Weft hair is one of the most versatile and widely used forms of hair extensions, favored by both salons and individual customers for its durability and natural blend. But if you’re new to the term, it can be confusing to understand exactly what a “weft” is, how it differs from other extension methods, and which type is right for your hair goals. This guide covers everything you need to know about weft hair — from the different types available to how it’s installed and maintained.
What Is Weft Hair?
Weft hair refers to strands of hair that are sewn or bonded together along a thin strip, called a “track” or “weft,” rather than being attached individually. This strip can then be sewn, glued, or clipped into your natural hair, depending on the installation method used. Because the hair is pre-assembled into a continuous strip, wefts allow stylists to cover larger sections of hair quickly, making them a popular choice for both full-head transformations and targeted volume additions.
Types of Weft Hair
Machine Weft
Machine wefts are created using a sewing machine to bind strands of hair together along a straight, flat track. This is the most common and affordable type of weft, offering a durable, flat foundation that works well for both sew-in and clip-in applications.
Hand-Tied Weft
Hand-tied wefts are hand-sewn strand by strand, resulting in a much thinner, flatter track compared to machine wefts. This makes them virtually undetectable when installed, ideal for clients seeking the most natural, seamless blend possible — though they typically come at a higher price point due to the labor involved.
Genius Weft
Genius wefts use a unique weaving technique that eliminates the bulky track entirely, allowing the extensions to lay completely flat against the scalp. This type is especially popular for tape-in style applications and for clients with fine or thinning hair who need a lightweight, discreet solution.
Common Installation Methods for Weft Hair
- Sew-In (Track and Sew): Natural hair is braided into cornrows, and the weft is sewn directly onto the braid using a needle and thread. This method is durable and long-lasting but requires professional application.
- Glue-In (Bonding): The weft track is bonded to natural hair using a specialized adhesive, offering a quicker installation without the need for braiding.
- Clip-In: Small clips are attached directly to the weft track, allowing for a temporary, no-commitment installation that can be done at home. This is the same method used in our clip-in hair extensions collection.
- Tape-In Style Weft: Genius or thin wefts can be taped in sections similar to traditional tape-in extensions, combining the durability of a weft with the ease of tape application.
How to Install Sew-In Weft Hair Step by Step
- Section and braid the natural hair into flat cornrows, starting from the nape and working upward.
- Thread a curved needle with matching thread and secure the starting point at the edge of the braid.
- Sew the weft track along the braid using small, even stitches, keeping tension consistent to avoid discomfort.
- Continue layering wefts upward, leaving a small section of natural hair at the top to blend and conceal the tracks.
- Cut and style the extensions to blend seamlessly with your natural hair length and texture.
Weft Hair Quality: Why It Matters
Regardless of installation method, the quality of the hair used in the weft has the biggest impact on how natural and long-lasting the final result looks. Wefts made from genuine Remy hair resist tangling and matting far better than non-Remy alternatives, and Virgin Vietnamese hair wefts offer the added benefit of being fully colorable and stylable without prior chemical processing limiting your options.
Single Drawn vs Double Drawn Wefts
Weft hair is available in both single drawn and double drawn options. Single drawn wefts create a more natural, tapered look at the ends, while double drawn wefts offer thicker, fuller volume from top to bottom — making them a popular choice for clients wanting maximum density. Our weft hair collection offers both options depending on the look you’re going for.
How Long Does Weft Hair Last?
A sew-in weft installation typically needs to be redone every 6 to 8 weeks as natural hair grows out, but the wefts themselves — if made from high-quality Virgin or Remy hair — can be reused across multiple installations for a year or more.

Weft Hair for Salons and Wholesale Buyers
Weft hair remains one of the most requested products among salons and resellers due to its versatility across multiple installation methods and its ability to serve a wide range of client needs — from subtle volume additions to full-head transformations. For those building a wholesale hair extensions business, sourcing consistent, high-quality wefts directly from a trusted Vietnamese hair factory ensures reliable quality across every order.
Frequently Asked Questions
What is the difference between weft hair and clip-in extensions?
Clip-in extensions are a type of weft hair with clips already attached for temporary, at-home installation. All clip-ins use weft technology, but not all wefts are designed for clip-in use — many are intended for sew-in or glue-in application instead.
Can weft hair be reused?
Yes, high-quality weft hair made from Remy or Virgin hair can typically be reused for multiple installations, provided it’s removed carefully and stored properly between uses.
Which type of weft is best for beginners?
Clip-in wefts are the easiest for beginners since they require no professional installation and can be applied and removed in minutes. For a more permanent solution, machine wefts installed via sew-in are a durable, cost-effective starting point.
Conclusion
Weft hair remains one of the most flexible and widely used forms of hair extensions, suitable for everything from quick, temporary styling to long-term, professionally installed transformations. Explore our weft hair collection to find the right type and quality for your next installation.
