Background: Super Lizer™ (SL), which emits linear polarized infrared, has been recently used for the treatment of arthralgia, neuralgia and skin ulcer. Very recently SL therapy for alopecia areata (AA) has also been reported mostly from Japanese institutions. Action of infrared on AA has not been cleared. But increased blood flow and HGF expression have been considered as mainfunctions.

In this study, we attempted to treat the multiple cases of chronic stable AA who have only short fine hairs by SL irradiation.

Methods: Irradiation with infrared radiation using SL was performed on twenty-five AA patients (4 single AA, 9 MAA, 7 AT and 5 AU) whose hair condition had been unchanged for more than last three months. The patients were irradiated by scanning method once every two or three weeks up to 4 years.

Results: Nineteen out of 25 (76.0%) patients showed thick terminal hair regrowth. Five patients did not show any change on hair growth. One patient revealed recurrence during later period of treatment. Thirteen out of 15 (86.6%) patients whose AA area where initially occupied by fine hairs more than 80% of area, eventually achieved terminal total hair regrowth. All of single AA and MAA patients revealed improved hair growth.

Conclusions: These results suggest that SL is a useful alternative treatment for the chronic stable AA patients, particularly in inducing for thick terminal hair transformation.
