Definitions

• Hair extensions are used to add length or fullness to a person's natural head of hair for cosmetic reasons.
• These devices include supplemental hairs from another human head or from synthetic sources to augment natural hairs on a person's head.
• the supplemental hairs are integrated into a person' s natural head of hair using one of a number of methods. However, many of these methods can be time consuming, costly, and/or damaging to a person's natural head of hair. Furthermore, many of these methods leave the wearer with an unnatural look to their hairstyle.
