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 daily oral finasteride may increase hair count and improve hair appearance assessments in men with androgenetic alopecia, but it also appears to raise the risk of sexual dysfunction.

This study found that blocking androgen receptors inhibits testicular descent in rats more effectively during the early stages of gubernacular outgrowth than inhibiting 5a-reductase.

This review discusses the roles of phytohormones like auxin and ethylene in regulating root hair growth and development in plants, but it reports no new experimental results.

This study identified a novel homozygous EDNRA variant linked to Oro-Oto-Cardiac Syndrome and showed that EDNRA signaling is essential for normal craniofacial and cardiovascular development.

This study identified genetic variations associated with black and white wool color in Gangba sheep, enhancing understanding of wool color genetics and aiding selective breeding for specific wool colors in Tibetan sheep.

This paper provides a comprehensive review of melanocytes' roles in skin biology, focusing on their pigmentation and immune functions, and suggests potential research opportunities for preventing and treating skin disorders.

This study's network meta-analysis reported that botulinum injection combined with red laser and topical minoxidil is most effective for increasing hair density in androgenetic alopecia when using low-level laser therapy.

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 veterinary study, uveodermatological syndrome in dogs was reported to cause skin depigmentation, alopecia, and eye issues such as granulomatous panuveitis, which leads to complications like cataracts and glaucoma; while immunosuppressive therapy often helps, recurrence and treatment side effects challenging therapeutic management.

This study identified six species of ectoparasitic insects infesting domestic goats in Bulgaria, with Linognathus stenopsis being the most prevalent across the surveyed farms.

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 research found evidence of inflammatory involvement in androgenetic alopecia, with higher deposition of certain immune components in the scalp of affected patients compared to those without baldness.

This review discusses recent evidence on how night-shift work affects the circadian system, sleep, and alertness in shift workers, and reports no clinical results; potential impacts on health are considered.

This study observed that darker hair is typical in wetter regions for the Indriidae family, while within Propithecus, dark black hair is common in colder forests, suggesting evolutionary adaptations to environmental pressures.

This study found that irradiating human adipose-derived stem cells with green OLEDs enhanced their wound healing capability and increased cell proliferation, migration, and adhesion in preclinical models.

In this study, the researchers found that cholinergic signaling via M4 muscarinic receptors influences hair growth, with enhanced elongation observed upon activation with bethanechol, highlighting its potential role in hair biology using mouse models.

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 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.

This review discusses new research on the role of retinoids in skin and hair health and reports no clinical results.

This study found that blue laser irradiation reduced ATP levels and cell viability in mouse skin by increasing oxidative stress through the production of reactive oxygen species.

Photobiomodulation did not significantly improve hair density in dogs with alopecia X.

This study investigated the role of the ABCA4 gene in human keratinocytes and hair follicle stem cells and found that silencing the ABCA4 gene increases the harmful effects of all-trans-retinal on hair follicle stem cells.

This review synthesizes research on solar radiation's multifaceted effects on skin and recent advancements in sunscreen technology, including formulation, testing methods, and the use of AI, to inform future sun protection product development.

This study examines the effects of excessive or prolonged exposure to blue light on retinal function and highlights its potential health implications, noting that both photoreceptor and intrinsically photosensitive retinal ganglion cells (ipRGCs) are particularly sensitive to blue wavelengths.

This review discusses the state-of-the-art in photobiomodulation therapy for oral and dental applications and emphasizes the need for education, training, and addressing logistical issues for its routine use.

This review explores the detrimental effects of sunlight on the skin’s circadian rhythm and photodamage, noting the potential of natural cosmeceuticals to influence this rhythm, but reports no new results.

This collection of reviews, edited by Ken Lukowiak and Janis Weeks, explores diverse sensory systems across species, including olfaction, echolocation, magnetoreception, and visual adaptations, without presenting new experimental results.

This review explores melatonin's role in hair follicle cycles and its molecular mechanisms that enhance antioxidant capacity and modulate gene expression, offering potential strategies to improve cashmere production and treating human alopecia, according to the authors.

This study highlights the loss of hair-type keratin genes in cetaceans compared to terrestrial mammals, suggesting a potential adaptive role linked to their hairless phenotype and habitat changes.
