A structure for implantation below the surface of the epidermis of the scalp includes a group of human hair shafts embedded within a non-hydrophilic core. The core is surrounded by a cylindrical annulus of hydrophilic material which possesses a property of volumetric expansion of at least two fold after fixation within the human scalp. Through such expansion an artificial arch or within the scalp is obtained.
