Abstract
|
|
|
Objectives : The purpose of this study is to determine the safety and efficacy of low level laser.
Methods : We searched 11 electronic databases(Pubmed, CAJ, EMBASE, Medline, Cochrane Library, KMBASE, KISS, KISTI, NDSL, RISS, Oasis) up to March 2019. We included randomized controlled trials(RCTs) using low level laser for alopecia. The methodological quality of each RCT was assessed by the Cochrane risk of bias tool.
Results : 8 RCT studies were eligible in our review. The meta-analysis of 2 studies showed favorable results for the use of low level laser with minoxidil 5% than minoxidil 5% and 6 studies showed favorable results for the use of low level laser than placebo light. The results of meta-analysis showed that low-level laser has an efficacy on alopecia. There were no serious side effects or adverse effects. High risk of bias were observed in all studies.
Conclusion : Now limited evidence is available to support low level laser for alopecia and further well-designed RCTs should be encouraged.
