Abstract

In this study, we tried to investigate the efficacy of combined light therapy using low-power lasers at 655 nm and LEDs emitting wavelengths at 625 ± 5 nm and 850 ± 10 nm in hair loss and scalp. A total of 33 subjects were enrolled in this clinical trial. Each subject used the LLLT and LED device on the scalp for 10 min on a daily basis for 12 weeks. After 12 weeks of LLLT and LED device use, there were significant improvements in redness, elasticity, and hydration of the scalp. Additionally, hair luster and tensile strength were improved. A remarkable decrease in total shed hairs was observed in all subjects at 4, 8, and 12 weeks without any serious adverse event. Combined light therapy using LLLT and LEDs proved to be an effective treatment for reducing hair loss and improving scalp condition.

본 연구에서는 655 nm에서 저출력 레이저와 625 ± 5 nm와 850 ± 10 nm에서 파장을 방출하는 LED를 이용한 복합 광선 요법이 탈모 및 두피에 나타나는 효능을 조사하고자 하였다. 이번 연구에는 총 33 명의 시험대상자가 등록되었다. 각 시험대상자는 Low-level laser therapy (LLLT)와 light-emitting diode (LED) 기기를 매일 10 min 씩 12 주간 두피와 모발에 사용했다. LLLT와 LED 기기를 사용한 지 12 주 후, 두피의 붉은기, 탄력, 수분 함량에서 상당한 개선이 있었으며, 모발의 윤기와 인장 강도, 탈락 모발 수가 개선되었다. 시험대상자가 시험 기기를 사용하는 기간 동안 특별한 피부 이상반응에 대한 보고는 없었다. LLLT와 LED를 이용한 복합 광선 요법은 탈모와 두피 상태 개선에 효과적인 요법임이 입증되었다.
