Weaving is the most common means of installing human hair extensions, wherein concealed micro braids hold the human hair extensions in place. However, since the entire weight of the human hair extensions is held up by these braids, their use results in stress on the natural hair, especially near the area of attachment. Sometimes, the weight of the human hair extensions can loosen them, resulting in breaking away of the extensions and strands of the natural hair as well. Another method is metal tubing, where the human hair extensions are attached to a metal tube which is fastened over natural hair. This process is not recommended for fine hair since the tube itself is heavy and also because the removal process is cumbersome. Heat-shrink tubing is relatively easier to remove and is also lighter in weight, but does not last long since the tubes slacken after a few washes. Bonding is a low cost and fast application method for human hair extensions, provided the glue used is of good quality. For removal, the human hair extensions have to be saturated with oil and heated – this is time-consuming and messy. An alternative to this is the use of special adhesives instead of glue. Most modern adhesives are capable of withstanding chemical and heat treatments, and can be easily removed using special adhesive removers, which covert the adhesive into a dry powder.
