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 review discusses low-level light therapy for androgenetic alopecia and female pattern hair loss, noting minimal clinical evidence on its efficacy and the need for more controlled studies.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This study found that Piezo2 channels are primarily located on sensory axon membranes in mechanosensory end organs, supporting a model where mechanical stimuli activate Aβ RA-LTMR neurons via axon protrusions.

HEV light can harm or help skin and scalp, so safe exposure guidelines are needed.

This study found that human hair follicle dermal papilla cells and keratinocytes self-assembled differently in 3D spheroid co-cultures, providing insights into cell distribution and organogenesis during skin regeneration.

In this article, researchers explored how blue light exposure affects the scalp and hair follicles, highlighting oxidative stress and hair growth disruptions, while emphasizing the importance of protective strategies like antioxidants and limiting light exposure.

This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.

This study found that low-level laser therapy significantly increased hair growth in women with androgenic alopecia, achieving a 37% greater increase in hair counts compared to placebo.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

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

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.

This study found that topical application of mitochondrial electron transport chain inhibitors stimulated hair follicle stem cell activation and hair regrowth in aged mice by promoting lactate production.

This review suggests that low-level light therapy can promote hair growth in patients with androgenetic alopecia, but more research is needed to standardize treatment parameters and assess long-term safety and efficacy.

This article explores the potential of photobiomodulation for coronary health, suggesting protective effects after heart attacks and in inaccessible ischemic heart conditions, but presents no new clinical results.

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 review highlights evidence supporting the potential of blue light therapy as a non-invasive treatment for managing skin and hair conditions by modulating interactions between the skin microbiome and its host.

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.

Researchers developed a new way to measure gene activity in single hair follicles and found that a specific gene's activity changes with different amounts and times of treatment.

This review discusses the potential mechanisms and evidence supporting low-level laser therapy for stimulating hair growth in men and women, while noting its safety and effectiveness but needing further study on specific parameters.

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.

In this study, low-level laser therapy showed no statistically significant improvements in hair growth measures, despite some patients experiencing increases in terminal hairs and shaft diameter.

This review highlights the potential of near-infrared light therapy to improve metabolic, antioxidant, and cognitive functions without adverse effects, and supports its use for visual and neurological conditions through molecular and cellular mechanisms, as reported in this source.

This review discusses the potential of repeated low-level red-light therapy to inhibit myopia progression through metabolic effects, highlighting its molecular and cellular impact, but reports no new clinical results.

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.

In this study, researchers developed a new photoactivatable Cre recombinase mouse model, DiLiCre, which allows precise light-induced genetic modifications and cell tracing, demonstrating its effectiveness for advancing biological and biomedical research.

In this study, low-level light therapy using a new helmet-type device significantly increased hair density and thickness in patients with androgenetic alopecia, showing no adverse events or side effects, suggesting it may be a safe and effective treatment option for both sexes.

This study observed that adding low-level light therapy with the GentleWaves® device to Minoxidil significantly boosted hair regrowth in men with androgenetic alopecia by reducing scalp inflammation.

This review concluded that near-infrared and red light photobiomodulation shows potential for certain ocular conditions like age-related macular degeneration and dry eye disease, but clinical evidence is still mixed and insufficient to establish it as a standard therapy.
