This study found that LEDs at specific wavelengths may improve antifungal performance and promote hair growth by activating scalp cells without inducing inflammation compared to a non-irradiated group.

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.

In this study, 308-nm excimer light therapy showed significant effects in some patients with treatment-resistant alopecia universalis, suggesting it as a potential alternative therapy.

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 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 article reviews the basics of hair follicle biology, laser/tissue interactions, and hirsutism and hypertrichosis causes, discussing the long-pulsed alexandrite laser's role in hair reduction without reporting new clinical results.

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 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.

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 study evaluated an 808-nm diode laser at different fluences for permanent axillary hair removal in Korean women and found that high-fluence treatment (14 J/cm2) effectively reduced hair density and thickness, with no significant difference in comfort compared to lower fluences.

In this study, patients with androgenic alopecia who underwent 10 sessions of 1540-nm fractional erbium glass laser treatment over 5 months experienced significant improvements in hair density and thickness, with no major safety concerns reported.

In this study, both 1565-nm non-ablative fractional laser and long-pulsed 1064-nm Nd:YAG laser effectively reduced enlarged facial pores, with no significant difference in efficacy and minimal side effects, though the Nd:YAG laser had less severe side effects.

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 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 pilot study, researchers observed that low-intensity laser radiation at 445±40 nm increased the temperature of gingival tissues in Wistar rats by 8.37°C without exceeding the safety threshold, suggesting potential for clinical trials.

In this study, applying 1% or 5% Curcuma aeruginosa essential oil lotion to the underarm for 10 weeks significantly slowed hair growth and brightened skin in young women, with no adverse effects reported.

This study observed that exposure to different wavelengths of light affects opsin and clock gene responses in skin cells, suggesting potential therapeutic approaches using photobiomodulation for dermatological conditions like psoriasis and wound healing.

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.

In this study, periodic exposure to red light in aged mice led to increased histone acetylation and activated mitochondrial fatty acid oxidation, which collectively mitigated cellular aging by modulating metabolism, inflammation, and gene expression.

This review concluded that oral finasteride for men and topical minoxidil for both genders have the most evidence supporting their effectiveness and safety for treating androgenetic alopecia.

This abstract discusses the broad scope of dermatology and aesthetic procedures, highlighting their significant multidisciplinary evolution within the health sciences, but it does not report specific study results.

This research concluded that the novel hydrogel PlacMA, derived from human placenta and curable by visible light, shows promise for cell culture and tissue engineering applications due to its tunable properties.

This study describes a protocol for inducing endogenous reactive oxygen species in mouse skin, which stimulates tissue regeneration and promotes burn healing and hair follicle growth.

This study provides evidence-based recommendations for the off-label use of topical vitamin D in treating certain skin conditions, but highlights the need for higher quality studies for further validation.

This review discusses the unique dermatologic needs and conditions affecting women of color, noting specific skin and hair conditions but reports no clinical results.

This review explores the current treatments for different types of alopecia, emphasizing the need for well-designed clinical trials and highlighting that most therapies are used off-label, as only androgenetic alopecia has FDA-approved drugs.

This review reports on the dual aspect of fullerene in skincare, highlighting its beneficial antioxidant properties as well as potential toxicity and skin cell reactions, while identifying areas for future research.

In this study, researchers found that Asian hair contains more integral lipids than European or African hair, which may protect it better from UV-induced damage.

This article reviews practical approaches for managing dermatologic conditions in patients with skin of color and reports no new clinical findings.
