12A Natural Black Body Wave Human Hair Bundles Flat Weft 100g

12A Natural Black Body Wave Flat Weft Human Hair Bundles

Create a fuller, longer hairstyle with 12A Body Wave Human Hair Bundles in Natural Black #1B. Made from 100% virgin human hair, these bundles feature soft, flowing body waves with natural movement and a rich black finish that works well for classic sew-in and other compatible weft-based extension styles. Each bundle contains 100g of hair and is available in lengths from 12 to 30 inches, giving you flexibility to build anything from subtle added volume to a long, full body wave look.

The defining feature is the flat weft construction. Instead of a thick, bulky seam, the weft is designed with a thinner, flatter profile that can lie more closely against the installation base. This creates a cleaner, lower-profile finish while helping the installed hair feel less bulky. The bundles also feature full-looking ends and a consistent body wave pattern through the lengths. With 1-, 3-, and 4-bundle options, you can select the amount of hair according to your desired length, coverage, and volume.

Recommended Bundle Guide

• 1 Bundle: Suitable for adding extra volume, filling selected areas, or supplementing an existing hairstyle.

• 4 Bundles: Better suited to thicker, fuller styles or longer installations where additional coverage is needed.
• Lengths Over 22": Four bundles are generally recommended when creating a fuller long-hair look because longer bundles provide less visual coverage per bundle.

How to Use

1. Choose the desired bundle length and quantity according to your planned hairstyle and fullness.
2. Have the flat weft installed using an appropriate weft-based extension method, preferably by an experienced stylist.
3. Blend and style the installed hair with your natural hair or compatible closure/frontal if used.
4. Gently maintain the body wave pattern with conditioning, low-manipulation styling, and careful detangling.

Styling & Care

Detangle the hair gently from the ends upward before washing or styling. Use products suitable for human hair extensions, condition regularly, and avoid aggressive brushing that may disturb the body wave pattern. After washing, gently reshape the waves with your fingers and allow the hair to air dry whenever possible.

Because the bundles are made from human hair, they can be dyed, bleached, or heat styled. Always perform a strand test before chemical processing, especially when bleaching or making a significant color change. Use heat protection before applying curling irons, flat irons, or other heated tools.

Perfect For

These Natural Black #1B flat weft body wave bundles are suitable for sew-in hairstyles, added length, fuller everyday looks, special occasions, custom-colored styles, and customers who prefer a low-profile weft construction. The wide 12-30 inch length range also makes it possible to create shorter layered looks, medium-length styles, or dramatic long body wave hair.

Frequently Asked Questions

How many bundles do I need for a full head? Three to four bundles are typically recommended. Three bundles work well for many standard full-head styles, while four bundles are recommended for extra fullness or lengths over 22 inches.

Can I dye or bleach the bundles? Yes. The hair is 100% virgin human hair and can be dyed or bleached. Perform a strand test first before processing the full bundle.

What is a flat weft? A flat weft uses a thinner, flatter seam designed to lie closer to the installation base than a traditional bulky weft, helping create a lower-profile finish.

Will the body wave texture remain after washing? The wave pattern can be maintained with appropriate care. Use a curl-friendly conditioner, reshape the waves while damp, and allow the hair to air dry.

How much does each bundle weigh? Each bundle contains approximately 100g of human hair according to the supplied product specification.
