An artificial hair having a physiologically active surface which is formed by a such manner that protein (collagen) molecules are bonded chemically to the graft-polymerized chains introduced onto the surface of the artificial hair. When the artificial hair is implanted into a human body skin, the collagen layer 11 fixed to the surface of the artificial hair having a root part 12 is integrally assimilated and bonded to collagens in the epidermis 4, the corium layer 5, the subcutaneous tissue 6 and the galea 7, whereby the artificial hair can be firmly fixed. Thus, this artificial hair exhibits a low infection rate, a high success rate and is not accompanied by down-growth.

Cheveu synthétique comportant à sa surface une couche biocompatible formée par la liaison chimique de collagène sur une chaîne de polymère greffé introduite dans la surface. Lorsque ce cheveu est implanté directement dans la peau humaine, une couche de collagène (11) servant de couche biocompatible fixée à la surface du cheveu synthétique (10) muni d'une racine (12), est intégrée de façon assimilable avec les collagènes présents dans l'épiderme (4), le derme (5), le tissu sous-cutané (6) et l'aponévrose épicrânienne (7), ce qui fixe solidement le cheveu synthétique. Comme cet implant de cheveu ne provoque pas d'incurvation du cuir chevelu, même après un certain temps, il s'avère très résistant à l'invasion de bactéries pathogènes et le taux de fixation après implantation est amélioré.
