A hair weft is an extension of the hair designed to make one’s hair appear thicker or longer. This type of hair piece is particularly popular among teenagers and young adults, though they are accessible for most ages. Both synthetic hair pieces as well as human hair pieces are used to make hair wefts.
Another term often used in place of hair weft is hair curtain. This is due to the curtain-like appearance of the weft itself. Unlike many other types of hair extensions, hair wefts are usually long sections of hair that are glued to the scalp or attached in another manner. Though many hair wefts are straight, they are also available in wavy and curly textures.
Wefts are typically available in most lengths desired. If made from human hair, a hair weft may be cut, straightened, dyed, curled, or treated otherwise as real hair. Some synthetic wefts may be treated similarly, though others may break down or yield results other than the ones intended, such as discoloration.
Many people apply hair extensions for long-term use. Though a hair weft can be used repeatedly for long-term use, it can also be attached as a temporary application. Some people use hair wefts as such for party costumes, theater performances, and other short-term needs. Most hair wefts cover a limited area of the scalp, hence many people opt to purchase four to six wefts to create a uniform appearance.
Most customers who use a hair weft for long-term needs prefer very realistic or human extensions. High-quality hair wefts made from real human hair are known as remy hair. Remy hair retains its cuticle layer from its original host, making it appear more natural than synthetic or damaged hair. Bases for hair wefts are sealed with a coating, such as polyurethane.
There are several different methods used to attach a hair weft to a person’s hair. One of the most common methods is applying a special glue to the hair. This method can cause a health concern, however, as many hair glues contain formaldehyde and other potentially hazardous chemicals.
Double-sided tape adhesive designed just for hair wefts is also available. This adhesive material can typically last for up to two weeks. Handmade hair wefts may require a skin weft application. This is done through a skin weft sealer tool, which has a similar appearance to a hair straightener. Hair weft removal products are also available.
