Extension hair piece and hair extension using the device

Abstract

Disclosed is a hair extension device. The device comprises a tube, a hair bundle and a link. The tube is configured to deform more easily in a first direction than in a second direction when the same amount of crimping force is applied to the tube. The first and second directions are on a cross-sectional plane, in which the tube's cross-section forms a closed loop. Further the tube may have a desirable crimping direction and be shaped to substantially induce grabbing of the tube with a crimping tool toward a desirable orientation thereof for crimping in the desirable crimping direction. The hair bundle comprises a plurality of extension hair strands bound together. The link links the hair bundle to the tube.
