What is the primary purpose of sealing the weft on hair extensions?

Sealing the weft on hair extensions primarily serves the purpose of preventing shedding and extending the life of the extensions. When extensions are manufactured, the weft—the area where the hair is sewn together—can become loose over time, leading to shedding and loss of hair fibers. By sealing the weft, stylists create a barrier that helps keep the hair strands securely in place, minimizing the risk of shedding. This preservation not only prolongs the overall appearance and usability of the extensions but also enhances the experience for the wearer, as they can enjoy their extensions without the constant worry of hair loss.

Other options, while they may sound appealing in a cosmetic sense, do not address the functional benefits of sealing the weft. Enhancing color or making the extensions shine relates more to cosmetic treatments or product application rather than to the structural integrity and longevity of the weft. Similarly, changing the texture of the hair doesn't relate to the sealing process; it involves different treatments or types of hair rather than the sealing technique itself.
