Genius Weft

China Professional Genius Weft Manufacturer

Lum Hair is a professional manufacturer of hair extensions in China and supplier of Genius Weft Extensions. Genius Weft is made from soft, smooth, long-lasting top cuticle Remy hair, becoming customers' favorite extensions. It is the flattest and thinnest extension on the market, a finished weft after a specially adjusted machine. It enjoys great popularity among European countries, Australia, New Zealand, and the USA. According to stylists’ reports, genius wefts will make up 50% of newly installed high-end extensions in 2025.

Lum Hair Genius Weft combines the advantages of machine weft and hand-tied weft but is superior to both: it has machine hair weft strength and durability and is flatter and more flexible than a traditional hand-tied weft. It is only 0.4 to 0.7mm thickness and also can be cut as per customers' wants without shedding. Each weft provides the thinnest top for an invisible effect, and no returned hair ensures supreme comfort and durability. Because it is so flat, it lays flush against the scalp for a completely invisible install.

Structure & Installation Comparison (Genius Weft vs. Butterfly Weft)

Aspect Genius Weft Butterfly Weft
Core Structure

1. Features an ultra-thin, flexible weft crafted with full cuticle-aligned human hair.

2. When produced correctly, the weft can be trimmed at random and shedding is completely eliminated.

3. It works seamlessly for both short and long hair extension applications.

1. An advanced evolution of the Genius Weft, constructed by linking two Genius Weft pieces via a central opening with hole—enabling it to “spread” like butterfly wings. Also can be PU one side and Genius weft on the other side and hole is in PU side.

2. Boasts 100% cuticle-aligned Remy hair, no shedding, and trimming freely, with a reinforced middle connection supporting longer length.

Installation Method

1. Relies on the traditional sew-in technique, which needs thread and multiple passes through the track row.

2. While the process is time-intensive, most stylists are familiar with it. The end result is a flat, flexible install that suits clients with fine or average-density blonde hair.

No sewing—stylists secure the weft using beads or rings, clipping and fastening directly through the central butterfly hole. This method is quicker, cleaner, and easier to control, reducing tension on natural hair. It’s also better for maintenance/move-ups and more approachable for stylists-beginner.
Stylist Benefits Familiar with the traditional sew-in process; delivers a consistently flat, flexible finish. Significantly faster installation times, neater placement, reduced tension on clients' hair, simpler maintenance, and easier to learn compared to sewing.
Client Comfort High comfort level due to its thin, lightweight base, especially for those with fine hair Minimized scalp pressure for long-term wear; no bulk thread, making it perfect for finer blonde hair where sewing tension could be an issue.

Step by Step Installing

Bead-In

1. Make a parting and use the clips to fix the hair. Use the hair gripper to hold flowaway hair for a clean result.

2. Make the starting point where you want to place the weft with a small clip. This is the place where you also start to build the row with rings.

3. Take a small strand of hair and apply a Soft Ring Repeat until you have a complete row.

Sew-In

1. Use a rounded needle for the thread. The first stitch is made from the top of the weft through the first strand with a soft ring.

2. Push the needle through the loop at the end of your last stitch. Pull the thread tight to secure the extension. Continue for the whole weft

3. When you finish, secure the thread with a double knot and cut off the rest of the thread.

4. Remove all clipsand and give a check if the weft sits tight around the scalp.

5. And your are done with the seamless integration of the Genius Backstage Weft.

FAQ

1. What hair quality do you offer?

We mainly offer two grades:

• Cuticle Remy – cuticles kept intact and aligned, so it’s less likely to tangle and can last longer. It’s for the top-end market.

• Standard Remy – Also good quality, but with more processing. It’s more cost-effective and works well for mid-market and large orders.


2. What’s the difference between Cuticle Remy and Standard Remy?

Cuticle Remy has the cuticle layer mostly intact and aligned in the same direction. This makes it is not-inclined to tangle and generally longer-lasting.

Standard Remy is still Remy hair, but it goes through more processing, so the cuticle is stripped partly during production. It balance well for quality and price and your best option if you’re targeting the mid-market.

Yes, Lum Hair can do both double drawn and single drawn for most of hair extensions.Double drawn is thicker from root to tip and looks fuller, while single drawn is cheaper and more natural-looking.
