Light can be used to stimulate ear hair cells, improving speed and consistency over previous methods.

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 at 655 nm significantly increased hair counts in males with androgenetic alopecia.

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 study found that monochromatic excimer light achieved complete remission in over 50% of plaque psoriasis cases and various levels of improvement in other skin conditions, including vitiligo and mycosis fungoides.

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.

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 study found that red light accelerated the transition from the resting to growth phase in hair follicles faster than green and blue light in mice, suggesting it may stimulate hair growth.

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.

Continuous light exposure in rats leads to PCOS-like symptoms and suggests sleep habits might affect the disorder's development.

This review concludes that current clinical and preclinical evidence does not indicate oncologic safety concerns linked to photobiomodulation therapy for skin rejuvenation, including no clear evidence of increased cancer risk.

This review evaluates the potential benefits and mechanisms of blue light therapy for skin conditions like atopic dermatitis and acne, but highlights the need for further research on safety and clinical protocols.

In this study, blue light therapy at a specific wavelength increased hair density and shaft width in 90% of patients with androgenetic alopecia after 10 weeks.

This study demonstrated that a new technology combining microneedle patches, stem cell exosomes, and light therapy effectively promoted hair regrowth in animal models within 7 days compared to conventional treatments.

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 discusses how the balding scalp's exposure to UV and near-infrared light may accelerate aging, with changes detectable under ultraviolet light; it presents no new clinical findings.

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 ultraviolet light-enhanced visualization can detect subtle skin changes linked to carotene and vitamin A deficiency, which improved with dietary correction in deficient individuals.

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.

This review discusses the role of vitamin D metabolism in skin immunity and wound healing but does not present new results, highlighting the need for further research into its therapeutic applications.

This case report describes a child with hypopigmented mycosis fungoides successfully treated with UVA1 light therapy.

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 reports pseudopili annulati in a dark-haired Chinese girl, identifying the unique appearance and structural characteristics of her hair without finding abnormalities in the cuticle and cortex.

This study analyzed clinical and histological reports and concluded that blue light therapy is safe for human skin, with potential photoprotective effects against UV irradiation due to its impact on skin pigmentation mediated by Opsin-3.

This study suggests that Medicago sativa extract, combined with UVA light, may enhance pigmentation in hypopigmented skin and hair, offering potential treatment for vitiligo.

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 study reports cases of androgenetic alopecia patients with depigmented macules on sun-exposed scalp areas, suggesting potential ultraviolet-induced scalp leukoderma not covered in existing dermatology texts.

This review compares the CO2 and Er:YAG laser treatments for acne scars, noting that while CO2 lasers offer deeper tissue penetration for severe scars, Er:YAG lasers pose a lower risk of post-inflammatory hyperpigmentation, and recommends personalizing treatments and considering combination therapies.
