Most extension education focuses on three weft types: hand-tied, machine, and genius weft. Butterfly wefts exist in a category that most stylists have encountered but few have had properly explained — what makes the construction different, who the client is, and when to choose butterfly over the alternatives.
This guide covers all of it. Construction specs, installation method, comparison against other weft types, ideal client profile, and the FAQ section that answers every question your clients will ask before booking.
KmXtend produces butterfly wefts as part of our professional extension range. Like our Genius Weft extensions, butterfly wefts are a stylist-channel product — designed for professional installation, not DIY application.
What Is a Butterfly Weft? The Construction Explained
A butterfly weft gets its name from its physical structure. Unlike a standard single-track weft — where all hair strands are secured to a single flat spine — a butterfly weft uses a folded double-layer construction. When the weft is held up and gently opened, the two layers spread apart at the base, creating a silhouette that resembles a butterfly wing.
That structural difference is not cosmetic. It is functional.
The split base means the attachment points are distributed across a broader area of the scalp rather than concentrated along a single track. The result is two things stylists care about: more volume output per row, and a different weight distribution model compared to single-track wefts.
Key construction specs for KmXtend Butterfly Wefts:
- Construction: folded double-layer weft with split base
- Hair type: 100% Remy human hair, cuticle-aligned
- Available length: 18- 24 inches
- Installation method: beaded row or sew-in
- Maintenance interval: move-up every 6–8 weeks
- Longevity: 9–12 months with proper care
How Butterfly Wefts Are Installed
Butterfly weft installation follows the same foundational technique as other beaded-row weft methods, with one important handling difference: the weft must be opened and positioned correctly before securing.
Here is the process in sequence:
1. Prepare the beaded row
Section the hair and create the beaded row at the desired placement height, exactly as you would for hand-tied or genius weft installation. The row preparation is identical regardless of weft type.
2. Unfold the weft
Butterfly wefts are typically stored folded. Before installation, gently open the weft along its spine to reveal the split base. The two layers should separate cleanly. Do not pull or force the fold — handle the weft from the edges to avoid distorting the base.
3. Position and secure
Position the opened weft along the beaded row so the split base sits evenly on either side of the row. Secure using your preferred attachment method. Pull the hair through the holes and attach every two strands with a bead. On the heads, secure the last single end with a bead. The split base should fan slightly — this is correct and intentional. It is what creates the volume effect and distributes the attachment load.
4. Blend and cut in
Once secured, blend and cut the weft into the client's natural hair. Because butterfly wefts deliver more density per row, cutting-in is an important step for a natural result — especially on fine-haired clients where over-density creates detection risk.
STYLIST NOTE: First-time butterfly weft installs typically take slightly longer than a standard weft install as you calibrate positioning with the split base. By the second or third install, the technique becomes efficient and the volume payoff per row is significant.
Butterfly Weft vs Genius Weft: Which Is Right for Your Client?
KmXtend produces both butterfly wefts and Genius Wefts. They are different tools for different outcomes — not competing products. Understanding when to use each is the mark of an experienced extension stylist.
| Factor | KmXtend Genius Weft | KmXtend Butterfly Weft |
|---|---|---|
| Weft thickness / flatness | 0.5–0.7mm — industry's flattest | Thicker due to double-layer fold |
| Volume output per row | High — dense single track | Very high — double-layer delivers more per row |
| Cut flexibility | Cut anywhere, marked every 1.5 inches | Cuttable, with care at weft edge |
| Best hair type | Fine to medium — maximum undetectable result | Medium to thick — volume impact with fewer rows |
| Scalp tension model | Distributed along single flat spine | Distributed across split base — broader footprint |
| Packs for full install | 3–4 packs typical | 2–3 packs typical |
| Longevity | 12–24 months | 9–12 months |
| Ideal client | Fine hair, scalp sensitivity, maximum discretion | Medium-thick hair, dramatic volume, fewer rows desired |
DECISION RULE: If your client's primary goal is undetectable and their hair is fine, choose Genius Weft. If your client wants maximum volume impact and has the hair density to support it, butterfly weft delivers more per row with a faster install.
Butterfly Weft vs Hand-Tied Weft
The comparison stylists ask about most often is butterfly weft versus hand-tied — because hand-tied has been the premium benchmark for fine hair for years, and butterfly weft is newer to many practices.
The key differences:
- Cuttability: Butterfly wefts can be cut. Hand-tied wefts cannot — cutting causes unraveling. This gives butterfly wefts a meaningful installation flexibility advantage.
- Volume output: Butterfly wefts deliver more volume per row due to the double-layer construction. Hand-tied wefts are intentionally lighter and lower-density, which is why stylists use more of them for dimensional color layering.
- Longevity: All KmXtend wefts havea longevity advantage for clients focused on multiple wear cycles typically 12 months with proper care.
- Installation time: Butterfly weft installation is much faster than a sew in weft install.
The Ideal Client Profile for Butterfly Wefts
Not every client is the right fit for butterfly wefts. Here is the profile where they consistently outperform alternatives:
Best suited for:
- Clients with fine to medium hair who want additional volume and length
- Clients who want maximum fullness with fewer installation rows
- Clients who have previously worn extensions and understand maintenance requirements
- Clients who are not primarily concerned with the absolute flattest possible weft (that remains Genius Weft territory)
- Clients with active lifestyles who prefer fewer rows to maintain
- Clients with busy schedules and can't sit for hours for weft installation
Less suited for:
- Clients with thicker hair should stick with machine or multiple rows of genius wefts
- Clients who wear their hair in sleek updos daily — the thicker weft base is less forgiving in very smooth, tight styles
Butterfly Weft Care: What Clients Need to Know
Butterfly wefts are a professional-grade product that rewards clients who commit to a proper care routine. Share these guidelines at every consultation:
Washing: Wash hair every 5–7 days maximum. Use a sulfate-free, extension-safe shampoo applied from root to tip in downward strokes — never circular scrubbing at the weft attachment points. Conditioner from mid-length to ends only.
Brushing: Brush twice daily with a loop brush or boar hair-bristle extension brush. Always start at the ends and work upward. Hold the hair just below the weft when brushing near the roots to avoid pulling on the attachment points.
Heat styling: Heat tools are safe to use on Remy human hair extensions. Always apply a heat protectant before styling. Avoid directing heat directly onto the weft attachment points — work on the hair length, not the roots.
Sleeping: Braid or loosely plait hair before sleeping to prevent matting at the weft roots. A silk pillowcase reduces friction on both the extensions and the natural hair.
Move-ups: Schedule move-up appointments every 6–8 weeks. Delaying past 6-8 weeks increases the risk of matting at the grow-out and makes the move-up appointment significantly more time-intensive and tension on the row, causing risk for alopecia.
Why KmXtend Butterfly Wefts
KmXtend Butterfly Wefts are made from 100% Remy human hair with cuticles intact and aligned in the same direction throughout the weft. Cuticle alignment is what determines whether extensions tangle and matt over weeks of wear — it is not a cosmetic quality, it is a structural one.
Our butterfly wefts are available in 18 and 22-inch lengths in the same color range as our Genius Weft collection, allowing stylists to mix weft types within a single install for customized density and volume distribution. 24 inches will be available soon on the website.
Both butterfly wefts and our KmX Genius Wefts are available through the KmXtend professional store. If you are a licensed stylist and want to explore our full range and wholesale pricing, you can apply for a PRO account here.

Frequently Asked Questions: Butterfly Weft Extensions
What are butterfly weft hair extensions?
Butterfly wefts are a professional weft extension format constructed with a folded double-layer spine that creates a butterfly-wing shape when unfolded. The folded structure produces an ultra-flat, split base that distributes attachment points across a wider area than a standard single-track weft — reducing concentrated scalp tension while adding significant volume from a single row.
What is the difference between butterfly wefts and genius wefts?
Genius wefts are a single-track weft with an ultra-thin spine (0.5–0.7mm) optimized for flatness and cut-anywhere flexibility. Butterfly wefts use a folded double-layer construction that delivers more volume per row and a split base that disperses tension differently. Genius wefts are the better choice when maximum flatness and customization are priorities. Butterfly wefts are ideal when a stylist needs significant volume impact from fewer rows.
Are butterfly wefts good for fine hair?
Butterfly wefts work well for fine hair when installed correctly by an experienced stylist. The split base distributes weight across a broader attachment area than a standard weft, reducing concentrated scalp tension. However, because butterfly wefts deliver more volume per row, stylists should carefully calibrate the number of packs used — too much density on fine hair can create detection risk. For the most undetectable result on fine hair, KmXtend Genius Wefts at 0.5–0.7mm remain the flattest option.
How are butterfly wefts installed?
Butterfly wefts are installed using a pull through method secured with beads. No sewing is required. The weft is unfolded to reveal its split base, then positioned and secured along a prepared beaded row. The folded construction means the weft sits differently than a flat single-track weft — the split base fans slightly outward at the attachment point, which is what creates the volume effect. Installation requires a stylist trained in weft extensions.
How long do butterfly wefts last?
With proper care and regular move-up appointments every 6–8 weeks, butterfly wefts typically last 9–12 months. Longevity depends on the quality of the hair, the skill of the installation, and the client's maintenance routine — including use of sulfate-free shampoo, regular brushing with a loop brush, and avoiding excessive heat at the weft attachment points.
Can butterfly wefts be cut?
Yes, butterfly wefts can be cut to length. Unlike hand-tied wefts — which unravel if cut — butterfly wefts have a structured construction that tolerates trimming. Cuts should be made carefully to preserve the integrity of the weft edge. This is different from KmXtend Genius Wefts, which are specifically engineered for cut-anywhere flexibility with marked cut points every 1.5 inches.
How many butterfly weft packs do I need for a full head?
Most full installs require 2–3 packs of butterfly wefts, depending on the client's natural hair density and desired volume. Clients with thinner hair typically need 2 packs; those with medium-to-thick hair seeking dramatic volume may need 3. Because butterfly wefts deliver more volume per row than a standard single-track weft, fewer packs are required compared to some other weft methods. If you're looking for thickness only, not length, 1 pack may be all that is required (50 grams).
Are butterfly wefts the same as double-drawn wefts?
Double-drawn refers to a hair quality specification — it means short hairs have been removed so the weft is full from root to tip, rather than tapered at the ends. Butterfly weft refers to a weft construction type — the folded double-layer spine format. Our butterfly weft is double-drawn remy , cuticle aligned hair.
KmXtend Butterfly Wefts use Remy cuticle-aligned hair for consistent quality across the full length of the weft.
