Butterfly weft hair extensions have changed the game for anyone who wants added length and volume without the heavy, stiff feel of traditional tape-ins or the commitment of a full sew-in. The genius of this design lies in its double-layered construction — a hand-tied top layer that mimics scalp growth paired with a perforated PU base that lets your natural hair thread through and lock in place with tiny micro beads. The result is a flat, breathable weft that moves with your head and stays hidden even when you toss your hair up.
I’m Min — the co-founder and writer behind Gadgets Feed. I’ve combed through real customer experiences and technical specs across seven top butterfly weft hair extension sets, weighing factors like weight per pack (80g vs 100g vs 120g), length options, color accuracy, and the specific hole spacing that determines how invisible each weft sits on the scalp.
Whether you need a full head of volume or targeted fill-in for thin spots, this guide helps you find the right best butterfly weft hair extensions for your hair type, skill level, and desired look.
How To Choose The Best Butterfly Weft Hair Extensions
Not all butterfly wefts are built the same. The weight, length, hole design, and hair grade all affect how the final set looks and how long it lasts. Here are the critical factors to consider before buying.
Weight per Pack and Full Head Coverage
Butterfly wefts are sold by weight — typically 80g, 100g, or 120g per pack. An 80g weft works best for adding light volume or filling in specific sections, while 100g is the standard for a full-head install. The 120g packs deliver thicker density and are ideal if you have naturally thick hair or want dramatic volume. Most users need between one and three packs depending on their starting density and desired result.
Hole Spacing and PU Layer Quality
The perforations in the PU base determine how flat and invisible the weft sits. Premium options space holes about 1 cm apart with a 2 mm diameter and place them on the side of the weft rather than the center — this reduces scalp pressure and prevents bumpiness. A well-designed PU layer also improves airflow so the weft stays lightweight and doesn’t trap heat against your scalp.
Hair Grade: Remy vs Standard Human Hair
Remy human hair has all cuticles aligned in one direction, which prevents tangling and keeps the hair shiny after multiple washes. Lower-grade wefts may shed excessively or turn brittle after the first shampoo. Look for explicit “Remy” labeling and check customer reviews for feedback on how the hair holds up after washing and heat styling.

In‑Depth Reviews
1. KRN Butterfly Weft Hair Extensions
The KRN Butterfly Weft delivers that rare combination of softness, natural luster, and a structure that actually stays flat against the scalp. Made from 100% Remy human hair, the 100g pack at 16 inches provides enough density for a full head without feeling heavy. The double-layered Genius Weft design uses hand-tied holes that allow you to thread strands through and secure them with micro beads — no glue, no sewing, no tension on your follicles.
Customer reviews consistently praise the natural color blend and the lightweight feel. One experienced user noted it ranks in their top two overall weft brands, comparing favorably against much pricier salon options. Another called the texture soft and the blend seamless even in bathroom lighting. The weft is also cuttable without fraying, which lets you customize the width to fit your specific hairline or fill in sparse patches without waste.
Installation requires patience and ideally a second pair of hands, but the payoff is a look that moves like natural hair. The itch-free adhesive and tension-free design reduce stress on sensitive scalps, making this a strong choice for anyone concerned about damage. The main trade-off is longevity — some users report it doesn’t last as long as premium alternatives, but for the quality per dollar, the KRN weft is tough to beat.
Why it’s great
- 100% Remy human hair with natural luster and soft feel
- Lightweight double-layered design lies flat and invisible
- Cuttable edges prevent fraying and allow custom width
Good to know
- Shorter lifespan compared to high-end wefts — expect 6–8 weeks with good care
- Installation fiddly — best done with a friend or professional
2. YoungSee Butterfly Weft Platinum Blonde
The YoungSee Platinum Blonde butterfly weft is built around a double-layer design and an ultra-thin PU base that keeps the weft invisible even when you pull your hair back. At 80g and 16 inches, it’s lighter than the 100g standard, making it a smart choice for adding delicate volume to fine or thin hair without overwhelming your natural strands. The micro-bead fixation method reduces pulling force, which is especially important for fragile hair types.
Professional hairstylists in the reviews confirm the quality — one licensed stylist ordered three packs in different colors (dark brown and two balayage shades) with varying lengths from 18 to 24 inches to create a layered, highlighted look. They noted minimal shedding after two washes and rated the texture better than other Amazon and LA brand extensions. The color accuracy for the ombre blonde shades also gets high marks, with users saying the blend is not striped and blends naturally with their own color.
The 80g weight means you’ll likely need two packs for a full head, but that also gives you flexibility to mix lengths for a more natural gradient. The weft is heat-styleable and holds curls well after blow-drying. The only feedback from experienced users is a wish for the “genius weft” hole configuration seen on some competing brands — the YoungSee holes work fine but could be slightly more forgiving during threading.
Why it’s great
- Skin-friendly micro-bead fixation protects fine or thin hair
- Professional-grade Remy hair with minimal shedding after multiple washes
- Available in multi-packs for mixed-length layered looks
Good to know
- 80g per pack — budget for two packs if you need full head coverage
- Hole design slightly less refined than premium competitors
3. YoungSee 100g Dark Brown Butterfly Weft
The YoungSee 100g Dark Brown weft is essentially the thicker, longer sibling of the 80g version. At 18 inches with a full 100g weight, this pack delivers enough density and length for a complete full-head install in a single purchase. The double-layer weft and ultra-thin PU base sit flat on the scalp, and the evenly distributed holes reduce pressure across the entire weft line — a detail that matters when you wear extensions for 8+ hours at a time.
Reviews from a professional hairstylist specifically call out the ease of self-installation and the ability to double wefts for extra thickness. The dark brown shade (Color #2) is a true, rich brown without red undertones, which helps it blend naturally with most medium to dark brown natural hair. Users report that the hair washes and blow-dries well, and that shedding is minimal even after the second wash — a common failure point for budget wefts that lose 20-30% of their density early on.
The Remy processing ensures all cuticles run in the same direction, which prevents the mid-length tangling that plagues lower-grade hair. The weft is cuttable without shedding at the cut line, and heat tools can be used to switch between straight and curly styles. The only real limitation is the color range — if you need a specific balayage or highlighted shade, you may need to look at the YoungSee highlighted options instead.
Why it’s great
- Full 100g weight at 18 inches — one pack covers most full-head installs
- Remy cuticle alignment prevents tangling and mid-length frizz
- Cuttable edges that don’t shed or fray after trimming
Good to know
- Limited to solid dark brown — no balayage or highlight options in this SKU
- Some users prefer side-hole placement for reduced scalp pressure
4. YoungSee Balayage 100g Butterfly Weft
The YoungSee Balayage Butterfly Weft brings the same double-layer construction and 100g density as the solid dark brown version, but with a chocolate brown to light blonde ombre transition that mimics a salon-painted balayage. The seamless color gradient runs naturally through the weft, which means no harsh lines when you blend it with your own highlighted or ombre hair. The PU base is thin enough to stay invisible, and the holes are evenly spaced for balanced pressure distribution.
A licensed cosmetologist reported using these in a layered install with three different lengths (18, 22, and 24 inches) to build a natural-looking, highlighted volume. They noted the wefts were easy to dye darker when needed and that shedding was minimal. Customers with fine natural hair specifically call out the thickness — the balayage weft is dense enough that some users cut a portion off to create a second halo piece with extra wires, effectively getting two applications from one pack.
Color accuracy is a strong suit here. The ash blonde ombre is not striped, and the transition avoids the “skunk stripe” look that plagues cheaper highlighted extensions. The hair holds curl well and remains soft after washing. The main consideration is the 18-inch length — if you need a longer balayage look, you’ll want to check the 22 or 24-inch options from the same brand, though those are sold separately.
Why it’s great
- Natural balayage gradient with no harsh color lines
- Dense 100g weft — thick enough to split for two applications on fine hair
- Remy human hair stays soft and holds curl across multiple washes
Good to know
- Limited to 18-inch length in this SKU — longer balayage wefts sold separately
- Color match depends on your exact natural shade — order a color ring if unsure
5. Ugeat 18 Inch Blonde Butterfly Weft
The Ugeat Butterfly Weft stands out for its refined hole engineering. The perforations are spaced 1 cm apart with a 2 mm diameter and positioned on the side of the PU weft rather than the center — a detail that reduces scalp pressure significantly compared to central-hole designs. One side uses hand-tied imitation for invisibility, while the other side uses PU for airflow and heat reduction, creating what the brand calls a “no-sensation” wearing experience.
Customers consistently describe the hair as thick, soft, and free of split ends out of the pack. The color accuracy on the #60A platinum blonde is generally good, though one reviewer noted a slight yellow-pink tint that didn’t match their ash white blonde hair — something to keep in mind if you’re a cool-toned platinum. The weft also includes a complete installation kit with a hook needle and micro rings, so you don’t need to buy extra tools.
One detailed review from a long-term user said the 20-inch, 100g weft felt thin initially but fluffed up significantly after the first wash, then lasted 8-9 weeks with minimal shedding and tangling. That kind of durability is rare in this price segment. The flexible cutting design means trimmed edges stay intact without fraying. The main caveat is that if your hair is a true cool ash blonde, double-check the tone before purchasing — the #60 shade leans slightly warm.
Why it’s great
- Side-positioned holes (1 cm apart) reduce scalp pressure noticeably
- Complete kit includes hook needle and micro rings — no extra purchases
- 8-9 week lifespan with minimal shedding and good curl retention
Good to know
- #60A platinum blonde may have slight warm undertones — not true ash white
- Weft feels thin initially but fluffs after first wash
6. Ubetta Balayage 120g Butterfly Weft
The Ubetta Butterfly Weft is the heaviest option at 120g with a 22-inch length, making it the go-to pick for anyone who wants serious length and density from a single pack. The double-layered PU construction (hand-tied upper layer plus soft PU bottom) lays flat and blends seamlessly with natural hair. The brand claims “no one can find it even on a windy day,” and the micro-bead installation keeps the weft secure without glue or sewing.
A licensed cosmetologist reviewed these as thick, soft, and minimal in shedding, noting they were easy to dye darker and produced great results on a pixie cut client. Another user used them for their wedding day and reported the hair was easy to work with and curled well. However, there are mixed reviews about hair quality after washing — one reviewer said the texture degraded and became brittle after the first sulfate-free wash, suspecting bleaching damage during processing.
The pack comes with 50-100 micro rings, which is enough for a full install. Ubetta recommends 1 pack for thick natural hair and 2 packs for very thin natural hair, which is the opposite of most brands — likely because the 120g density gives you more coverage per pack. The balayage color transitions between ash brown and blonde highlights, though the exact shade match can vary. If you’re risk-averse about texture post-wash, test a single pack before committing to multiple.
Why it’s great
- 120g density at 22 inches — thickest and longest option in this guide
- One pack may be enough even for naturally thick hair
- Complete installation kit with 50-100 micro rings included
Good to know
- Mixed reviews on post-wash texture — some report brittleness after first shampoo
- Color accuracy can vary between batches; order a sample if possible
7. YoungSee Light Brown Highlight Butterfly Weft
The YoungSee Light Brown Highlight weft combines the trusted 100g, 18-inch construction with a multi-tone color blend that mixes light brown with platinum blonde highlights. This creates a natural dimension that mimics sun-kissed hair, and the double-layer PU base keeps the weft invisible even under bright lighting. The evenly distributed holes reduce pressure, and the micro-bead fixation works well for both new and experienced users.
A professional hairstylist reported layering these with solid dark brown and balayage YoungSee wefts in different lengths (18, 22, and 24 inches) to create a full, salon-quality look. The hair blended naturally, washed well, and showed minimal shedding after two washes. Customers with fine hair specifically appreciate that the weft doesn’t feel heavy or pull on the scalp — the thin PU base and distributed hole pattern distribute weight evenly across the weft line.
The highlight blend is subtle enough that it doesn’t look striped or unnatural, but dramatic enough to add visible dimension to solid-color natural hair. The Remy processing ensures the hair stays soft and tangle-resistant even with regular heat styling. If you’re aiming for a natural highlighted look with medium density, this is the most straightforward path — one 100g pack delivers enough coverage for a full head on average thickness hair.
Why it’s great
- Multi-tone highlight blend looks natural and not striped
- Full 100g coverage — one pack suits most full-head installs
- Remy human hair stays soft and tangle-free across washes
Good to know
- Color blend is subtle — not ideal if you want bold, chunky highlights
- 18 inches is moderate length; longer options not available in this SKU
