LED light helps human hair root cells grow and move by activating certain cell pathways.

This study found that NB-002 demonstrated clear antifungal activity and clinically significant nail clearing in subjects with distal subungual onychomycosis and ≤50% nail involvement, compared to a vehicle treatment.

This article discusses hormonal mechanisms underlying androgenetic alopecia but does not report any new findings; it reviews the roles of dihydrotestosterone and available FDA-approved treatments.

This editorial reviews how photobiomodulation therapy might effectively treat both hyperpigmentation and depigmentation skin disorders, but reports no new clinical results.

This study suggests that pulsed wave photobiomodulation could be a promising treatment for androgenetic alopecia by enhancing dermal papilla cell function through specific light parameters, particularly frequency.

This randomized controlled trial reported that light-emitting diode therapy significantly reduced ecchymosis and edema and accelerated wound healing in patients during the first two weeks following rhinoplasty, without any adverse effects.

This study found that LED light irradiation induced proliferation and migration of human outer root sheath cells, potentially through the stimulation of the Wnt/β-catenin and ERK signaling pathways.

This review discusses the mechanisms, scientific support, and FDA clearance of photobiomodulation mask devices but reports no new research findings.

In this study involving two volunteers with Androgenetic Alopecia, phototherapy using red and blue wavelengths promoted benefits, as observed through photographic and trichoscopy comparison after 12 weekly sessions.

In this study, researchers observed that red and red-orange LED light therapy stimulates nitric oxide production and decreases dihydrotestosterone synthesis in cell models, suggesting a potential mechanism for using light therapy to treat androgenetic alopecia.

This study found that photobiomodulation-irradiated conditioned medium from human adipose-derived stromal cells enhanced hair growth in mice, suggesting its potential as a treatment for hair loss by increasing growth factor secretion.

In this study, both red and blue light phototherapy were found to increase hair density, reduce the central parting, and boost the number of terminal hairs in individuals with Androgenetic Alopecia, over 12 weeks of treatment.

This study found that conditioned medium from photobiomodulation-irradiated adipose-derived stromal cells enhanced hair growth in a mouse model of hair loss more effectively than non-irradiated medium, suggesting potential for treating alopecia by boosting growth factor secretion.

This study suggests that LED light may promote the proliferation of human dermal papilla cells through the activation of specific signaling pathways.

This study found that isolated red light may serve as an alternative for photo-immunotherapy without additional photosensitizers, as it did not reduce keratinocyte differentiation markers or increase photo-oxidative damage, unlike treatment with IL-4 or UVA1/blue light.

This case report describes the first use of photobiomodulation therapy with a continuous wave red laser (660 nm) as monotherapy for alopecia areata, resulting in significant hair regrowth within 7 days, though further research is needed for conclusive evidence.

This review evaluates photobiomodulation's diverse clinical uses in sports and medicine, reporting physiological modulation and potential therapeutic benefits, but emphasizes the importance of precise dosimetry for success.

This study found that low-level light therapy significantly increased hair density and diameter in androgenetic alopecia patients compared to a sham device, suggesting it could be an effective treatment option.

This review discusses the applications of low level laser therapy (LLLT) in wound healing, pain reduction, and treating various conditions, but reports no new clinical results; the authors highlight the need for randomized controlled trials for serious diseases.

This review suggested that low-level light therapy using red/near-infrared light could be a safe and effective treatment for various skin and hair conditions, though more robust trials are needed to solidify its clinical utility.

This review discusses the effectiveness of non-thermal, non-ablative devices like light-emitting diodes in treating various skin and hair conditions but reports no new clinical findings.

In this review, the researchers highlight LED therapy as an emerging and safe treatment for skin inflammatory conditions, aging, and hair growth disorders, noting its integration into dermatological practice but emphasizing the need for more controlled studies to confirm its efficacy.

This study found that 655-nm red light with LED enhanced hair shaft elongation and reduced catagen transition in human hair follicles in vitro by activating the Wnt/ß-catenin signaling pathway.

This article reviews the growing trend of at-home laser and light devices for treating conditions like acne, hair removal, and psoriasis, emphasizing their popularity and the need for cautious use but reports no new clinical results.

This review concluded that LED-based photobiomodulation is generally safe and effective for certain dermatologic conditions, though consumer devices often show less efficacy compared to professional systems.

This study found that near-infrared LED therapy enhanced ATP synthesis, reduced reactive oxygen species, and promoted collagen production and hair growth more effectively than white LEDs in human skin cells and a photoaging mouse model.

This review discusses the application of low-level light therapy for hair loss treatment, particularly androgenetic alopecia, and reports no new clinical results; the authors suggest consideration of light source characteristics and potential pros and cons.

This review found that many low-level light therapy studies report beneficial effects but often fail to provide adequate measurement details, affecting the reliability and repeatability of the research.

This review discusses the applications and advantages of LED-based photobiomodulation therapy for dermatological and cosmetic purposes but highlights existing challenges and health concerns while exploring future perspectives.

In this randomized, double-blind trial, researchers observed that low-level laser therapy led to significantly greater hair regrowth on treated areas compared to a sham treatment in patients with androgenetic alopecia over 24 weeks, suggesting it as a potentially effective and safe option.
