[Complications of synthetic hair implantation].

Five men (average age 35 years) suffering from the sequelae of hair implants were examined in the course of claims for legal compensation. Polyether amide hair fibres had been implanted, 1000 per patient and session. In all cases the improved implantation technique with a fine needle and subcutaneous knotting had been used in a total of three institutions. Three patients developed bacterial folliculitis after 4-8 weeks; in the other two patients this developed later, after 3-6 months. In two patients the possible triggering event was the wearing of a motorcycle helmet and a vacation in a tropical climate respectively. In another patient the artificial hair curled considerably after he visited a sauna. The implanted hair had fallen out almost completely in all cases (100% in two patients after 9-12 months, 50-75% in three patients after 7 months to 2 years). All patients showed cosmetically disturbing small scars and pigmentary changes. Despite an apparently improved complication rate, the new technique of hair fibre implantation remains a doubtful procedure and cannot be recommended in view of possible permanent sequelae.
