What Are Weft Hair Extensions? (And Are They Right for You?)Updated 6 hours ago
Weft hair extensions are a popular and trusted method for adding length, fullness, and volume—without sacrificing the integrity of your natural hair. At SL Raw Virgin Hair, our wefts are made from 100% raw, ethically sourced human hair, sewn into a continuous strip (also known as a “track”) that can be applied using several different methods.
Types of Weft Hair Extensions
There are three primary types of weft hair:
1. Machine-Wefted Hair
This is the most common type. The hair is stitched together by machine, creating a strong, durable track. Ideal for sew-in installs and custom wigs.
2. Hand-Tied Wefts
These are thinner and more flexible, designed to lay flat against the scalp. They’re best suited for clients with fine hair and require a specialist for application.
3. Flat-Weft or Seamless Wefts
These modern wefts have a thinner base and are virtually undetectable, offering a more natural, lightweight feel.

How Are Wefts Installed?
Weft extensions are typically applied using the braid-down method (also known as a sew-in), where your natural hair is cornrowed and the weft is sewn along the braid using a curved needle and thread.
Other options include:
Microlink weft installs
Glue-in wefts (not recommended for raw hair)
Custom wig units made from wefts

You may be a great candidate for weft hair extensions if:
You want fuller hair without excessive heat or chemical processing
You prefer a long-lasting install (wefts can last 6–8 weeks per install)
You want a protective style that supports natural hair growth underneath
You’re comfortable seeing a stylist for installation and takedown
