This review discusses the modest efficacy of home-use laser and light devices for conditions like hair removal and acne, noting limited evidence and a lack of robust trials.

This study found that low-level laser therapy may have promising effects on hair regrowth in dogs with noninflammatory alopecia, with most animals showing improvement after treatment.

This review discusses five popular resurfacing technologies for facial rejuvenation, highlighting their role in achieving smoother, healthier, and younger-looking skin, and reports no new clinical results.

This review highlights that laser and light treatments could serve as safe and effective alternatives to current therapies for alopecia areata, with the excimer laser showing positive results, though further randomized controlled trials are necessary to establish optimal treatment protocols.

This study found that low-level laser treatment may promote hair regrowth in mice by activating the Wnt10b/ß-catenin pathway and inducing the anagen phase of hair follicles.

This review assesses low-level laser therapy in plastic surgery and reports that it may improve flap survival and burn scars, but lacks efficacy for venous ulcers, alopecia, and skin aging.

This study reviewed clinical trials and found that low-level laser therapy significantly increased hair diameter or density in both men and women with pattern hair loss compared to a sham device, though the involvement of industry relationships in some studies suggests cautious interpretation.

This study found that 1,550-nm Er:Glass fractional laser treatment increased hair density and shaft diameter in patients with androgenetic alopecia, but did not up-regulate Wnt10A and IGF-1 mRNA expression.

This study observed that combining nonablative fractional laser treatment with topical minoxidil led to hair regrowth in Chinese alopecia areata patients, noting complete regrowth in some patients and no relapse in the majority at a one-year follow-up, without reported side effects.

This study evaluated low-level laser therapy for treating Androgenic alopecia and suggested it may effectively stimulate hair growth and improve patient satisfaction, although more efficient treatments are needed.

This study found that adding low-level laser therapy to conventional treatment for canine acral lick dermatitis significantly increased hair growth compared to conventional therapy alone, but did not significantly reduce licking behavior.

This study reviews the mechanism and potential treatment roles of low-level laser therapy for immune-mediated skin diseases, reporting no new clinical results.

In this study, a 3-month treatment with a 2940 nm Er:YAG laser, combined with conventional therapy, effectively reduced microfibrosis around hair follicles and increased hair growth in the anagen stage among 85 men with androgenetic alopecia.

This article discusses the use of low-level laser therapy for hair regrowth in men and women but reports no new clinical results; it reviews types of lasers and evidence from animal and human studies.

This review discusses the critical parameters for MALDI IMS sample preparation in skin analysis and highlights its applications in wound healing, neoplasia, and infection research, but reports no new clinical results.

This study found that combining micro-needling, low-level laser therapy, and autologous non-activated platelet-rich plasma increased hair density in patients with androgenic alopecia over the treatment period.

This study found that nano-sized lipid particles improved the skin accumulation and retention of dexamethasone compared to a base cream, suggesting potential benefits for inflammatory skin disease treatment.

This study concluded that ablative fractional lasers may induce hair regrowth in mice by activating the Wnt/β-catenin pathway.

This study found that 675 nm laser treatment improved androgenetic alopecia in Indian patients, resulting in significant increases in hair count, density, and thickness after 14 sessions, enhancing the anagen phase and other hair-related parameters.

In this study, 14 sessions of 675 nm laser stimulation significantly improved hair count, density, and thickness in Indian patients with androgenetic alopecia, with an increase of around 17% in hair parameters over four months.

Minoxidil increases blood flow in balding scalps, possibly reversing hair loss.

This study found that treatment with a 1550 nm fractional erbium–glass laser increased hair density and thickness in women with female pattern hair loss, suggesting it may be an effective and safe option.

This review found that most studies support the effectiveness and safety of using hyaluronic acid fillers and laser treatments together for facial rejuvenation, but highlights that the evidence is limited to small, nonrandomized studies and additional research is necessary.

This abstract describes the use of lasers in hair transplantation for creating recipient sites and enhancing hair growth but reports no new findings.

In this study, the researchers demonstrated an automatic alignment method for beams in an electron pumped excimer laser system that achieved high precision and accuracy, with a reported alignment accuracy of 0.63μrad.

This letter to the editor reports no new research findings.

This review discusses the benefits and drawbacks of low-level laser therapy for various non-surgical conditions based on existing literature, but reports no new clinical findings and suggests further research is needed.

This study found that the 2,940 nm erbium: YAG laser may promote hair growth in C57BL/6 mice by speeding up transitions in the hair cycle and increasing hair follicle numbers.

In this interventional study on female-pattern hair loss, researchers found that fractional CO2 laser therapy alone improved hair growth, as evidenced by increased hair count, thickness, density, and patient satisfaction compared to saline controls. However, the precise mechanisms behind these effects require further investigation.

This review discusses clinical studies on low-level laser therapy for various types of hair loss and suggests it may be promising for those unresponsive to conventional treatments, but reports no new clinical results.
