Our 18-inch Kinky Curly Hair Weft features tight, springy 3C–4B curls with a natural density and mid-length finish that falls just below the shoulders. Made from 100% virgin human hair, this texture blends seamlessly with coily or textured hair, making it a go-to for women who want natural-looking volume with added length.
The curls are full of bounce, moisture-friendly, and easy to maintain with the right hydration and curl care routine. Whether you're wearing a defined twist-out, wash-and-go style, or silk press, this kinky curly texture mimics your own curls for a seamless finish. Each bundle is tightly stitched for durability and minimal shedding.
Each bundle weighs approximately 100g (3.5 oz). For a complete installation, we recommend 3 bundles. With proper care, this virgin kinky curly hair can last up to 24 months. It can also be straightened or colored by a professional without compromising the integrity of the curls.

Just Know
Curly hair extensions transform your look instantly, but they do require care to keep their texture lush and frizz-resistant. This guide gives you a simple daily + nightly routine, smart heat-styling tips, and the go-to products we trust.
Daily Care Routine
1. Detangling
- Always detangle while wet: Use a spray leave-in conditioner to make detangling easier. Start from the bottom and work your way up to prevent breakage.
- Wide-tooth comb or special brush: Gently detangle daily to prevent matting. Use a mist spray bottle with fresh water to help manage curls daily.
2. Washing and Conditioning
- Sulfate-free products: Use a sulfate-free, moisturizing shampoo and conditioner to retain natural oils and keep the hair hydrated. We recommend washing no more than once a week.
Recommendation: Sulfate-free shampoo
- Leave-in conditioner: Apply to the ends to keep them moisturized and prevent dryness.
- Curl define: Use a curl-defining cream or mousse to enhance and define your natural curls.
Recommendation: Curl Define Cream
- Heat protectant: Always apply a heat protectant before using heat styling tools to maintain the curl pattern.
Recommendation: Heat Protectant
- Avoid excessive heat: Use styling tools on medium heat settings. Including blow-dryer and flat irons.
3. Trimming
- Regular trims: Trim every 6-8 weeks to eliminate split ends and maintain healthy curls.
Night Care Routine
1. Pre-Sleep Preparation
- Braid or twist: Loosely braid or twist your hair to prevent tangling and matting.
- Moisturize: Apply a small amount of leave-in conditioner or a lightweight serum to the ends.
2. Sleep Protection
- Satin bonnet or silk pillowcase: Use an SL Raw No-slip satin bonnet or silk pillowcase to reduce friction and prevent dryness.
