Butterfly Weft, also known as Genius Hole Weft, PU Hole Weft, or Invisible Hole Weft in some markets, is a modern professional hair extension that combines a thin, flexible weft with a convenient attachment system. Unlike traditional machine wefts, many Butterfly Weft designs feature a flat base with pre-punched holes that allow stylists to secure the weft with micro rings or beads. Some constructions use a PU base, while others use hybrid or silk-like materials, so always confirm specifications with the manufacturer.

The main advantage is low-profile installation with targeted volume. Butterfly/Genius Hole Wefts are commonly used for adding length and density while keeping the attachment relatively flat and discreet. They are particularly useful for fine-to-medium hair, crown areas, side sections, and clients who want a seamless result without glue or tape. Depending on the construction, some products are available in approximately 50–100g formats, with different lengths, colors, widths, and hair grades available for salon and wholesale applications.

Main Applications

Butterfly Weft / Genius Hole Wefts can be used for:

• Fine and medium-density hair — adding volume without a bulky traditional weft.
• Crown and side areas — where a flat, discreet attachment is important.
• Full-head volume — multiple rows can be installed according to the client’s hair density and desired result.
• Length enhancement — available in longer lengths for clients who want both length and fullness.
• Salon professional services — suitable for semi-permanent extension applications.
• Wholesale and private-label brands — manufacturers can customize hair length, weight, color, texture, packaging, and other specifications.

The attachment method is one of the main differences between products sold under this category. Some Butterfly Hole Wefts are designed specifically for microbead installation through the pre-punched holes, while Genius Wefts are commonly used with beaded or sewn installation.

Butterfly Weft vs Genius Weft vs Other Wefts

Compared with traditional machine wefts, Butterfly Wefts focus more heavily on a thin, low-profile attachment. Compared with standard Genius Wefts, the key differentiator is often the pre-punched hole design and installation system, although naming and construction vary between manufacturers.

Why Choose Butterfly Weft / Genius Hole Wefts?

For salons and professional extension brands, the category offers a useful combination of low profile, flexible styling, targeted placement, and relatively fast bead-based installation. Some current commercial products come in 50g and 100g configurations, while individual manufacturers may offer customized weights and lengths.

For B2B buyers, the most important specifications to compare go beyond the product name. Check the base material, thickness, hole structure, weft width, grams per piece, hair length, hair quality, color range, cuttability, attachment method, and expected maintenance schedule. Because “Butterfly Weft” and “Genius Hole Weft” are used differently by different suppliers, we recommend a physical sample before a bulk order.
