Systems and methods for hair extensions

Abstract

A hair extension system includes a base and a removable hair extension. The base has a substrate with opposing end coupling mechanisms and an elongated coupling mechanism extending along its central length. The extension includes corresponding end coupling mechanisms, such as hooks engageable with base loops, and a second elongated coupling mechanism. The elongated mechanisms are complementary press-lock fasteners comprising arrays of protrusions and voids arranged at a regular pitch to interleave in a press-fit. End caps on the base and extension provide channels that stabilize the end couplings against rotation and lateral movement and present flush exterior or user-facing surfaces. The base is attachable to the wearer through adhesive, tape, clips, beads, dissolving or non-dissolving threads, or stitches through a mesh, and may be fixed directly to the scalp or indirectly to a hair base formed from natural hair.
