Abstract: Disclosed herein are assemblies and methods for extending and/or thickening hair. A weft of hair or hair-like strands are coupled together at a first end at an elongate connection strip. The connection strip is made from a solid material and has an elongate shape. A length of the elongate shape of the connection strip is substantially greater than a width and a thickness of the connection strip. The length of the connection strip defines a width of the weft of hair. A set of magnets is coupled to the connection strip. A second connection strip is coupled to a second set of magnets. The second connection strip corresponds to the first connection strip and the second set of magnets are positioned to magnetically couple to the first set of magnets to engage, grip, pinch, squeeze, hold, or otherwise secure a portion of naturally growing hair of a user to secure the assembly to the hair of the user.
