TLDR Low-Level Light Therapy (LLLT) is a safe and effective method for skin rejuvenation, acne treatment, wound healing, body contouring, and hair growth, but more well-designed trials are needed for confirmation.
The document discusses the clinical applications of Low-Level Light Therapy (LLLT), or photobiomodulation, in various fields including skin rejuvenation, acne vulgaris, wound healing, body contouring, and androgenic alopecia. LLLT uses red/near-infrared light energy to enhance cellular processes and reduce oxidative stress. Clinical trials suggest it is a safe and effective method for these applications, but the quality of evidence needs improvement due to methodological flaws and small patient cohorts. In a study with 6 volunteers, LLLT increased dermal fibroblast activity and metabolic activity. A trial with 107 acne patients showed significant improvement with a combination of blue and red light. A meta-analysis of 11 trials with 667 subjects showed LLLT improved hair density and thickness. However, the document concludes that more well-designed, independent clinical trials are needed to answer unresolved questions.View this study on academic.oup.com →
LLLT devices for hair loss need more research to define proper guidelines.
Low-level laser therapy significantly increases hair density in adults with hair loss, with low-frequency treatment being more effective.
Low-level light therapy safely improves hair coverage, thickness, and count in androgenetic alopecia patients.
Low-level laser therapy effectively treats female hair loss, increasing hair count by 51%.
The laser scanner device was more effective at increasing hair density than the laser hat in treating androgenic alopecia.
Laser device increases hair density, safe for treating hair loss in men and women.
Male pattern baldness may be caused by scalp pressure on hair follicles, which increases with age and leads to a cycle of hair loss. This process is not directly determined by genes.
Low-level light therapy safely improves hair growth and thickness for androgenetic alopecia.
HairMax LaserComb® effectively promotes hair growth and stops hair loss in males with androgenetic alopecia, with no serious side effects.
