What Is Sew-in Weft Extensions?

Sew-in extensions, or weft extensions, are a type of permanent hair extension. A professional stylist applies them by sewing the weft onto pre-braided hair or micro-beads. The sew-in options include Hand-tied, Genius, Flat, and Machine Wefts. They don’t need glue or heat, making them a safe choice for adding length and volume. Sew-ins blend well with natural hair, giving a full, layered look. They also protect your hair from heat damage, keeping it healthy.

Flexible installs with sew-in or bead methods.

Quick removal in minutes, no adhesive needed.

No glue or heat, safe for all hair types.
