Background: Alopecia areata is considered to be an autoimmune disease. It consists of patchy hair loss of the scalp and the eyebrows, making it a disfiguring condition. This 10 year study was designed to assess the usefulness of the treatment of the eyebrows with dermatography as a relatively quick and simple method to obtain a cosmetically satisfactory result. Materials and methods: The eyebrow areas were covered with a halftone pattern of tiny dots of color pigments, using a Van der Velden Derma- injector, without anesthesia. On average, two to three dermatography sessions of 1 h were required. The follow-up was 4 years. Results: Thirty three patients, most of whom had been previously treated with a sensitizer such as dinitrochlorobenzene (DNCB), were treated with dermatography. Four patients had also been treated by a beautician with a crude form of tattooing. The results in 30 patients were excellent. In three patients the results were good. Conclusions: Dermatography is a technique offering a good alternative for timeconsuming, troublesome treatment modalities that often have considerable side-effects. With dermatography, no side-effects were found.
