ZHENLISI Body Wave Synthetic Hair Bundles 16/18/18/20-inch Pack — Black 1B, Pre-sewn Heat-Resistant Tracks

ZHENLISI Body Wave synthetic hair bundles are pre-sewn, heat-resistant quick-weave extensions in a 16/18/18/20-inch pack that deliver a soft, body-wave look without the cost of human hair.

These ZHENLISI bundles are designed to give an easy, full-coverage weave using four machine-sewn tracks in natural black (1B#). Each pack includes one bundle per specified length (16, 18, 18, 20 inches) and weighs approximately 70 grams (2.5 oz) per bundle, providing a ready-made textured style for fast installation and long-lasting wear.

How do these bundles create a full head of hair quickly?

The four-track configuration allows stylists or DIYers to lay wide wefts that cover more scalp per pass, cutting installation time. One pack is suitable for a natural full look; for maximum thickness, two packs are recommended.

• Pack contains four bundles with graduated lengths for layered styling.
• Each bundle weighs about 70 g (2.5 oz) for predictable coverage.
• Double machine weft reduces shedding during installation.
• Pre-measured tracks simplify quick-weave and sew-in techniques.

Can I style these synthetic bundles with heat tools?

ZHENLISI’s fibers are heat-resistant and can be flat-ironed at temperatures up to 180°C (356°F). The fiber will not reliably hold a curl from a standard electric curler, so use straightening or low-heat smoothing methods for best results.

• Safe to flat-iron at or below 180°C to smooth fibers.
• Avoid high-temperature curling tools to prevent damage.
• Work in small sections and use heat protectant for longevity.
• Cold-styling (rollers, braids) can create temporary waves.

What makes the weave durable and low-maintenance?

These bundles feature a reinforced double-layer weft and neat machine sewing to minimize shedding and tangling. The synthetic fiber retains a soft, human-like texture without the daily upkeep required by human hair.

• Double-layer reinforced weft for reduced shedding.
• Tight, professional machine stitching for secure tracks.
• Body wave texture resists frizz and holds shape between washes.
• Easy-care washing and detangling with gentle products.

Which installation methods suit ZHENLISI quick weave tracks?

These bundles work well for quick-weave (glue or bond over braids), traditional sew-ins, and certain wig constructions where pre-sewn tracks streamline the build. Their length mix creates natural layers without additional cutting.

• Quick-weave glue/bond application for fast salon-ready results.
• Sew-in and braiding techniques for longer-wear styles.
• Wig-making or extensions for easy multi-length layering.
• Blend with natural hair at the partline for seamless transition.

Who is this for: ZHENLISI Body Wave synthetic bundles are ideal for women seeking an affordable, low-maintenance alternative to human-hair weaves—perfect for budget-conscious shoppers, stylists offering quick-change looks, or anyone wanting immediate body-wave volume without lengthy styling.
