Linear polarized infrared irradiation using Super Lizer is an effective treatment for multiple-type alopecia areata

Background 

Super Lizer is a linear polarized light instrument, which has been used with good effect in orthopedics and anesthesiology to treat arthralgia and neuralgia with a high output of infrared radiation.

Aim 

To test Super Lizer's efficacy for the treatment of alopecia areata.

Methods 

Fifteen patients over 18 years of age, diagnosed with alopecia areata and displaying symptoms of patchy hair loss, were topically irradiated with infrared radiation using the Super Lizer. The patients were irradiated intermittently for an interval of 3 min once every week or every 2 weeks.

Results 

Seven of 15 (46.7%) of the irradiated areas showed hair regrowth 1.6 months earlier than the nonirradiated areas (2 official approval, P = 0.003).

With regard to adverse effects caused by Super Lizer treatment, only one patient complained of a sensation of heat in the irradiated area.

Conclusions 

These findings suggest that Super Lizer, with its noninvasive properties, is a useful apparatus for the treatment of mild forms of alopecia areata.
