ZHENLISI Deep Wave Curly Hair Bundles 20in Natural Black (4-Pack) Heat-Resistant, Low-Shed

ZHENLISI Deep Wave Bundles are a pack of four heat-resistant synthetic curly wefts that deliver full, defined waves in a natural black 20-inch quick-weave style.

These ZHENLISI deep wave synthetic hair bundles are designed to recreate the look and soft hand of human curly hair while remaining an affordable, low-maintenance alternative. Each pack contains four 20-inch bundles in Color 2# (natural black), with tight, uniform waves and reinforced double-machine wefts to reduce shedding. Lightweight and ready to install, the wefts offer styling flexibility for ponytails, sew-ins, and quick weave applications. The fibers are heat-tolerant up to 180°C (356°F), allowing for light flat-ironing to smooth strands, though they do not hold a curl with electric curling tools.

How much hair do I get and will it look full?

Each pack includes four bundles, with each bundle weighing approximately 70 grams (2.5 oz). One pack can create a neat ponytail or a lighter sew-in style; for a visibly fuller, voluminous hairstyle, two packs are recommended.

• 4 bundles per pack, 20 inches length, Color 2# (natural black)
• Single bundle weight ~70 g (2.5 oz) for measured layering
• Use one pack for a ponytail, two packs for full sew-ins
• Layer and blend easily with natural hair for added volume

Will these synthetic bundles tangle or shed?

ZHENLISI uses a double-layer reinforced weft with professional machine sewing to minimize shedding and tangling. The deep wave pattern stays defined with proper care, and the wefts are designed to sit flat against the scalp for smoother installs that reduce friction-related matting.

• Double machine weft construction reduces shedding
• Tight, consistent wave pattern resists frizz with maintenance
• Ideal for sew-ins and quick-weave techniques to avoid bulk
• Recommended detangling from ends to roots with a wide-tooth comb

Can I style these bundles with heat tools?

The synthetic fibers are heat resistant and can be flat-ironed at temperatures up to 180°C (356°F) to smooth sections. However, these bundles are not compatible with electric curling tools for creating new curls; excessive heat may damage the fiber texture and reduce longevity.

• Safe to flat-iron at or below 180°C (356°F)
• Do not use electric curlers to re-curl the deep wave pattern
• Use low heat and test a small strand first
• Apply heat protectant sprays designed for synthetic fibers when possible

How easy is installation and everyday care?

These quick-weave synthetic bundles are made for fast installs and straightforward upkeep. They can be sewn, glued, or used in ponytail creations; routine gentle washing and air-drying help preserve the wave definition and sheen.

• Suitable for sew-ins, glue-in quick weaves, or ponytail extensions
• Hand wash with mild shampoo and cold water; air dry flat
• Comb gently with wide-tooth comb to maintain wave shape
• Store on a hanger or in a breathable bag to avoid flattening

Who is this for: ZHENLISI Deep Wave Bundles are ideal for anyone seeking affordable, ready-to-wear curly extensions in natural black without the commitment or cost of human hair. They suit beginners and stylists who want consistent wave pattern, low shedding wefts, and the ability to smooth sections with a flat iron. Choose one pack for lighter styles or quick ponytails and two packs when you want a fuller, salon-style sew-in effect.
