Butterfly weft extensions are the quiet revolution in hair volume — ultra-thin PU-based wefts that lie flat against your scalp instead of stacking up like a bulky track. But not every butterfly weft is built the same. The differences come down to how much hair you actually get per pack, how wide the weft runs, and whether the base stays invisible when you pull your hair back. This guide cuts through the listing photos to show you which wefts hold up — and which leave you buying three packs to get one head of hair.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Some packs cover a full head on their own. Others need several wefts (strips of hair sewn onto a base) to avoid a thin result. So before you buy, match two numbers to your own hair density (how much hair you have per square inch): the gram weight (how much hair the pack holds) and the weft width (how wide each strip is). Reading those two numbers correctly is the first step to the right butterfly weft hair extensions.
Top Picks
How To Choose The Best Butterfly Weft Hair Extensions
Butterfly weft extensions are human hair strips with a thin, flexible PU base and a row of small holes down the centre. Those holes let a stylist thread micro-beads through, so the weft sits flat and invisible instead of stacked like a traditional clip-in track. That design is why they blend so well — but it’s also why the grams per pack figure matters more than any other number on the listing.
Gram weight per pack is the number that decides coverage
Look at a butterfly weft listing and you’ll see two numbers: length in inches and weight in grams. The grams figure tells you how much hair you actually get. A 50 g pack adds a little fullness; a 100 g pack covers more ground; a 120 g pack frequently fills a whole head. If you have thick or long natural hair, budget for extra packs upfront — one skinny bundle won’t blend.
Weft width and how many pieces come in the pack
A wide weft like a 31.5-inch strip can be cut down to fit your head exactly, giving you flexibility and less waste. Narrower wefts or multi-piece sets with smaller segments give you more control around the hairline and crown. Both approaches work — the key is whether the weft is cut-to-fit or pre-cut, and matching that to your installer’s preferred method.
PU base thickness and how flat the install sits
The PU base is the clear strip the hair is bonded to. Thinner PU means the weft lies flatter against the scalp and stays hidden when your hair is pulled up. But very thin PU can compromise durability. The best butterfly wefts balance invisibility with enough PU to hold the bead securely through a full wear cycle.
Heat tolerance and dye rules for real Remy hair
Real human hair can be curled and straightened, but the safe temperature varies by product — some caps sit lower than you’d guess. Always check the listed heat ceiling before you plug in your iron. Dyeing is also restricted: professional toning is usually acceptable, but bleaching generally isn’t recommended on these extensions.

Detailed Reviews
1. Youngsmile Balayage Clip in Hair Extensions 14 Inch
Our pick — 4.0+★ from 70+ verified ratings; the strongest balance of quality and price.
A 7-piece clip-in set with ash-brown-to-platinum balayage already painted in.
Clip-in fans get a shortcut here: one 120 g set across 7 pieces, which the 4.0+ star crowd treats as a serious volume upgrade. The warm ash-brown-to-platinum gradient is the whole pitch, and the strand work holds up — owners repeatedly describe the texture as excellent and the length as exactly what was advertised. As one buyer put it after buying two packs and fitting most of the pieces: “I bought 2 packs and have most of them in in the picture.”
Owners consistently praise the strand quality first, calling the texture excellent and the length exactly as advertised. Color matching is the honest wrinkle here, and it cuts both ways: some owners call it “perfection,” while others hit a mismatch. The blended ash-to-platinum tone is the hardest kind to nail across screens, so ordering a swatch or messaging the seller with a daylight photo is smart if your hair sits between shades.
The daily-wear reality is also worth planning for. Clip-ins add weight, and a full set of thick wefts can make the back of your head feel heavy by evening — that’s inherent to clip-ins, not a defect. The metal clips use silicone grips to hold without damaging your natural hair, and the pieces are heat-safe to 280°F for curling or straightening to match your own texture.
The strong points
- 120 g across 7 pieces — meaningfully more hair per set than the 50 g Anrosa pack
- Balayage color work means no salon appointment for the ombré look
- Heat-safe to 280°F, so you can curl or straighten to match your own hair
- Silicone grip clips designed to hold without slipping or damaging your strands
Where it needs care
- Color match is the most-discussed point and it divides buyers — swatch first if you’re between shades
- The curl drops faster than some would like; expect to re-set it through the day
- A full 7-piece set can feel heavy by evening — the cost of clip-in volume
Reach for this if: you want instant balayage color and real length without committing to a salon process.
Worth knowing: the color is the one variable — confirm your shade before you settle in, because a balance between ash and platinum is the trickiest match to nail online.
2. SUYYA Butterfly Weft Hair Extensions 14 Inch
A single 31.5-inch weft you trim yourself — enough width to wrap a whole head.
The flexible PU base with centre-hole placement is what earns SUYYA its place near the top. That design lets micro-beads sit hidden inside the hair line so nothing slips, and the weft lies flat with no bulky track showing through. One 31.5-inch strip means you can cut it to your exact head shape rather than wrestling with pre-cut pieces. Those who install these regularly describe the weft as soft, flat, and quick to fit — with the hair quality itself coming in for the most consistent praise.
One pack gives you a 14-inch length and a full 31.5-inch width, so you get the widest weft in this lineup — a clear margin over the 15.7-inch Anrosa strip. That width means less piecing together for a full head. But buyers report split results on thickness: some find it full top-to-bottom, others find it thin for the volume they hoped for. A pack includes two long pieces plus the beads and hook needle (a needle that pulls the bead and thread through your hair). Whether that covers your head depends on your own density. Short or fine hair tends to be the balance.
Install time is a real consideration. The wefts are less flexible than some, so the long back pieces work best positioned as back rows with smaller side sections trimmed to fit. Several wearers trim the long pieces for ponytail comfort. Once settled, the payoff is real: owners mention the hair stays put through daily wear, with one noting the hair held clean and tangle-free “At 10 days: no shedding, no tangles.”
Best install setup: treat this weft as a back-row foundation and cut it down for the sides — the 31.5-inch width gives you plenty of material to work with. The PU base (a polyurethane strip the hair is bonded to) is thin enough to stay hidden, and that is the whole reason bead installs look smooth.
The honest catch: for a full-volume result on thick hair, one pack may not be enough. Buyers who wanted real density often reach for a second pack, which adds to total spend. On fine or short hair, a single pack can go the distance.
Choose it when: you’re building a beaded install and want a wide, cut-to-fit weft that lies flat under the part.
Think twice if: your natural hair is thick and full — you’ll likely need more than a single pack to match your own density.
3. Anrosa Butterfly Weft Hair Extensions Human Hair 20 Inch 50G
Twenty inches of real Remy hair for anyone chasing length without the weight.
Anrosa trades mass for length. At 20 inches it runs a full 6 inches longer than the 14-inch Youngsmile set, yet weighs in at only 50 g — exactly the lightweight, flat weft that fine-haired wearers reach for. The ultra-thin PU double weft with centre-hole OVO design fixes with micro-beads, no glue or sewing, so removal is genuinely low-stress. The softness is what people keep coming back to: it feels natural, blends well, and the straight texture takes to styling easily.
What owners consistently note is the hair’s quality — soft, shine-bright, blendable with your own ends. The length is also the headline: 20 inches delivers a visible transformation, and the 15.7-inch weft width gives you a manageable strip that won’t overwhelm a finer head of hair. What you get in the box is practical too, with beads and a crochet hook included so you’re not hunting for install tools separately.
The trade-off you need to weigh: at 50 g, this is a volume top-up, not a full-head fixture. Most wearers discover they need multiple wefts to build real density — which pushes total cost up over time. There’s no printed instruction sheet in the pack either, so a first-timer will want to watch a beading tutorial before they start. The PU strip runs slightly thicker than some expect, though it hides under the top layers once installed.
Why it wins a spot
- 20 inches of length in a pack that weighs only 50 g — flat and light against the scalp
- Micro-bead centre-hole design needs no glue or sewing, and removes cleanly
- Straight texture straightens, curls, and washes without fighting you
- Beads and crochet hook included in the pack
The giving and taking
- 50 g alone is too thin for a full head — most need multiple wefts
- No printed install instructions included, so plan to watch a tutorial
- The PU strip is a touch thicker than you might expect, though it hides once covered
Pick it for: adding visible length and a gentle volume lift on fine or naturally thin hair.
Budget for: buying more than one weft if you want real fullness — a single 50 g pack is a starting piece, not a complete set.
4. Butterfly Weft Human Hair Extensions 16Inch
The pack that hands you the beads, the needle, and a shot at doing it yourself.
The cut-to-fit 31.5-inch weft is the engine here — that’s a full metre-plus of material you can trim to your own head shape, with a micro-bead hole weft built for glueless installs. You also get a starter kit in the box: a pack of micro-beads, a crochet/loop needle, two clips, and instructions. The 4.0+ star rating rests on the hair itself, with softness a close second. The 4.0+ star result reflects strong feedback on the hair itself, with softness close behind — the texture is genuinely smooth and real Remy through its length.
Real-world use tells a clearer story than the listing. Two packs on a fuller head gives proper density; one 100 g pack covers medium length and volume on fine hair. Wefts lie flat and conceal neatly even in a high ponytail, and with proper care the ends stay soft through a long stretch of wear. One recurring theme is shedding when brushing daily — present but manageable, and mirrored by a mixed aspect in the reviews. Silkier handling and a careful brush routine keep it in check.
Heat is capped at 320°F/160°C, and you’ll want a protectant under the iron. Professional colour toning is fine, but bleaching isn’t recommended — real Remy hair that’s been through a colour process doesn’t take kindly to a second round. As for the shade itself: the darker lowlight can read a touch chunky on some tones, and if you want the tone to soften you may need a professional eye on it.
What earns it a slot: the full DIY kit is the differentiator — beads, needle, and clips in the box means a first install is possible without a separate supplies run. And 100 g is a real step up from 50 g without the heft of a full 120 g set.
Straight talk: shedding during brushing is the honest caveat, and heat styling tops out at 320°F. Buy fine-to-medium and this weft performs; buy looking to match thick natural hair, and you may feel it comes up short.
Make it yours if: this is your first butterfly weft install and you want a kit that gets you going without extra shopping.
Pass it over if: you’re planning intense heat styling — 320°F is the ceiling here, so treat it lower than your natural hair’s iron setting.
5. MOTFIN Blonde Clip in Hair Extensions 22 ins
Twenty-two inches of blonde real hair for anyone tired of salon-length commitment.
The longest set on this list at 22 inches, and it’s the one buyers keep coming back to for value. Eight silicone-backed clips hold without slipping through a full day, and the double-weft construction keeps shedding low. Blonde is notoriously hard to match — that’s why the natural-appearance feedback carries weight here. The 4.0+ star result is the strongest overall rating in this lineup, and it’s driven by a combination of realistic tone and a hairline clip design that disappears into fine and straight hair.
The set survives repeated washes and heat styling without losing its finish, and the eight silicone-backed clips hold firm through a full day. The colour-match reviews read consistently well, and this is the pick most likely to actually match a blonde who’s been burned by bad colour matches before. Curl retention is solid too — soft waves hold through the day without going limp.
The honest caveat is thickness. 80–120 g on the double weft is enough for a natural lift, but if you want big, voluminous waves you’ll need two or three packs. Several wearers describe it as “very thin” for that reason, and the manufacturer’s own advice points to 2–3 packs for a full head. The weft design itself handles fine hair beautifully; it’s the density you need to plan around.
Why it ranks high
- 22 inches — the longest length here, and enough to make a visible difference
- Natural blonde tone that blends with real hair rather than sitting on top of it
- Holds curls well and survives multiple washes plus heat styling
- Eight silicone-backed clips stay put without tugging
What to budget around
- Full, voluminous results need two or three packs — one set alone is a thickness lift
- Blonde can be tricky to match if your tone sits between shades
- Heat styling ceiling sits under 250°F, so keep your iron low
Lean toward this if: you’re blonde, want length fast, and prefer a clip-in you can remove the same night.
Go in clear-eyed on: density — plan for multiple packs if your goal is dramatic volume rather than a subtle fullness boost.
6. Full Shine Butterfly Weft Hair Extensions 22 Inch
A double-sided PU weft built for airflow on one side and a secure fit on the other.
Full Shine’s angle is the double-sided build: strong PU facing down for grip, the genius weft face up for airflow, all in an ultra-thin design that spreads pressure evenly — a thoughtful detail for fine hair. At 22 inches and 100 g per pack, it gives you a long run of hair with enough density for a proper lift. The remy processing is aimed at that soft, healthy movement that copies your own hair rather than sitting stiff against it, and it installs clamp-free with micro-beads.
But here’s the part you need to hear: the feedback is mixed, and the 3.0+ star overall reflects that honestly. Some buyers are devoted — hairstylists in particular have noted it suits clients who won’t spend salon money. Others find it runs thin and reports of it not lasting beyond a month show up. Curl holding is another sticking point: some wearers find it drops within an hour or two regardless of product. If you want a weft that takes a curl and keeps it, this one asks you to lower expectations.
The upsides are real for the right buyer. Jet black is hard to fake without looking flat — this one reads deep and rich, and remy processing gives it natural swing. Care is straightforward: mild shampoo, warm water, air-dry, and a loose ponytail before bed. If your hair is coarse and dark and you want length without a colour correction, this weft makes the most of that narrow lane. If your hair is fine, the caution is to buy extra packs for density and expect the finer strands to demand gentle handling.
Who it clicks with: jet-black-haired wearers who want length and don’t need the weft to do heavy lifting on volume. The double-sided build and breathable face are genuinely good details for a warm head or fine scalp.
The real trade-off: hair quality is the most-discussed trait and it’s a mixed bag — some love it, some find it thin and short-lived. Go in knowing this is a value play on a black shade, not a high-end investment piece.
Right for: dark-haired wearers chasing a deep jet-black match with a breathable, double-sided weft.
Not for: curl chasers who need hold through a full day, or anyone expecting a single weft to build dramatic density.
7. FANCEE Butterfly OVO Weft Hair Extensions 18 Inch
Seven wefts in graduated widths — engineered for fine, limp hair that needs scaffolding.
FANCEE is the most customisable set here: one 6-inch weft, two 4.5-inch, two 3-inch, and two 1.5-inch pieces you can layer and scatter to mimic your own hair’s fall. The double-weft OVO build gives volume without the bulk, and the invisible weft lies flat so the hairline reads like your own hair growing. It’s built squarely for fine, limp hair that lacks body — and owners with exactly that concern describe the hair as soft, lightweight, and easy to maintain across multiple client installations.
That quality backs the 4.0+ star rating: it takes toner, vivid colour, and curl like real hair. It takes toner, vibrant colour, and curl like real hair, installs faster than a sewn-in, and sheds minimally with no tangling. For fine-haired wearers the multi-piece design is genuinely useful — you can cut the wefts vertically to scatter them and hide the joins. The 18-inch length sits comfortably between the shorter wefts and the longer 22-inch sets, giving you noticeable length without overwhelming a smaller head.
Where it can disappoint: the realism is the mixed spot. Some find it reads slightly plastic, and a few report tangling and itchiness. The wefts are more heat-sensitive than natural hair, and at roughly 100 g the set runs thin for anyone chasing thick results. If your hair is coarse or full, this set is fighting your density rather than complementing it — it’s a fine-hair tool, not a universal one.
What it delivers
- 7 graduated wefts let you build a natural, layered fall around the hairline
- Double-weft OVO design adds body without the bulk
- Blonde takes toner, vivid colour, and curl like natural hair
- Faster to install than a sewn-in weave, with little shedding
Where it needs care
- Realism is the mixed trait — some find the texture reads a little synthetic
- Roughly 100 g per set runs thin for thick-hair volume goals
- More heat-sensitive than natural hair, so keep the iron low
Hand it to: fine or thinning hair that needs a discreet volume lift with a layered, undetectable finish.
Leave it be if: you have coarse, thick hair — you’d be fighting the weft’s density limits, and a heftier set will serve you better.
Know the Specs
Gram weight per pack
Grams tell you how much actual hair you’re getting. A 50 g pack is a volume top-up for a thin-haired wearer; a 100 g pack covers more; a 120 g set can cover a whole head. If your natural hair is thick or long, budget for two packs — under-ordering is the most common buyer regret with butterfly wefts.
Weft width and cut-to-fit design
A 31.5-inch weft can be trimmed to your exact head shape, giving you flexibility and less waste. Narrower 15.7-inch wefts or multi-piece sets with graduated segments give more control around the hairline. Match the width to your install method — wide for back rows, narrow for the sides.
PU base thickness and invisibility
The PU base is what holds the weft flat against your scalp. Thinner PU gives a more smooth look but can shorten how long it lasts. Thicker PU holds up better through repeated wear cycles but may show more bulk under very fine hair. Weigh the two against your hair type.
Heat tolerance and dye limits
These are real human hair products, so they take heat styling — but the ceiling varies by product. Always check the listed limit before you pick up your iron. Bleaching isn’t recommended on colour-processed extensions; professional toning is usually fine.

The Bottom Line
For most buyers, the butterfly weft hair extensions winner is the Youngsmile Balayage Clip-In. It gives you 120 g of real Remy hair (human hair with the cuticle kept aligned) in 7 pieces, with balayage colour (hand-painted highlights) already built in. That means 120 g of length and volume with the ombré already done. If you want a wide, cut-to-fit weft for a beaded install, the SUYYA Butterfly Weft gives you a full 31.5 inches of width to trim to your own head. And for fine or limp hair that needs an invisible volume lift, reach for the FANCEE Butterfly Weft with its graduated 7-piece set.
The MOTFIN blonde clip-in carries the lineup’s highest rating at 4.0+ stars across 160+ ratings, with a natural blonde tone that blends rather than sits on top. Whichever you choose, confirm your gram weight first: it’s the single number that decides whether you walk out with full hair or a thin top-up.
