PU Hole Flat Weft Hair Extensions, or Butterfly Weft Extensions, enhance the ultra-thin design of Genius Wefts. They have a double-sided design: one side features smooth, machine-inserted wefts that mimic natural hair growth for an undetectable appearance, while the other side has a perforated PU design that is ultra-thin and lightweight, ensuring comfort and seamless blending with natural hair. This blend of comfort and durability makes them a popular choice for achieving perfect volume.

Hand-tied wefts cannot be easily cut due to their hand-knotting method. In contrast, butterfly wefts do not unravel when cut, making them easier to customize and install. They also do not damage your natural hair and wefts during removal, allowing for repeated use.
Compared to tape-in extensions, tape-in wefts have limited width and cannot fit all areas of the head. The process of removing and reapplying tape-ins requires adhesive remover to eliminate the glue and clean any residue from the hair, making it more time-consuming. In contrast, PU hole weft hair can be installed quickly and easily with beads, allowing for fast application and removal.

Opt for Sulfate-Free Shampoo:
Avoid shampoos containing sulfates as they can harm hair extensions. While sulfates create lather, they strip natural oils from the hair, resulting in dryness and frizz.
