Blue and purple hair has a pull that is hard to ignore. The two colours sit close together, so they blend without clashing, yet the result still looks bold. You can go soft and dreamy, or dark and dramatic, and still stay inside the same colour family.
What changes from one idea to the next is not just the shade. You will see short pixies and long layers, tight curls and smooth straight hair, ombre ends, chunky highlights, braids, undercuts and two tone colour. Some looks keep the colour close to the roots, while others save it for the lengths and ends.
Each idea below has a photo, a note on who it tends to suit, and a practical point to help you judge it. Look at the curl shape first, then the length, then the way the blue and purple are placed. Save two or three favourites to compare before you decide.

1. Periwinkle Pixie

This pixie pairs pastel blue and purple with soft pink highlights through the top. The texture stays light and piecey, so the colour reads as playful rather than heavy. Shorter sides keep the shape neat and let the longer top do the talking.
It suits fine to medium hair and anyone who likes a short cut with a clear colour statement. A round or oval face shape works well here, because the height on top adds balance. Keep the pink highlights in mind if you wash often, as pastel tones fade first. Wash in cool water and use a colour safe shampoo to stretch the time between refreshes. This is a confident short look, and it wears best when the cut stays tidy.
2. Dark Root Violet Face Frame

What if you want vivid colour without colouring every strand? This straight style keeps dark roots at the crown and places a vivid violet section around the face. Blue tones run through the lower lengths, so the colour builds as your eye moves down the hair.
It flatters dark natural hair and anyone growing out colour, because the dark root softens regrowth. Straight or lightly waved hair will show the face frame most clearly. Ask for a strong violet panel at the front and a cooler blue through the ends, rather than one flat shade. Do not overdo heat on the violet section, as repeated straightening can dull that bright edge first.
3. Twilight Layers

Long layers carry a wash of blue, purple and pink here, with the colours melting into each other instead of sitting in hard blocks. The layering matters, because each layer catches a slightly different shade as the hair moves.
This is a good match for thick hair that can hold long layers without looking thin at the ends. It also suits anyone who wants colour that changes in different light. Keep the ends in good condition, since layered ends show dryness quickly. A leave in conditioner and a trim every few weeks will keep the colour looking smooth rather than frayed.
4. Bright Bob
PinPhoto credit: Instagram
A layered bob gets a fresh lift from pastel purple with blue highlights woven through. The shape is short enough to feel modern, but the layers stop it from looking blunt or heavy. Colour sits through the lengths, so the bob reads as bright from every side.
It suits medium to thick hair and a jaw to chin length cut. If your hair is very fine, ask for light layers only, so the ends keep some weight. The mistake to avoid is washing with hot water every day, which can wash pastel purple out fast. Rinse cool, and let the bob air dry when you can.
5. Opal Braid

This braid takes its cue from opal, with purple melting into blue and soft pastel tones running through the plait. The braid itself adds shape, so the colour shifts as each section crosses over the next. It feels softer than a solid galaxy colour, and a little more romantic.
Long hair works best, because a braid needs length to show the full colour change. It also suits anyone who likes a style they can wear loose at the front and neat at the back. Braid on slightly damp, conditioned hair to reduce frizz, and do not pull the braid too tight at the hairline. Tight braiding can snap fine, colour treated hair.
6. Split Purple and Blue

Here the colour is split cleanly, with vivid purple over the top layer and bright blue underneath. When the hair moves, the blue flashes through, which makes a straight style look far less plain. The contrast is clear, but both colours still belong to the same family.
Straight, long hair shows this split best, and it suits anyone who wants a bold reveal rather than a blend. A centre or side part will change how much blue shows, so try both before you settle. Keep the two colours from bleeding into each other by washing with cool water and drying the layers separately when they are freshly coloured.
7. Mermaid Mane
PinPhoto credit: Instagram
Long waves carry purple and teal blue in this mermaid style, with the colour deepening and lightening through the waves. The effect is dark and colourful at once, like water at night rather than a bright daytime blue. Waves help, because they break the colour into shifting bands.
It suits long, wavy or curly hair that already has natural movement. Straight hair can still work, but you will need to add waves to get the same depth. Avoid brushing dry waves, as that can turn the colour into a flat fuzz. Use a wide tooth comb on damp hair and a light curl cream instead.
8. Dark Unicorn Waves
PinPhoto credit: Instagram
Dark unicorn colour does not have to mean pastel. Here a navy base holds deep purple and blue green tones, so the colour looks dramatic up close and subtle from a distance. Long waves let each tone appear in turn, rather than competing all at once.
This is a strong choice if your natural hair is dark, because new growth blends in more easily than it would with a light pastel. It also suits anyone who wants vivid colour for work or everyday life without a loud, light finish. The main risk is over washing, which can dull the navy base. Space out washes and use a tinted conditioner made for dark vivid colour.
9. Starry Spirals
PinPhoto credit: Instagram
Soft purple and teal balayage runs through loose, medium curls in this gentle take on galaxy colour. The curls start below the roots, so the colour looks like it is unfolding rather than sitting flat on the head. Nothing here is harsh, and that softness is the point.
It flatters medium length hair with a natural wave or loose curl pattern. If your hair is straight, a large barrel curling iron will give a similar spiral without tight ringlets. Do not use a high heat setting every day, as heat can fade teal quickly. Let curls cool fully before you touch them, so they hold their shape longer. Wear it soft, and let the colour do the talking.
10. Purple Root Blue Bob

Why choose between purple and blue when a bob can hold both? This short, wavy bob starts with dark purple at the roots and melts into electric blue through the lengths and ends. The wave keeps the colour from looking flat, and the short length keeps the change feeling sharp.
It suits thick or medium hair cut to bob length, and anyone who likes colour that is easy to refresh. Short hair means less product and faster drying, which helps vivid colour last. Avoid heavy oils on the roots, as they can make dark purple look dull. A light, colour safe serum on the ends is enough.
11. Geometric Undercut
PinPhoto credit: Instagram
A short galaxy cut gets an edge from a shaved undercut at the nape, with a diamond shape worked into the shaved section. A large braid adds texture on top, so the style mixes soft colour with a sharp, graphic detail. Dark blue and purple strands keep the whole look tied together.
It suits short hair and anyone who likes a detail that only shows when the hair moves or is lifted. If you wear your hair down most days, keep the undercut at the nape rather than the sides, so it stays a surprise. The shaved section will need regular tidying, or the diamond shape will blur as it grows out.
12. Punchy Layers
PinPhoto credit: Instagram
Blue, teal and purple highlights run through layered hair here, giving depth without colouring the whole head one shade. Layers open the hair up, so highlights that would hide in a blunt cut become visible. The result is punchy, but still wearable day to day.
Medium to long hair with layers suits this best, especially if your base is dark enough for the highlights to stand out. Ask for highlights placed through the mid lengths and ends, not just on the top layer, or the colour can look thin from behind. Do not skip conditioner on highlighted hair, as lightened sections dry out faster than the rest.
13. Chunky Galaxy Highlights
PinPhoto credit: Instagram
Instead of a smooth ombre, this look uses chunky highlights to build galaxy colour. Teal forms the base, with bold pink and purple sections placed in wide pieces. Chunky colour reads more graphic than fine highlights, and it is easier to see from a distance.
It suits straight or lightly waved hair, where wide sections stay visible instead of tangling into each other. If your hair is very curly, ask for slightly wider sections still, or the chunky effect can get lost in the curl. The mistake to avoid is overlapping bleach on already lightened pieces at a refresh, which can weaken the hair. Keep a record of which sections were lightened last time.
14. Blue to Violet Shoulder Waves
PinPhoto credit @mariadeoleo01
Shoulder length waves carry electric blue at the roots and crown, melting into violet through the lengths. The wave is loose, so the colour shifts gently instead of changing in a hard line. It is bright, but the shoulder length keeps it easy to manage.
This length suits most face shapes, and it is a good middle ground if long vivid hair feels like too much upkeep. Wavy hair will show the blend best, while straight hair will show a cleaner blue to violet change. To keep the blue vivid, avoid clarifying shampoo unless you need it, as it can strip blue faster than other shades.
15. Dizzying Double Braid
PinPhoto credit: Instagram
Two braids turn a simple style into something far more striking when one side leans teal and the other leans purple. The braids keep the colour in neat, readable sections, so you can see exactly where one shade ends and the next begins. On its own, a double braid can look demure, but this colour changes the mood completely.
Long to medium hair works best, and it suits anyone who wants a braided style that still feels bold. Keep the braids even in size, or the colour balance will look off. A light hold spray will keep flyaways down without making colour treated braids stiff or crunchy.
16. Pretty Pearl
PinPhoto credit: Instagram
Silver tones mixed into blue and purple give this short style a pearly finish, with the colour shifting as light hits it. Washed pastel blue and pink sit through the lengths, and a small top knot adds a simple weekend shape. It looks delicate, but the silver keeps it from looking washed out.
Short hair suits this best, and it is a good option if you like pastel colour without a long, high maintenance style. Fine hair can work here, as the top knot adds height without needing much length. Do not use purple shampoo too often on this look, as it can push the pastel blue toward grey. Use it only when brassiness actually appears.
17. Technicolor Ombre
PinPhoto credit: Instagram
A bob carries a blue to lavender ombre here, with blue at the top melting into a softer lavender at the ends. The change is gradual, so the bob looks delicate even though the colour is strong. A bob length also means the ombre is easy to see in full, without long lengths hiding the transition.
It suits straight or lightly waved bob length hair, and anyone who wants ombre without committing to a very long style. If your hair is thick, ask for the ombre to start a little lower, so the top does not look too dark against the light ends. Protect the lavender ends from sun and heat, as light pastel ends fade and dry first.
18. Short Curly Galaxy Curls

Short, tight curls hold deep purple and electric blue in close, swirling sections. Each curl catches a different shade, so the colour looks three dimensional even in a short cut. This is galaxy colour at its most textured, and it does not need length to make an impact.
It flatters naturally curly or coily hair, and anyone who wants vivid colour without straightening to show it. A curl defining cream will help the colour sections stay separate instead of blending into one shade. Do not brush curls dry, as that will break the curl pattern and dull the blue. Scrunch with damp hands and let the curls set. Wear it with confidence, because a short curly galaxy cut is hard to ignore in the best way.
19. Stained Glass Sides
PinPhoto credit: Instagram
A fauxhawk shape gives this look its structure, with bold colour on the sides and soft pastel spirals on top. The contrast between the two areas is what makes it feel like stained glass, with strong colour beside softer, lighter tones. It is a bold shape, but the pastel top keeps it from feeling harsh.
It suits short to medium hair that can hold a fauxhawk shape, and anyone who likes a style with a clear focal point. If your hair is fine, use a light styling product for lift rather than a heavy wax, which can flatten the top spirals. Keep the side colour refreshed more often than the top, as bold side colour shows fading sooner.
20. Rainbow Birthday Waves
PinPhoto credit: Instagram
Medium length waves carry a rainbow tint over a purple and blue base, with extra colours peeking through the waves. The look is fun and a little nostalgic, without needing every colour of the rainbow in equal amounts. Purple and blue stay in charge, while the other tones act as highlights.
It suits medium length, wavy hair and anyone who wants a playful colour that still reads as blue and purple first. If you work in a strict setting, keep the extra rainbow tones to the lower layers, where they show less. Use a colour safe mask once a week, as multi tone hair dries out faster than a single colour.
21. Tri-Color Fishtail
PinPhoto credit: Instagram
Instead of colouring the whole head, this fishtail braid uses blue and purple as an accent, with a bold coloured section running through the middle of the hair. The fishtail pattern breaks the colour into small, even pieces, so it looks detailed rather than loud. Worn loose, the accent can hide, and worn braided, it takes centre stage.
Long hair suits a fishtail best, and it is a good first step if you are not ready for full head vivid colour. It also suits anyone who likes to change a look without recolouring, since you can braid or leave the accent loose. Keep the accent section conditioned, as it is usually lightened more than the rest of the hair.
22. Purple Haze
PinPhoto credit: Instagram
Could a short curly style carry this much colour? Yes, and this pastel purple look proves it. Volume and two tone colour give the curls a soft haze, with lighter and deeper purple tones sitting side by side. The curls do the work, so the colour does not need length to stand out.
It flatters short, curly hair and a face shape that benefits from width and height around the crown. If your curls are tight, ask for a cut that leaves room for shrinkage, so the finished length still sits where you want it. Do not use a fine tooth comb on dry curls, as it will break the curl clumps and turn the haze into frizz.
23. Braided Half-Updo
PinPhoto credit: Instagram
Long hair with few layers can look flat, but braids and twists in a half up style change that at once. Here dark blue hair holds green and purple highlights, and the braided top section lifts the colour where it is most visible. The rest of the hair stays loose, so you get structure and movement in one style.
It suits long, straight or lightly waved hair, and anyone who wants a quick change without cutting or recolouring. A half up braid also works well for thick hair, as it takes weight off the face. Secure the braid with a snag free tie, and do not pull the front sections too tight, or the style will feel uncomfortable by the end of the day.
24. Rocking Rainbow
PinPhoto credit: Instagram
Black hair can hold rainbow colour, and this look shows it with subtle highlights that shimmer through dark strands. Blue and purple lead, with other rainbow tones woven in as a ribbon effect. From a distance the hair looks dark, and up close the colour reveals itself.
It suits dark, long or medium hair, especially if you want vivid colour that is not obvious in every light. It is also a good option for a first vivid colour, as the dark base keeps regrowth less noticeable. The mistake to avoid is expecting the highlights to stay bright without upkeep, as rainbow tones on dark hair fade unevenly. A gloss or refresh on the highlighted sections will keep the ribbon effect clear.
25. Two-Tone Dip Dye Bob
PinPhoto credit: Instagram
A blue bob with purple dip dye ends is one of the simplest ways to wear two colours. The top stays blue, the ends turn purple, and the blend between them does the rest. No foils, no complex sectioning, just a clear two tone change that is easy to read.
It suits bob length hair and anyone who is new to vivid colour or unsure about highlights. A bob also means a faster refresh, since only the ends need the purple topped up. Keep the ends moisturised, as dip dyed ends are usually lightened and can split if they dry out. Trim them little and often, and the two tone line will stay clean. This is a low fuss way to wear a bold colour, and it still turns heads.
How to Care for Blue and Purple Hair
- Wash less often, and rinse in cool water to slow fading, especially for pastel blue and lavender ends.
- Use a colour safe, sulphate free shampoo, and add a colour depositing conditioner only when the shade actually starts to fade.
- Keep heat low, use a heat protectant, and let waves and curls cool before you touch them.
- Condition lightened sections well, and trim split ends little and often so colour stays smooth.
- Protect hair from strong sun and chlorine, which can shift blue toward green and dull purple.
- Keep a note of your shades and placement, so a refresh does not overlap bleach on already lightened hair.
Frequently Asked Questions
Does blue and purple hair suit dark hair?
Yes. Dark hair suits deep navy, violet and purple tones well, and a dark base can make regrowth less obvious. Lighter pastel blue and lavender will need more lightening first, so expect more upkeep if you choose a very light shade.
How long does blue and purple hair colour last?
It depends on the shade and how often you wash. Deep blue and purple can last several weeks, while pastel blue, lavender and teal often fade faster. Cool water, fewer washes and colour safe products will help it last longer.
Will blue hair turn green as it fades?
Blue can shift toward green as it fades, especially on yellow toned, lightened hair. A purple toned conditioner or a refresh can correct the shift, and avoiding chlorine and strong sun will slow it down.
Can I try blue and purple hair without colouring my whole head?
Yes. Try an accent section, a fishtail braid with coloured pieces, dip dye ends, or hidden underlayers. Those options let you test the colour family before you commit to a full head.
What should I ask for if I want galaxy hair?
Ask for a blend of blue and purple, not one flat shade, and show photos of the placement you like, whether that is ombre, balayage, chunky highlights or a split colour. Mention your length, curl pattern and how much upkeep you are happy with.
Is blue and purple hair hard to maintain?
It needs more care than a natural colour, but it is manageable. The main work is washing less, using cool water, conditioning lightened hair, and refreshing pastel or bright ends when they fade.
Final Thoughts
Blue and purple hair works because the colours blend well, but the right version depends on your length, curl pattern and upkeep. Start with the shape you already like, then choose whether you want a blend, an ombre, a split, or an accent. That order makes the choice simpler than starting with a shade alone.
Check the practical points too. Pastel ends fade fastest, dark bases hide regrowth best, and short cuts are usually quicker to refresh. A colour that fits your washing routine and your hair type will look better for longer than a colour you have to fight to maintain.
Save two or three photos from this list, compare the curl shape, the length and the colour placement, and keep the one that still excites you after a second look. That is usually the blue and purple hair idea worth trying first.
