Genius PU clip ins represent the latest innovation in hair extension technology, combining the best of both worlds for ultimate invisibility. Unlike traditional PU seamless clip ins, Genius PU extensions feature a revolutionary dual-sided design: a thin polyurethane (PU) strip on the clip side and a genius weft construction on the hair side. This advanced engineering significantly reduces PU strip visibility while creating an even more natural, undetectable blend with your hair.
The genius weft backing allows the hair to lay flatter and more naturally against your scalp, while the ultra-thin PU strip on the clip side ensures secure attachment without bulk. This innovative combination delivers superior comfort and the most seamless, invisible result available.

Why Choose Genius PU Over Traditional PU Seamless Clip Ins?
The genius weft backing provides superior concealment by reducing the visible PU strip area, creating a more natural hairline and parting. The dual-sided construction means less PU material is exposed, making these extensions even more invisible than traditional PU seamless clip ins. The result is the most undetectable, comfortable, and natural-looking clip-in extension available today.
Coverage Guide:
- 1-2 packs recommended for a full head
- 135G-150G provides excellent volume and length
- Multiple weft sizes allow for customized placement and natural layering



- Please select the corresponding clips and lower the opening direction of the clips
- Make a U part on your back head that spans from ear to ear. Snap open each clip on of your wefts
- Place the clips along the line and snap shut. Make sure it's secure
- Add another weft following step 3. continue to add wefts until the desired style is achieved
- Or you can add in wefts from the top (around the top of the ear) and work your way down
- Once the back is finished, you may use the single clip pieces to fill the sides
