Our new Polyester Nylon Thread was carefully selected to create cleaner, more natural-looking extension installs while improving long-term performance behind the chair.

Unlike traditional cotton-blend threads, this premium thread is designed to resist water absorption, helping reduce swelling that can contribute to loose wefts or tension changes after washing.

Why Stylists Love It

✔ More natural-looking finish that blends seamlessly into the weft

✔ Water-resistant fibers won’t absorb moisture like traditional thread

✔ Helps maintain consistent tension after shampooing

✔ Smooth glide makes stitching easier and faster

✔ Strong, durable construction for long-lasting wear

✔ Soft, flexible feel for comfortable installs

✔ Colorfast to help maintain a professional appearance over time

 Small: 1000m
