Halloween hairstyles for long hair open up a world of costume possibilities, from witchy waves to gothic glamour. Long hair is the ultimate Halloween accessory — it can be braided, teased, slicked, curled, and twisted into character-defining styles that elevate even the simplest costume. Whether she is dressing as a classic witch, a vampire queen, a dark mermaid, or a haunted fairy, the right hairstyle does half the acting. These fifteen Halloween hairstyles for long hair require no salon visit and work with basic tools most people already own: a curling iron or wand, bobby pins, a teasing comb, and hairspray. Each style below includes step-by-step instructions, who it suits best, and a pro tip for making it last through a full night of trick-or-treating or partying.
1. Witchy Loose Waves
The witchy loose waves look is the classic Halloween hairstyle for long hair, and it suits everything from a traditional witch to a dark bohemian costume. She starts by applying a heat protectant, then wraps large sections of hair around a 1.25-inch curling wand, leaving the ends out for a lived-in finish. After curling, she runs her fingers through the waves to break them up and mists with texturizing spray. This style works best on hair that is at least shoulder-blade length, and it flatters round and oval faces by adding vertical lines. It pairs perfectly with a pointed hat, a black dress, and smoky eye makeup. Pro tip: curl each section in alternating directions for the most natural, spellbinding volume.
2. Morticia Addams Sleek Straight
Nothing says gothic elegance like the Morticia Addams sleek straight style. She straightens her hair in thin sections with a flat iron, keeping the part razor-sharp down the middle. A shine serum or smoothing oil tames flyaways and creates that glossy, almost wet-looking finish. This Halloween hairstyle for long hair suits women with naturally straight or slightly wavy hair best, since it relies on sleekness rather than volume. It is ideal for a Morticia costume, a vampire, or any dark aristocratic character. The look frames the face dramatically and photographs beautifully under party lighting. Pro tip: run the flat iron over each section twice slowly, and finish with a cold blast from the dryer to lock in the glass-like shine.
3. Mermaid Waves for a Siren Costume
Mermaid waves bring a hypnotic, otherworldly quality that makes this one of the most popular Halloween hairstyles for long hair. She creates deep, uniform waves using a triple-barrel waver or by braiding damp hair overnight and releasing it in the morning. Sea-salt spray adds the gritty texture that sells the just-emerged-from-the-ocean illusion. This style is perfect for mermaid, siren, sea witch, and ocean goddess costumes. It suits thick, long hair particularly well, since density gives the waves their dramatic depth. Shell clips, starfish pins, or a seashell crown complete the transformation. Pro tip: sprinkle a little temporary blue or teal hair chalk through the mid-lengths for an underwater glow that washes out easily.
4. Braided Crown With Ribbons
The braided crown with ribbons gives long hair a romantic, slightly haunted storybook feel. She parts her hair down the middle, braids each side into a Dutch or French braid, then wraps them over the top of the head like a crown, pinning the ends underneath. Black, deep red, or purple ribbons woven through the braids add the Halloween touch. This style suits women with medium to thick long hair and works beautifully for fairy tale, dark princess, or woodland spirit costumes. It keeps hair completely off the face, making it practical for a long night of festivities. Pro tip: pancake the braids by gently pulling the edges outward before pinning — this makes thin hair look twice as thick.
5. Vampire Queen High Ponytail
The vampire queen high ponytail is fierce, regal, and surprisingly easy. She flips her head upside down, gathers all her hair into a high ponytail at the crown, and secures it with a strong elastic. Then she wraps a small section of hair around the base to hide the elastic and pins it underneath. For extra drama, she backcombs the ponytail for volume or adds clip-in extensions for extreme length. This Halloween hairstyle for long hair suits oval, heart, and diamond face shapes best. It works for vampire, dark queen, and dominatrix-adjacent costumes, and it keeps hair out of the way while dancing. Pro tip: add two bobby pins in an X shape under the ponytail base for invisible lift that lasts all night.
6. Gothic Half-Up Twists
Gothic half-up twists strike the perfect balance between done and undone. She takes two front sections of hair, twists each one back away from the face, and pins them together at the back of the head with decorative bobby pins or a small barrette. The rest of the hair falls loose — she can curl it, straighten it, or leave it natural. This style suits almost every face shape and hair texture, making it one of the most versatile Halloween hairstyles for long hair. It works for witch, vampire, gothic bride, and dark fairy costumes alike. Because the twists frame the face, it also keeps makeup visible and camera-ready. Pro tip: twist the sections slightly upward before pinning to create natural lift at the crown without any teasing.
7. Boho Witch Messy Bun
The boho witch messy bun is effortlessly mystical and takes under five minutes. She gathers her hair into a high ponytail, twists it loosely, and wraps it into a bun, securing it with bobby pins while leaving face-framing strands loose. She then pulls gently at the bun to create that perfectly imperfect texture. This Halloween hairstyle for long hair is ideal for bohemian witch, fortune teller, and free-spirit costumes. It suits thick hair best, but women with fine hair can use a donut form or tease the ponytail first. Adding a few tiny braids or a crystal headpiece elevates it instantly. Pro tip: spray dry shampoo at the roots before styling — the added grip makes messy buns hold twice as long.
8. Vampire Bride Low Chignon
The vampire bride low chignon is dark romance at its finest. She sweeps her hair into a low ponytail at the nape, twists it into a smooth chignon, and pins it securely. A center part and ultra-smooth finish give it that bridal elegance, while a black veil, dark red flowers, or a tiara with faux blood drops push it firmly into Halloween territory. This style suits women with fine to medium long hair and flatters long or oval faces. It is perfect for vampire bride, ghost bride, and dark wedding costumes, and it survives a whole evening of dancing without drooping. Pro tip: anchor the chignon with a hair donut base for a fuller shape that stays put without a hundred pins.
9. Fairy Tale Rapunzel Braid
The Rapunzel braid is the ultimate fairy tale statement. She brushes her hair completely smooth, gathers it to one side or down the back, and weaves a classic three-strand or fishtail braid all the way to the ends. Weaving in small faux flowers, ivy garlands, or golden ribbon transforms a simple braid into a costume centerpiece. This Halloween hairstyle for long hair requires genuinely long hair — mid-back or longer — for the full effect. It suits princess, fairy tale, medieval maiden, and woodland nymph costumes. The braid also keeps hair contained and tangle-free all night. Pro tip: lightly mist each section with hairspray before braiding to keep the braid tight and frizz-free for hours.
10. Zombie Tousled Bedhead
Zombie tousled bedhead is the rare Halloween hairstyle for long hair that rewards imperfection. She backcombs sections at the crown and through the mid-lengths, then roughs up the texture with her fingers and sets it with strong-hold hairspray. A little temporary gray or white hair spray at the roots sells the undead look. This style works on any hair texture and length past the shoulders, and it suits zombie, ghost, and haunted asylum costumes perfectly. Because messiness is the goal, it is forgiving for beginners and takes less than ten minutes. Pro tip: flip the head upside down while applying hairspray for maximum gravity-defying volume.
11. Dark Fairy Loose Curls
Dark fairy loose curls combine softness with a sinister edge. She curls large sections with a wide-barrel iron, then brushes through gently to create loose, flowing curls rather than tight ringlets. A deep side part adds drama and mystery. Dark temporary color spray or colored clip-in extensions in purple, black, or deep blue push the look toward fantasy. This style suits heart and oval faces beautifully and works for dark fairy, evil enchantress, and forest spirit costumes. Long hair shows off the curl pattern best, especially in motion. Pro tip: let each curl cool completely in her palm before releasing — this sets the curl memory for all-night bounce.
12. Elvira-Inspired Voluminous Blowout
The Elvira-inspired voluminous blowout is pure horror-hostess glamour. She blow-dries her hair with a round brush, lifting at the roots for maximum height, then sets the top sections with hot rollers or Velcro rollers while the hair cools. After removing the rollers, she brushes through for that cascading, bombshell volume. This Halloween hairstyle for long hair suits thick, layered hair best and flatters round faces by adding height. It is the perfect match for an Elvira, vampire hostess, or retro horror costume. The silhouette reads instantly from across the room. Pro tip: tease only the under-layers at the crown and smooth the top layer over them — hidden volume with a polished finish.
13. Ghostly White Streaks
Ghostly white streaks turn any long hairstyle into a supernatural statement. She applies temporary white or silver hair spray, chalk, or clip-in streaks to a few face-framing sections, then styles her hair as usual — straight, wavy, or curled. The contrast against dark hair is striking and reads instantly as ghost, banshee, or haunted spirit. This works on every hair texture and suits anyone, since the streaks are removable and commitment-free. It pairs beautifully with pale makeup and dark lips. Pro tip: apply the white chalk to slightly damp sections and seal with hairspray — the color grips better and lasts through the whole night.
14. Spiderweb Braid
The spiderweb braid is an intricate showstopper that looks far harder than it is. She creates a Dutch braid starting at the crown, then weaves thin black or silver cord — or even string — through the braid in a crisscross pattern as she goes, mimicking a web. A small plastic spider clipped near the braid completes the effect. This Halloween hairstyle for long hair suits arachnid, witch, and dark fairy costumes, and it works best on hair that is at least mid-back length. It is a genuine conversation starter at any party. Pro tip: keep the braid slightly loose while weaving the cord — a tight braid makes threading nearly impossible.
15. Haunted Mansion Updo
The haunted mansion updo channels Victorian ghost elegance. She teases the crown for height, sweeps the hair up into a soft French twist or Gibson tuck, and allows a few tendrils to escape around the face. A cameo brooch, black feather, or small veil pinned into the style completes the haunted aristocrat look. This refined Halloween hairstyle for long hair suits medium to thick hair and flatters most face shapes. It is perfect for ghost, Victorian lady, haunted portrait, and dark period-drama costumes, and it photographs beautifully. Pro tip: insert bobby pins with the wavy side facing the scalp — they grip far better and stay hidden.
