, FL


How would you describe this look?

It’s definitely a dimensional cobalt hue. If you look at the individual locks of hair you can definitely see the different tones of depth in between.

What I love about it is that it’s definitely the perfect tone without any traces of green. Which happens when trying to achieve this tone if you don’t get it to the proper canvas. This will fade to a beautiful pastel tone over time.

Any advice for someone considering it?

Blue is a long-lasting color and tends to be on the stubborn side even though this is a direct dye. You definitely want to use a professional sulfate free shampoo or a cleansing conditioner with cool to cold water to preserve any direct dyes, limit sun exposure/salt water/pool water.

This color isn’t for someone who would want it to rinse out in a few weeks. I would stick with purples and pinks instead!

Fabulous Long, Thick Black Hair

Q&A with style creator, Erin Holm
Colour Specialist & Stylist @ The Collective Hair Studio in Scottsdale, AZ


How would you describe this look?

This is one of my favorite blue tones!

I went in with a matte black base color for the root shade as well as alternating it, with our pre-lightened pieces using a balayage technique. Pre-lightening pieces just off the root to ensure movement and dimension.

It has a very smokey denim hue indoors, where it can still be business casual! This same look outside has an extreme change in intensity! Going from cool tones to bright and strong deep tones.

Any advice for someone considering it?

This midnight blue hair color is very fun and versatile. It does fade within 3-4 weeks. You can rock the teal and mint tones, it fades too. To keep this strong deep tone, refresh it every 4 weeks.

For the pre-lightened procedure, use cool water and moisturizer to keep the cuticle sealed and to ensure the longevity of color.

When it comes to skin complexion, the tone of blue can be changed. I recommend, emerald or teal undertone for pale complexion and smokey cooler shades or a purple/violet undertone for warmer/darker complexion.

There are so many options, especially when you’re trying to spice things up!

Natural Black with Blunt Bangs & Textured Ends

Q&A with style creator, Caitlin Helle
Stylist @ Smoke + Mirrors in Baltimore, MD


How would you describe this look?

This a blue-black bob with blunt bangs and textured ends that provides a smokey effect.

My favorite thing about this look is the mix of severity and subtlety. The jet black color and blunt bangs make it more severe, but the textured ends and subtle blueish color take a little bit of the edge off.

Any advice for someone considering it?

Like any fashion color, blue black color requires a lot of maintenance. It is deceiving because it’s so much darker than the pastels and vivid colors you see all over Instagram, but it does still require lightening the hair. This client happened to already have some old highlights that were able to just be toned without any additional lifting.

Anyone considering this look should be aware that it requires regular appointments for touch ups and treatments (especially if their hair is already fragile or over processed), as well as using products at home to help maintain the color and health of their hair.

I send all of my fashion color clients home with a custom mixed color conditioner to help maintain their color. I also love Overtone conditioner for color maintenance.

Black Swan

Q&A with style creator, Erika Lupercio
Hairstylist / Assistant Salon Director @ J & Frank Professional Hairstylists in Yuma, AZ


How would you describe this look?

I called this look “Black Swan”. This look is can be referred to as a “shy vivid” because it’s perfect for people who want to enjoy an unnatural shade while still being workplace appropriate.

My favorite thing about this look is how it changes in different settings. It looks like a deep black indoors but in the sunlight, it has the slightest tone of blue.

Any advice for someone considering it?

To achieve this type of look, the hair needs to be previously lightened for the color to adhere to the hair properly, as well as for the pigment to show. To maintain the color, I created an Olaplex color bomb for this client that can be used every wash to redeposit the color every time.

Onyx Black

Master Stylist @ Vintage Hair Loft in Anderson, SC


How would you describe this look?

This look would be an onyx black. My favorite thing about this look is that it’s versatile. She can be edgy and professional at the same time while having subtle hints of navy.

Any advice for someone considering it?

Invest in a color-safe and sulfate-free shampoo. This will keep that color vibrant.

This is truly a great color for just about any skin tone, whether warm or cool porcelain. With the onyx, it allows any black to radiate.

Subdued Vibrancy Two Tone Color

Q&A with style creator, Sonny Quisol
Stylist @ Union Salon South in Pasadena, CA


How would you describe this look?

This look has a subdued vibrancy that offers versatility. Indoors it can appear almost black, but outdoors in natural light, it illuminates with beautiful tones of blue.

I love this look because it can be professional and fun, all while giving a kick of personality.

Any advice for someone considering it?

This look is definitely for a person who currently has or has had black hair and enjoys being “dark”. It’s certainly for someone who wants to add life and personality to their hair. It is considered a fashion color, which means it is a direct dye and requires maintenance.

Depending on the client’s hair type, texture, previous chemical history, at-home care, and lifestyle, this color may fade rapidly. Fashion colors typically last anywhere from four to 20 shampoos depending on depth, tone, the integrity of the hair, and of course the temperature of water and the quality of shampoo. Hair should be washed in cool water with a professional, sulfate-free shampoo.

It is important that a client comes back every six to eight weeks for a color refresher to deposit those tones back into the hair. This look has a mild amount of maintenance, but with proper knowledge, regular salon visits, and a passionate stylist, you will consistently have fun and beautiful hair.

Jet Black Long Curled Hair

Q&A with style creator, Laoreta Ismaili
Stylist & Make-up Artist @ Dawns Pizzazz in Danbury, CT


How would you describe this look?

I love the shine, vibrancy, and contrast in this beautiful color! I get excited when a guest wants to be fashion forward and adventurous.

Any advice for someone considering it?

She will have to re-glaze every five to six weeks to maintain the vibrancy and use color-protecting products to maintain the integrity of the hair and color.

This look is fun, flirty, and vibrant. The type of person who can wear this look is someone who is creative and edgy with a strong personality. It’s perfect for the person who likes to stand out from the crowd and be that “wow” girl!

Sleek Straight Black Hair

Strong & Fierce hairstyleInstagram @hairbykirst

Q&A with style creator, Kirsty Richey
Salon Owner / Hairdresser / Makeup Artist @ Chelleon for Hair and Beauty in Woodend, VIC


How would you describe this look?

This look has attitude, and it’s strong and fierce!

I love that it’s not just a plain old black color. It has edge and personality to it! The high shine and quality color are what make it perfect.

Any advice for someone considering it?

Any client wanting this color needs to know the commitment blue black requires. It is one of the deepest colors you can go to, and to remove it is very difficult.

For those dark-featured clients, it’s so easy to maintain. Pair it with an edgy blunt cut for a professional look that speaks volumes. With natural black hair, adding some shine spray will definitely improve the overall look.

Black Midnight Blue Color

Q&A with style creator, Koren Cartwright
Hair Colorist @ Hair by Koren at The Hair Lounge in Lincoln, NE


How would you describe this look?

I am OBSESSED with the depth and dimension that this look gives! It’s dark and bright at the same time and invites conversation. I would describe it like the waves of a storm at sea. Fierce!

My favorite thing about this color is how beautifully the demi-permanent @guy_tang #mydentity color reflects the light. It’s so vibrant. I used the shades 1MB (midnight blue) and 3MB and I added some aqua booster to the color on the ends to make them pop. I also included Olaplex in her lightening and color service to ensure her hair remained healthy and the color would last as long as possible!

Any advice for someone considering it?

Even though we did blue black on her hair, in order to get the blue to show up so well we still had to pre-lighten/bleach it out to a light blonde first.

Colors like this are high maintenance and require regular salon visits. If you’re considering a look like this, I recommend reaching out to your stylist to talk about pricing and upkeep. Ask if it’s a color that would work with your hair type and lifestyle as well. If you can find a stylist with #mydentity color and Olaplex, that’s an extra bonus!

Rich & Classy Blue Black

Q&A with style creator, Kailee Slaunwhite
Master Stylist / Colorist @ Lift Salon and Spa in Lakeside, Nova Scotia


How would you describe this look?

This look is so rich and classy and will turn any head. Blue (no matter what tone) has a very cold background, so black is its best friend. Black is rich, inviting, and will complement just about any eye color. If you suffer from rosacea or feel as if your skin pulls warmth (reddish), you may not think it, but black against your skin will cool it off and will leave you looking foxy!

Any advice for someone considering it?

First things first, the hair must be healthy enough to handle a little pre-lightener. Hair color (no matter what color line from across the world) CANNOT perform miracles. If your hair is brittle or broken, start by using salon haircare treatments. Products not bought at a salon or beauty supply store are NOT professional products.

Upkeep is VERY important with any color. In today’s world, there are so many pigmented shampoos so there is no excuse for your hair color to fade quickly. For this client, I recommended Blacklight blue shampoo, Olaplex No.3, and Red E To Go. She also struggles with frizz, so we used Bedhead After Party for a more sleek style.

This shampoo is marketed for blondes to counteract any yellow tones, but don’t kid yourself, this heavily pigmented shampoo will keep depth in any hair color.

I balayaged the blueish tone against the black so she would have a blended but contrasted look. She is 75% grey, so the balayage is perfect considering in four to six weeks she will only need he regrowth colored.

As much as this color may seem daring/scary/outthere/in your face/only for the young, it is actually a very sophisticated and bold look that is achievable by any HEALTHY hair type or texture. Remember, it’s not the color you wear, it’s how you wear it. All you need is confidence!

Blue Black Dimension

Q&A with style creator, Kayla Krommer
Licensed Professional Cosmetologist @ Salon LA in Cincinnati, OH


How would you describe this look?

This look is one of my favorite looks/colors to create as a hairstylist. This color is perfect for someone that wants a very modern and classic look, but still wants a little vibrancy, dimension, and an extra pop of color.

My favorite thing about this creation is that it is still acceptable for a professional work environment but in certain lights, especially the sun, will give you a bunch hues within your elegant, black colored hair.

Any advice for someone considering it?

I personally feel that anyone can try this color, no matter what face shape or skin tone you have. Although changing your hair color to black can be intimidating, it may be rewarding in the end! Hair color can always be changed, so if you are thinking about trying this, I would say go for it!

This is an easy color to maintain and even apply, which is great when you don’t have a lot of free time to spend at the salon. I definitely recommend a color-protecting shampoo and conditioner (I use all Paul Mitchell products) to keep the hair color long lasting, shiny, and vibrant.

To create this look, I used Paul Mitchell XG: equal parts 4AA and blue intensifier with 10 vol for the most deposit of color to the hair.

Bold Blue Black Bob

Bold Bob hairstyleInstagram @hairmagicmace

Q&A with style creator, Macie Sanko
Stylist @ Bzar Salon in Lawrence, KS


How would you describe this look and what is your favorite thing about it?

I would describe this look as a bold, blue black bob. My favorite thing about it is the combination of non-traditional or “fashion color” blue with an ashy indigo black base color. Many blue black hair colors are more of an all over dark color with a hint of navy. I love that this client isn’t afraid of being bold!

What products do you recommend to create and maintain this look?

To maintain this look, I recommend a color-safe, paraben-free and sulfate-free shampoo. My favorites are by MoroccanOil and Kevin.Murphy! I would recommend purchasing a color-tinted conditioner to maintain the brightness of the blue highlights at home. My favorite brand is Overtone for at-home color maintenance.

What type of client would you recommend this look for?

The perfect client for this hairstyle is someone who is either comfortable with a little more at home care to maintain the color or someone who doesn’t mind coming in frequently for touch-ups (about every five weeks). Non-traditional fashion colors are not low maintenance due to fast fading.

This look is great for people who have a warm skin tone and want to counteract redness in their face. These bright colors fade quicker with the use of heat, so someone who has a low maintenance style routine without a lot of flat ironing or curling is best!

Jet Black Bob

The exotic shine of ocean over jet black hair paired with a simple bob haircut makes a bold statement!

Best Skin Tone and Hair Type:

Soft pale skin with little pink undertones looks great in this hue. Hair that is straight in texture and medium to thick in density wear this classic bob best.

Tip:

Remember to keep the hue bright and longer by using sulfate-free shampoo and conditioner. Try Pravana’s Pure Light Shampoo. It’s blueish/violet base will support your color with every wash.

Black and Indigo Stripes

A slight indigo highlight placed to peak out of your black or brunette hair will draw attention in any crowd!

Best Skin Tone and Hair Type:

Medium to light skin tones that look great in blues and teals wear this color best. For this cute asymmetrical pixie,  hair that is medium to fine and straight to wavy creates a perfect style!

Tip:

When styling your hair, you can choose to have your indigo stripes be bolder by simply changing your part! Try splitting hair in the middle of your indigo highlights and sweeping it off to the other side for a night out on the town. This would also work well with black hair as well.

Long and Lovely Curls

Adding a slightly different hue to your hair creates a nice shine indoors, and gives some fun and interest when stepping out into the sun.

Best Skin Tone and Hair Type:

For this darker shade, a medium complexion suits it best. Hair that is medium to thick and wavy to straight will hold this blunt fringe and soft wave style best.

Tip:

When creating this soft wave in your hair, try using a curling wand instead of a traditional iron.  Wrap hair around the barrel starting halfway down the section. Hold ends close, but not directly on iron. Let each wave cool before running fingers through or using a paddle brush to comb out.

Short and Sweet Crop

A sassy haircut paired with a soft, blue black hair color looks fun and professional.

Best Skin Tone and Hair Type:

Medium to light skin tones with naturally darker hair look stunning in this blue black color. Straight, medium to thick hair creates a perfect canvas for this textured short cut.

Tip:

Keep your shine amped up! Rinse hair with cool water to close the cuticle layer and add a shine enhancing oil to your routine.  Try Kevin Murphy Shimmer Shine. It is super lightweight and has small bits of mica to reflect light.

Perfect Party Hair

The messy sexy style perfected! This loosely pulled up look with the perfect amount of bits hanging down paired with jet blue black hair color will have everyone noticing you when you walk in the room.

Best Skin Tone and Hair Type:

Fair skin tones that look great in deep purples wear this blue black hair color perfectly. Hair that is straight (or dried straight) will twist up into this sexy updo effortlessly.

Tip:

After drying hair, pull hair back into a loose ponytail. Pull out bits to frame your face, then wrap the rest of the hair around ponytail base and secure with pins. Make sure it’s secure, but it doesn’t look perfect. Finish off with a shine-infused hairspray.

Black Turquoise Vixen

Fine turquoise highlights through this jet black base color give a brighter effect and increase the va va voom factor!

Best Skin Tone and Hair Type:

Fair to medium skin tones that look stunning in greys, teals and greyish blues have this color covered! Thick, straight to wavy hair helps create a full look to show off this amazing color.

Tip:

When going for highlights, remember that your colorist will first have to lighten your strands to a pale blonde before overlaying with turquoise shades. Ask for recommendations to see if your dark hair can handle the process before jumping in!

Blue Black Formal Hairstyle

Mountains of texture and darker hues make a bold statement for any daring lady! The perfect amount of height, curl and varying hues make this look to “dye” for.

Best Skin Tone and Hair Type:

Light to medium skin tones work well with this beautiful blue black shade. Thick, wavy to curly hair creates a base for this look to reach new heights.

Tip:

To achieve massive height, start with a volumizing foam through your crown and top of the head. Blow dry hair upside down and direct it in the opposite direction of where your finished style will be. Flip head over and separate into small sections to create backcombing. You can use a brush or comb for this step. Smooth hair over backcombing and spray with a hard hold hairspray to finish the look.

Short Pixie

Sometimes the old rule of less is more still holds true. A slight blue hue to jet black hair compliments this cropped pixie stunningly.

Best Skin Tone and Hair Type:

Soft pale skin tones with lighter eyes make this color pop! Hair that is straight and medium to thick make styling this pixie cut a breeze.

Tip:

Want a different look? Try using a texture cream, such as Pravana’s Twist, to push strands up into a faux hawk or spiky look!

Natural Black with a Pinch of Indigo

Give naturally black hair a soft glow of indigo. Indoors it looks shiny and healthy, but once you step out into the sun, it shows your wild side!

Best Skin Tone and Hair Type:

Medium skin tones that look great in deep shades of grey, violet, and indigo are a perfect match for this color. Hair that is naturally curly and medium to thick wears this look best.

Tip:

Keeping your curls and color hydrated is very important. Using a weekly at-home conditioning treatment will give you shine, moisture and manageability. Try Pravana’s Nevo 60 Sec Deep Treat. In only one minute, your locks will be nourished and happy!

Straight and Sleek

One of the best ways to show off shiny, blue toned color is to wear it straight and sleek. Walking into the wind also gives you a great blown away look (and keeps hair out of your lip gloss too!).

Best Skin Tone and Hair Type:

Light to medium skin tones look best in this hue, while hair that is naturally straight and medium to thick achieves this look effortlessly.

Tip:

If your hair needs a little help, go ahead and use a flat iron. Just remember to turn the heat down (nothing over 390 degrees) and use a heat protecting spray. Small sections and slow, even tension is best for your hair.

Bright Ocean Teal

Create a splash with bold panels of an ocean teal through blue black hair this season. This hue is eye-catching and daring, but not for the faint of heart or hair!

Best Skin Tone and Hair Type:

Pale skin tones with cool undertones carry this bold color well.  To achieve this asymmetrical cut, fine to medium strands that are naturally straight are cut to show off a delicate face.

Tip:

Bright colors are the hardest to maintain. The more you can refrain from washing, the better! Ask your stylist for their recommendations on a dry shampoo to use on days you don’t wash. My favorites are Pravana’s Fresh for volume, or Kevin Murphy Fresh Hair for sleeker looks.

Blue black hair ranges from bold and bright, to soft and subtle. Pick your hue and get an appointment with your stylist now!  Remember though, it is a commitment that is not easily removed from your tresses.
