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

This study reported that horses with pituitary pars intermedia dysfunction had improved coat condition, advanced shedding, and better quality of life when treated with blue light masks.

This article reviews the versatile applications of red and infrared light therapy, reporting that these treatments can enhance skin health by modulating cellular processes such as RNA and protein synthesis, oxygen consumption, and reducing oxidative stress and inflammation.

This study observed that exposing human hair keratins to heat or UV treatments led to modifications in cysteine residues, disrupting crucial disulphide bonds and potentially reducing the structural integrity of hair similar to prolonged styling or sunlight exposure.

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.

In this study, researchers observed that inhibiting myosin light chain kinase in hair cells reduced stiffness and oscillation in bullfrog hair bundles and increased hearing thresholds in mice.

This study observed that supplementing buffalo calves with a mineral mixture alone or combined with Nigella sativa seeds improved skin conditions and hematobiochemical parameters in calves suffering from parakeratosis, which is primarily due to zinc deficiency.

This narrative review explored how blue light therapy may offer therapeutic benefits for various skin disorders by affecting microbial activity and immune responses, promoting hair growth, and aiding skin rejuvenation and healing.

This study developed a NIR light-triggered NO-releasing hydrogel that promotes angiogenesis, repairs damaged dermal papilla cells, reduces inflammation, and improves the nutrient supply and follicular environment in animal models, offering a promising treatment strategy for androgenic alopecia.

This study observed that pooled analysis of LED caps increased hair density in patients with androgenetic alopecia compared to sham, achieving 28.5 more hairs per cm².

This study suggests that a combination of blue light photobiomodulation and biomimetic peptide infiltrations may effectively increase hair density in patients with androgenetic alopecia.

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 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 study found that combining red light therapy with oral beta-carotene significantly improved photoaging treatment outcomes compared to red light therapy alone, with Group A showing a 56.12% reduction in photoaging scores over 12 weeks versus 44.78% in Group B.

This study evaluated a novel hand-held low-level light therapy device for treating mild-to-moderate acne, finding it significantly reduced inflammatory lesions and moderate acne severity without severe adverse reactions, while also reducing Cutibacterium acnes viability in vitro.

In this study, both excimer light and low level light therapy were found to be safe and effective for treating alopecia areata, with excimer light showing better and more sustained improvement.

This study reported that using a Cutera Xeo laser with specific probes may help treat rosacea symptoms like diffuse facial erythema and telangiectasias, with some risks like bruises and hypopigmentation.

This study found that exposure to red LED light may improve fibre quality and hair follicle development in Angora rabbits, potentially due to increased melatonin secretion.

In this study, polarized light therapy increased hair regrowth in patients with alopecia areata compared to those who received only minoxidil.

This study suggests that low-dose blue light (453nm) may positively affect hair growth by interacting with the receptors CRY1 and OPN3 in hair follicle cells.

In this study, low-dose 453 nm blue light appeared to enhance hair growth by interacting with specific photoreceptors in the outer root sheath cells.

This study found that while 450nm blue light can inhibit collagen and induce oxidative stress in dermal fibroblasts, 850nm near-infrared light may enhance metabolic activity without causing oxidative damage, suggesting potential for tailored light therapies in skin treatments.

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

Polarizing light microscopy can easily and reliably diagnose congenital keratinizing disorders like Netherton syndrome.

In this study, LED irradiation was found to promote hORSC proliferation and stimulate the Wnt5a/β-catenin and ERK signaling pathways, suggesting a potential mechanism for hair growth.

This study found that intralesional triamcinolone was the most effective treatment for achieving over 50% hair regrowth in alopecia areata patients, especially those with single patches.

This study evaluated 308 nm excimer light therapy for alopecia areata but the abstract does not provide specific clinical results or conclusions.

This study observed that excimer light therapy, intralesional triamcinolone, and topical 5% minoxidil all had differing levels of effectiveness in treating alopecia areata, with variable results noted among treatments.

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.
