What Is Hair Weft Thread Used For?

Hair weft thread is used to sew hair extension wefts onto braided cornrows during a traditional sew-in weave installation. It is the preferred method for securing wefts because it creates a flat, natural-looking base that can last 6–8 weeks with proper care.

How to Choose the Right Thread Color

Match your thread color to your natural hair or the weft color for the most discreet install. Use Black for jet black or off-black hair, Dark Brown for deep brunette shades, Medium Brown for chestnut or warm brown tones, and Blonde for light, golden, or highlighted extensions.
