This study demonstrated that visible light lightens blond hair more effectively than ultraviolet light, attacking melanin granules directly, whereas ultraviolet light primarily damages other hair tissues following washing.

This study analyzed how oxidative hair dye leaches from pigmented and nonpigmented hair during wash cycles, finding that melanin influences the dye deposition and leaching processes.

This study observed that silver nanoparticles synthesized using Laurus nobilis leaf extracts significantly inhibited protein denaturation and membrane stabilization in vitro, suggesting potential as a basis for novel antiarthritic drugs.

This study reported that silver nanoparticles synthesized from jackfruit leaf extract demonstrated broad-spectrum antimicrobial properties, with a formulated gel showing greater efficacy against E. coli compared to a commercial silver nitrate product.

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 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 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.

In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

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 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 randomized trial found that diode laser achieved more favorable long-term hair removal outcomes but induced more discomfort and transient adverse effects compared to intense pulsed light in women with Fitzpatrick skin types I-IV.

Low-Level Laser Therapy can stimulate healing and cell function, potentially leading to wider medical use.

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.

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.

This study in male rats identified a unique type of mechanoreceptor, the club-like ending, which responds only to touch and not to self-motion during whisking, contrasting with other receptors that show mixed selectivity.

In this study, more than 25% of children experienced axial length shortening greater than 0.05 mm/year following repeated low-level red-light therapy.

This review discusses the role of antioxidants in managing oxidative skin damage and reports no new results, emphasizing the need for understanding their mechanisms, limitations, and risks for safe use.

This review discusses the challenges in selecting optical parameters for photobiomodulation studies on hair regrowth and wound healing, reporting no new clinical results and recommending more rigorous, standardized research approaches.

This study found that higher concentrations of copper (II) ions in human hair increase protein oxidative modification, contributing to hair damage regardless of UV exposure and pigmentation level.

This study found that combined intense pulsed light and low-level light therapy significantly improved ocular surface outcomes and quality of life for patients with meibomian gland dysfunction and dry eye disease.

In this study, ceruloplasmin and keratin 4 were identified as markers that differentiate between growing and resting phases in cashmere goat hair follicles, with keratin 4 being a potential marker for the onset of a new hair cycle.

This study found that using the OptoTrkA system to control TrkA activity with blue light enhanced proliferation, migration, and differentiation of hair-follicle-derived stem cells into neuronal and glial cells.

This study found that using an LED array with an 863 nm wavelength delayed tumor development and reduced systemic inflammatory cytokines in DMBA/TPA-induced mouse skin tumors, suggesting potential but limited benefits of light therapy.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.
