Background: Low-level laser therapy (LLLT) has been reported to promote hair growth in androgenic alopecia (AGA). Objectives: The aim of this study is to investigate clinical efficacy and safety of a brand-new home-use LLLT device with a newly designed array of light source and software optimized for individual types of AGA. Methods: The study was designed and conducted as a randomized, double-blind, sham device-controlled trial. 48 subjects (39 men and 9 women) were participated and randomly assigned in a 2:1 ratio to use either test device (LG Pra’L HGN1, LG electronics, Korea) or sham device. The subjects used LLLT device 3 times a week for a total of 16 weeks. Phototrichogram was used to measure hair density and hair thickness at 0, 8, and 16-week. Adverse events were closely monitored. Results: After 16 weeks using the device, the test group showed significant increase in hair terms of hair density and hair thickness compared to control. In the test group, the hair density increased 9.94% at 8-week and 18.34% at 16-week from baseline. The hair thickness increased 10.08% at 8-week and 16.29% at 16-week from baseline, too. Conclusion: The home-use LLLT device with novel array of light source and individualized program according to the types of hair loss appears to be an effective and safe treatment modality for both male and female AGA patients.
