36 Jet Black & Blue Black Hair Colour Ideas for Glossy, Bold Hair
—
Introduction
Jet black and blue black hair colour ideas never go out of style because they do two things at once: they look polished and classic, yet they carry a cool, modern edge. Jet black is the deepest, glossiest black you can wear, while blue black adds a subtle midnight-blue tint that appears in sunlight and under bright lights. Together, they suit almost every skin tone, make eyes look brighter, and give even a simple cut a expensive, finished look.
Whether you want a dramatic change or a quiet refresh, this collection covers every length and texture. You will find sharp bobs, flowing layers, soft curls, braids, buns and bold colour placements, each one chosen to show off the shine and depth of dark hair. Use these 36 ideas to find the style that fits your hair type, your routine and the amount of drama you want, then take your favourite to your colourist as a clear starting point.
1. Classic Jet Black Sleek Bob

The classic jet black sleek bob is the definition of polished hair. Cut to chin length with clean, sharp ends and a centre part, it frames the face beautifully and lets the deep black colour do all the talking. The gloss of jet black hair makes the shape look even sharper, so this style works best when the hair is smooth, healthy and freshly trimmed.
To keep this bob looking its best, blow dry it with a round brush or run a flat iron through the lengths for a mirror finish. A lightweight shine serum on the ends adds gloss without weighing the hair down. This is a brilliant choice if you want a low-effort style that still looks intentional every single day.
2. Blue Black Long Layers

Blue black long layers are perfect if you love long hair but want movement and shape. The layers stop the length from looking heavy, while the blue black shade adds a cool, inky depth that catches the light as the hair moves. Indoors it reads as rich black, and outdoors the blue tint comes alive.
Ask your stylist for long, soft layers that start around the cheekbones and blend through the ends. This keeps the shape flattering without removing too much thickness. Style with a large barrel curling iron for gentle bends, or leave it straight to show off the colour at its glossiest.
3. Jet Black Glass Hair

Jet black glass hair is all about shine. The hair is cut blunt, kept perfectly straight and polished until it reflects light like glass. Because jet black is the darkest shade available, it shows shine better than any other colour, making this one of the most striking looks in this whole collection.
The secret is healthy hair and the right finishing products. Use a smoothing shampoo, a heat protectant before straightening, and a tiny amount of gloss oil on the mid-lengths and ends. Regular trims keep the blunt ends crisp, and a colour gloss treatment between dyes keeps the black looking fresh rather than faded.
4. Midnight Blue Black Balayage

Midnight blue black balayage is a softer way to wear blue. Your colourist hand-paints deep blue tones through the mid-lengths and ends, leaving your natural black roots untouched. The result is a gradual, lived-in blend that looks expensive and grows out gracefully without a harsh line.
This style suits long and medium hair best, especially when worn wavy, because the waves reveal the blue dimension. Use a colour-safe shampoo and wash in cool water to slow fading. A blue-toned conditioner once a week helps keep the midnight tone rich between salon visits.
5. Blue Black Ombre Ends

Blue black ombre ends give you a bold colour change without colouring your whole head. The top stays jet black, then the colour melts gradually into deep blue black at the tips. It is playful, modern and easy to grow out, because the darkest part sits at the roots where regrowth blends in naturally.
This look is especially beautiful on long, straight hair, where the gradient is easy to see. Keep the ends moisturised with a leave-in conditioner, since lightened ends can dry out faster than the roots. A quick gloss refresh every few weeks keeps the blue from turning dull.
6. Jet Black Pixie Cut

A jet black pixie cut is bold, confident and wonderfully easy to style. The short, textured top and neat tapered sides show off your face and bone structure, while the deep black colour adds drama and shine. It is a brilliant option if you want a fresh start or a style that dries in minutes.
Style it with a small amount of texturising paste, pushing the top forward or to the side for different looks. Because the cut is short, regular trims every four to six weeks keep the shape sharp. Jet black also makes a pixie look thicker and fuller, which is a bonus for fine hair.
7. Blue Black Mermaid Waves

Blue black mermaid waves are long, soft and romantic. The waves are loose and flowing rather than tight curls, and the blue black shade gives them a deep, ocean-like depth. This style looks stunning in photos and at evening events, where the light catches every wave.
Create the waves with a large curling wand, curling away from the face, then brush them out gently for a soft finish. A sea salt spray adds texture without stiffness. Because the hair is long, use a deep conditioning mask weekly to keep the ends healthy and the colour glossy.
8. Jet Black Curtain Bangs

Jet black curtain bangs soften a long hairstyle without a big commitment. The bangs part in the middle and sweep to each side, framing the cheekbones and drawing attention to the eyes. With jet black hair, the contrast between the dark hair and the skin makes the framing effect even stronger.
Blow dry the bangs with a round brush, rolling them away from the face for that signature curtain shape. They grow out gracefully into face-framing layers, so you do not need constant trims. This is a great first step if you have always wanted bangs but are nervous about a full fringe.
9. Blue Black Peekaboo Highlights

Blue black peekaboo highlights are the perfect hidden surprise. The top layer stays jet black, while panels of blue black underneath flash through when the hair moves, is tucked behind the ear, or is tied up. It is subtle in a meeting and striking on a night out.
Ask your colourist to place the blue panels underneath the top layer, around the nape and behind the ears, so they stay hidden until you want to show them. This placement also means less visible regrowth. Wear your hair down for a secret pop of colour, or half up to reveal the blue more boldly.
10. Jet Black Wolf Cut

The jet black wolf cut mixes a shaggy, layered top with longer, wispy ends. It is edgy, textured and full of movement, and the deep black colour makes the layers look sharp and defined. This cut suits thick hair especially well, because the layers remove weight while keeping the length.
Style it with a texturising spray and rough dry with your fingers for a lived-in finish. A little volume at the crown is the key to this look, so lift the roots while blow drying. If you like bold, low-maintenance styles with attitude, the wolf cut is hard to beat.
11. Blue Black Braided Crown

A blue black braided crown is elegant and perfect for weddings, parties and special occasions. The hair is braided around the head like a crown, and the blue black shade gives the braid beautiful depth, with each twist catching the light differently. It looks intricate, but the effect is soft and romantic rather than severe.
This style works best on medium to long hair with some texture, so the braid holds its shape. Add a little texturising powder before braiding for grip, and pin the ends neatly underneath. Leave a few soft strands around the face to keep the look relaxed and modern.
12. Jet Black Blunt Lob

The jet black blunt lob sits at shoulder length with a sharp, straight-across cut. It is the ideal middle ground between a bob and long hair, and the blunt ends make the hair look thicker and healthier. Jet black colour makes the clean line of the cut stand out beautifully.
Wear it straight for maximum impact, or add a slight bend at the ends for softness. Because the ends are blunt, they show split ends more easily, so keep up with trims and use a heat protectant every time you style. This lob suits almost every face shape and grows out gracefully.
13. Blue Black Curls

Blue black curls are full of life and shine. Defined curls show off the blue dimension in a way straight hair cannot, because each curl catches the light from a different angle. The result is rich, dimensional dark hair that looks vibrant even without any other colour.
Define your curls with a curl cream or mousse, scrunching the product in while the hair is damp. Diffuse on a low heat to protect the curl pattern and reduce frizz. A silk pillowcase helps curls last overnight, and a weekly deep conditioner keeps the colour glossy and the curls bouncy.
14. Jet Black Slicked Back Bun

The jet black slicked back bun is sleek, elegant and timeless. The hair is brushed back smoothly from the face and gathered into a neat low bun, with no flyaways in sight. Jet black hair makes this style look especially polished, because the shine emphasises the smooth finish.
Use a strong-hold gel or smoothing cream and a fine-tooth comb to get the sleek base, then secure the bun with pins that match your hair colour. This style is ideal for work, formal events and hot days when you want your hair completely out of the way. Add a middle or side part to change the mood.
15. Blue Black Money Piece

A blue black money piece places two face-framing strands of blue black at the front of jet black hair. It brightens the face instantly, draws attention to your eyes, and adds a modern, fashion-forward touch without colouring the whole head. It is one of the easiest ways to try blue black for the first time.
The front strands frame the face, so they look best when they are slightly lighter and bluer than the rest of the hair. Style the front pieces with a slight bend away from the face. Because only a small section is coloured, upkeep is simple and regrowth is barely noticeable.
16. Jet Black Feathered Layers

Jet black feathered layers bring softness and movement to long dark hair. The layers are feathered at the ends so they flick out gently, giving the style a light, airy feel instead of a heavy curtain of black. It is a flattering, classic shape that never looks dated.
Blow dry the layers with a round brush, flicking the ends outward for the feathered effect. A lightweight volumising mousse at the roots stops the style from falling flat. This cut is especially good for thick hair, because the feathering removes bulk while keeping the length.
17. Blue Black Underlights

Blue black underlights colour only the underneath layer of the hair, leaving the top jet black. When your hair is down, you see just a hint of blue at the ends. When you tie it up or flip it, the blue is revealed in full. It is a clever, versatile placement for anyone who wants colour with control.
This technique also protects the top layer from damage, since only the underneath hair is coloured. Ask for the underlights to sit a few inches from the roots so regrowth stays hidden. A high ponytail or a half-up style is the best way to show off the blue.
18. Jet Black Hollywood Waves

Jet black Hollywood waves are pure old-school glamour. The hair is parted deeply to one side and styled into smooth, uniform waves that fall over one shoulder. Jet black is the perfect colour for this look, because its high shine makes the waves look liquid and luxurious.
Set the waves with large rollers or a curling iron, brushing them out into one smooth wave pattern and pinning them while they cool. A strong-hold shine spray keeps the waves in place all evening. This is a stunning choice for weddings, parties and any occasion where you want to look unforgettable.
19. Blue Black Space Buns

Blue black space buns are playful, youthful and full of personality. Two buns sit high on the head, and the deep blue black colour gives them a cool, modern edge. This style is perfect for festivals, concerts and fun days out when you want your hair to make a statement.
Part the hair down the middle, twist each side into a bun and secure with pins and a hair tie. Leave a few face-framing strands loose for a softer finish, or keep it sleek for a sharper look. A little hairspray keeps the buns tidy, and the style works on both straight and wavy hair.
20. Jet Black Long Straight Hair with a Centre Part

Very long, straight jet black hair with a centre part is simple, striking and timeless. The symmetry of the centre part and the uniform black length create a clean, dramatic silhouette. There is nowhere for damage or dullness to hide, so healthy, glossy hair is what makes this look work.
Keep the length in top condition with regular trims, a weekly hair mask and minimal heat. When you do straighten, use a heat protectant and a flat iron on a moderate temperature. This style suits oval and round faces especially well, and it looks just as good in a ponytail as it does worn down.
21. Blue Black Fishtail Braid

A blue black fishtail braid is detailed, beautiful and surprisingly wearable. The fishtail pattern creates a fine, woven texture that shows off the blue tones in the hair, especially in sunlight. Worn over one shoulder, it is romantic and relaxed, and it keeps long hair tidy all day.
Start with slightly textured hair so the braid holds, then weave small sections from each side into the centre. Gently pull the braid apart at the edges for a fuller, softer finish. Secure with a clear elastic and wrap a small strand of hair around it to hide the band for a polished result.
22. Jet Black Shag

The jet black shag is a cool, textured cut with choppy layers and a soft fringe. It has a relaxed, rock-inspired feel, and the black colour makes the choppy texture look sharp and deliberate. This cut adds volume at the crown and movement through the ends, so it suits fine to medium hair very well.
Style it with a texturising spray and scrunch the layers while blow drying for a lived-in finish. The shag grows out well, because the layers blend naturally as they get longer. It is a great choice if you want a low-maintenance cut that still looks styled.
23. Blue Black Top Knot

A blue black top knot is the ultimate easy updo. The hair is gathered high on the crown and twisted into a neat knot, showing off the blue black colour from every angle. It is practical, stylish and perfect for busy days, workouts and warm weather.
Smooth the hair up with a brush and secure it with a strong elastic before twisting and pinning the knot. A little smoothing serum tames flyaways, while a few loose strands at the front soften the look. This style also makes a great base for a scarf or a statement hair accessory.
24. Jet Black Side Swept Waves

Jet black side swept waves are soft, feminine and flattering. The hair is swept to one side in gentle waves, opening up the face and creating a beautiful, asymmetrical shape. The deep black shine makes the waves look smooth and healthy, even with minimal styling.
Curl the hair in large sections away from the face, then sweep it to one side and pin it loosely behind the ear on the opposite side. A light-hold hairspray keeps the waves soft rather than stiff. This is a lovely choice for dates, dinners and photographs.
25. Blue Black Dip Dye Ends

Blue black dip dye ends look as though the tips of the hair have been dipped in deep blue ink. The line between black and blue is more defined than an ombre, which gives this style a bold, graphic feel. It is a fun, low-commitment way to wear blue, because only the very ends are coloured.
This look works best on long, straight or slightly wavy hair, where the dipped ends are easy to see. Trim the ends regularly, since coloured tips can become dry. If you ever tire of the blue, you can simply cut the ends off without touching the rest of your hair.
26. Jet Black Curly Afro

A jet black curly afro is bold, beautiful and full of volume. The rounded shape frames the face perfectly, and the deep black colour gives the curls a rich, glossy depth. This style celebrates natural texture and makes a powerful statement with very little styling.
Keep the curls hydrated with a leave-in conditioner and a curl-defining cream, and pick the roots gently for volume. A satin bonnet or pillowcase at night protects the shape and reduces frizz. Regular deep conditioning keeps the black colour shiny and the curls soft and defined.
27. Blue Black Half Up Half Down

Blue black half up half down hair gives you the best of both worlds. The top section is pulled back and secured, keeping hair out of your face, while the rest flows freely down your back. The blue black shade looks especially dimensional in this style, because the tied section reveals the colour underneath.
Secure the top half with a small elastic or a claw clip, and add a few waves through the loose lengths. You can keep it simple for everyday wear, or add a braid to the top section for a special occasion. It suits every hair length from shoulder length upwards.
28. Jet Black French Twist

The jet black French twist is a classic updo that never looks out of place. The hair is swept up and twisted into a vertical roll at the back of the head, creating a smooth, sculpted shape. Jet black hair makes the twist look especially sleek, because the shine highlights the smooth surface.
Use bobby pins in the same colour as your hair to secure the twist invisibly, and smooth the top with a brush and a little gel. Leave a few soft strands at the front for a romantic finish, or keep it completely sleek for a formal event. This updo works best on medium to long hair.
29. Blue Black Sleek Ponytail

A blue black sleek ponytail is sharp, modern and effortlessly chic. The hair is pulled back smoothly into a high ponytail, and the deep blue black colour adds a cool tint that catches the light as the ponytail swings. It is a favourite for both everyday wear and evening looks.
Brush the hair back with a smoothing cream and secure it tightly, then wrap a strand of hair around the elastic to hide it. Straighten the ponytail itself for a sleek finish, or add a slight curl at the ends. A quick mist of shine spray is the perfect finishing touch.
30. Jet Black Beach Waves

Jet black beach waves are relaxed, textured and easy to wear. The waves are loose and slightly messy, giving the hair a natural, sun-kissed feel even though the colour is deep and dark. The contrast between the casual texture and the polished black shade is what makes this style so appealing.
Create the waves with a curling wand, alternating the direction of each curl, then shake them out with your fingers. A texturising spray adds grip and hold without stiffness. This style is perfect for holidays, weekends and anyone who wants a low-effort look with plenty of personality.
31. Blue Black Low Bun with Face Framing Strands

A blue black low bun with face framing strands is soft, elegant and very flattering. The bun sits low at the nape, while two loose strands frame the face and soften the whole look. The blue black colour adds depth to the bun and makes the face framing pieces stand out gently.
Gather the hair loosely at the nape and twist it into a bun, leaving the front strands free. Curl those strands lightly away from the face for a romantic finish. This style is ideal for weddings, work events and any day when you want to look polished without trying too hard.
32. Jet Black A-Line Bob

The jet black A-line bob is longer at the front and shorter at the back, creating a sharp, angled shape that elongates the face. The clean lines and deep black colour make it look modern and confident, and it suits straight and slightly wavy hair equally well.
Style it straight to show off the angle, or add a subtle bend through the front sections. The A-line shape needs regular trims to keep the angle crisp, so book a trim every six weeks. A shine serum on the ends keeps the black looking glossy and healthy.
33. Blue Black Dutch Braids

Blue black Dutch braids are neat, practical and full of detail. Two braids run from the front of the head to the back, sitting on top of the hair so the woven pattern is easy to see. The blue black shade makes the braid texture stand out, with light catching each twist.
Start with damp, detangled hair and braid tightly for a neat finish, or pull the braids apart gently for a softer, fuller look. This style keeps hair out of the way for sport, work and travel, and it lasts for a day or two. Add small accessories at the ends for a playful touch.
34. Jet Black High Ponytail

A jet black high ponytail is bold, lifted and full of energy. The hair is pulled high on the crown, which lifts the face and creates a long, sleek line down the back. Jet black hair makes this simple style look dramatic, because the shine and the height draw the eye immediately.
Brush the hair up smoothly and secure it firmly, then add volume at the crown by gently backcombing the roots before you tie it. Wrap a strand around the base for a polished finish. This ponytail works for the gym, for work and for a night out, just by changing your makeup and outfit.
35. Blue Black Soft Curls with Bangs

Blue black soft curls with bangs combine romance and structure. The curls are soft and bouncy, while the straight bangs frame the forehead and give the style a defined shape. The blue black colour adds depth to the curls and makes the bangs look glossy and neat.
Style the bangs straight with a round brush, and curl the lengths with a medium barrel iron, brushing the curls out for softness. Keep the bangs trimmed so they sit just above the eyebrows. This style suits heart-shaped and oval faces especially well.
36. Jet Black to Blue Black Colour Melt

A jet black to blue black colour melt is the most seamless way to wear both shades. There is no visible line where one colour ends and the other begins. Instead, the black at the roots melts gradually into deep blue through the lengths, creating a smooth, dimensional finish that looks natural and expensive.
This technique needs a skilled colourist, because the blending is everything. Worn wavy, the melt is at its most visible, with the blue appearing and disappearing as the hair moves. Use colour-safe products and cool water when washing to keep the blend rich and the transition smooth for as long as possible.

Frequently Asked Questions
What is the difference between jet black and blue black hair colour?
Jet black is a pure, deep black with no visible undertone, while blue black has a cool blue tint that shows in sunlight and bright light. Jet black looks warmer and glossier indoors, whereas blue black looks cooler and more dimensional. Both are very dark, so the difference is subtle until the light catches the blue.
Does blue black hair suit all skin tones?
Yes, blue black suits most skin tones, but it looks especially striking on cool and neutral undertones because the blue tint complements them. If you have a warm skin tone, ask your colourist for a softer blue black with less blue at the front, so the colour frames your face without washing you out.
How do I stop blue black hair colour from fading?
Wash your hair less often, use cool water and a colour-safe, sulphate-free shampoo, and avoid too much sun and heat styling. A blue-toned conditioner or a colour gloss treatment every two to three weeks helps refresh the blue tint. Deep conditioning also keeps the hair shiny, which makes the colour look richer for longer.
Will jet black hair dye damage my hair?
Jet black dye is usually gentler than lightening, because it deposits colour rather than lifting it, but any permanent dye can dry the hair out over time. Keep your hair healthy with regular conditioning treatments, limit heat styling, and leave enough time between colour appointments. A semi-permanent jet black is a gentler option if you want to try the shade first.
How often should I touch up jet black or blue black hair?
Most people need a root touch-up every four to six weeks, depending on how fast their hair grows and how visible their natural colour is. If you have balayage, ombre or peekaboo placement, you can wait longer, because the regrowth blends in more naturally. A gloss refresh between appointments keeps the colour looking fresh without a full dye.
