Hair extensions can be broadly classified into two main categories: wefts and individual extensions. Wefts consist of hair that is sewn or bonded onto a continuous strip, allowing stylists to install multiple strands at once. These are ideal for adding significant length and volume efficiently. In contrast, individual extensions are applied in small sections, offering a more customized and natural integration with the client’s hair. Individual extensions provide greater movement and flexibility, making them a popular choice for clients looking for a seamless, long-term extension solution.
Beyond these categories, hair extensions are installed using three primary application techniques: adhesive, sewn, and bead-based methods. Adhesive applications, such as tape-in or keratin bond extensions, rely on specialized glues or keratin attachments to bond extensions to the natural hair. These methods provide a long-lasting hold with a natural look but require precise application and removal. Sewn-in extensions, commonly used with wefts, involve braiding the natural hair into cornrows and sewing the weft onto the braids. This technique offers a secure and durable fit, making it an excellent option for clients with thick or textured hair. Bead-based applications, such as micro-link or I-tip extensions, use small metal rings to attach hair strands or wefts to the client’s natural hair without the need for heat or glue. This method is valued for its flexibility, easy maintenance, and minimal damage to natural hair.
Choosing the right extension type and application method depends on factors such as hair type, lifestyle, and maintenance preferences. Clients looking for a quick, semi-permanent solution may opt for tape-ins, while those seeking a more durable and long-term extension may prefer sew-ins or bead-based methods. Throughout this section, we will explore each category and application technique in greater depth, equipping stylists with the knowledge to select the best options for their clients' unique needs.

WEFTS
Wefts are one of the two primary categories of hair extensions, consisting of multiple strands of hair sewn, bonded, or molded onto a continuous strip. They are designed to cover larger sections of the head efficiently, making them a popular choice for clients seeking significant volume and length. A defining characteristic of wefts is their anchor points, or touchpoints to the head, which determine how securely and evenly they attach to the natural hair. The method of installation—whether sewn, taped, or attached with beads—affects how these anchor points interact with the client’s scalp and hair, influencing comfort, durability, and styling versatility. Wefts provide even weight distribution across the application area, reducing strain on individual hair strands and minimizing potential damage when installed correctly.
There are several types of wefts, each offering unique benefits depending on hair type and lifestyle. Machine-sewn weftsare durable and designed for thick hair that can support a sturdier extension. Hand-tied wefts are thinner and more lightweight, ideal for fine or fragile hair since they create a more natural blend with less bulk. Injection-molded wefts, a newer innovation, are designed to mimic natural hair growth by embedding hair strands directly into a flexible, skin-like base. The application technique influences how the anchor points interact with the hair—sewn-in wefts rely on a braided foundation for support, while tape-in wefts use adhesive to bond to the natural hair, and bead-applied wefts secure the extensions with micro-links. Choosing the right weft type and application method ensures both longevity and a seamless, comfortable fit for the client.
