Hair extensions are the fastest-growing hairdressing service in the marketplace, according to Theresa Bullock in her book "eXtensions: The Official Guide to Hair Extensions." The service has become as popular and commonplace as coloring and perms. Women from all ethnic and economic backgrounds wear extensions.

Hair extensions and hair weaves are not the same. Extensions are the pieces of hair added during the weaving process. Weaves are the result of adding hair extensions. A person who gets a weave has hair extensions added to her hair.

A quick weave is a technique requiring the use of bonding glue. With a regular weave, extensions are sewn into braided hair. This process normally takes anywhere from 3 to 5 hours. A quick weave takes less time. The hair is wrapped tightly around the head using hair gel. Sometimes, the hair is also placed into a stocking cap. The extensions are then attached with bonding glue.

Human hair is sometimes used in quick weaves. It is more expensive than synthetic hair and requires the same care as the wearer’s natural hair. According to the HairExtensionGuide.com, the quality of human hair depends on its origins. Healthy hair is desirable because unhealthy hair makes extensions that are dry, brittle and difficult to manage.

Synthetic hair is a man-made fiber that looks similar to natural hair. Quick weaves often use synthetic hair because it is inexpensive and easy to obtain. The two most widely used forms of synthetic hair are Kanekalon and Toyokalon.

People of Indian or Asian descent usually provide the hair for human hair extensions. This is the highest quality of hair available.
