This study observed that LED therapy improved hair regrowth and reduced hair loss in patients with post-COVID telogen effluvium, with or without androgenetic alopecia, compared to those who did not receive LED treatment.

A thorough assessment and combined treatment are crucial for managing complex alopecia, especially in patients with skin of color.

This review reported that alopecia prevalence and psychosocial impacts vary significantly among migrant and ethnic minority communities due to diverse genetic, environmental, and cultural factors, highlighting needs for culturally competent care and stigma reduction to address disparities and improve access.

This review examines the hormonal causes of hair loss, noting how androgen excess can lead to follicle miniaturization and linking estrogen deficiency and thyroid dysfunction to common alopecia types. It further discusses hormonal treatments such as finasteride, dutasteride, and spironolactone.

Oral Vitamin D can improve hair density and reduce hair loss in Telogen Effluvium patients.

In this observational study, nine out of ten patients developed Telogen Effluvium after mild COVID-19 symptoms, with hair shedding starting on average 73 days following infection.

This study found that male patients with hair loss often had lower levels of vitamins D and B12, suggesting these deficiencies should be tested for in treatment evaluations.

In this study, women with diffuse hair loss reported that Proteoglycan Replacement Therapy with Nourkrin® improved hair growth and appearance, boosting their confidence and satisfaction with the treatment.

This study found that injecting mouse hair follicle-derived mesenchymal stem cells (moMSCORS) into C57BL/6 mice reduced the incidence and severity of type 1 diabetes by modulating immune responses, suggesting potential for therapeutic use due to their immunosuppressive effects.

This study suggests that controlling light exposure can influence cashmere growth by triggering hair follicles to enter their active growth phase sooner, potentially involving the CSDC2 gene as a key regulator.

This study found that low temperatures and nitrogen deficiency trigger root hair elongation through a molecular mechanism involving the receptor kinase FERONIA and the TOR Complex 1.

This study found that glucose starvation and hypoxia are physiological triggers of ER stress in in vitro differentiated adipocytes, rather than high concentrations of saturated fatty acids, cholesterol, or proinflammatory cytokines.

This study utilized a mouse model of traumatic brain injury to reveal that acute neurotrauma triggers widespread lipid metabolism reprogramming and storage lipid accumulation in microglial and monocyte populations, leading to lysosomal dysfunction, inhibited autophagy, and exacerbated inflammation through a pathological feedback loop.

This study suggests that mitochondrial dysfunction might contribute to the pathogenesis of Lichen planopilaris by triggering a metabolic shift that leads to chronic inflammation and hair follicle damage.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

This article reviews the concept of telogen effluvium and emphasizes the importance of identifying triggers and using diagnostic investigations to determine the cause of hair loss, without reporting new results.

This review article discusses studies showing that extracellular nucleic acids play a role in tissue regeneration by triggering sterile inflammation through endosomal toll-like receptor activation, but notes that the regulatory transition from inflammation to proliferation phases remains incompletely understood.

This study found that feeding aged mice a probiotic yogurt induced changes leading to thicker, healthier fur, suggesting a bacteria-triggered interleukin-10-dependent mechanism that mimics signs of youth and reproductive fitness.

This study created a novel classification for dermatological and cosmiatric changes caused by cancer treatments, categorizing them as triggered, exacerbated, or unrelated to the treatment.

In this overview of COPD exacerbations, it was reported that these events, often triggered by respiratory viruses, not only worsen symptoms but also increase the risk of cardiac events, highlighting the importance of early detection and prevention strategies such as vaccinations and new biologic therapies.

This study observed that PAD type III and trichohyalin are expressed earlier than their deiminated form during the first and second hair cycles in rat hair follicles, indicating a potential additional factor is involved in triggering deimination.

This narrative review identifies telogen effluvium as a growing concern linked to weight-loss interventions, such as GLP-1 receptor agonists and bariatric surgery, attributing hair loss to systemic and metabolic stress rather than permanent hair follicle damage.

This study reviews the causes, mechanisms, and treatments for thin endometrium, highlighting multiple contributing factors such as hormonal influences, long-term oral contraceptive use, and uterine inflammation, while noting unclear mechanisms in promising therapeutic strategies like pharmacological treatments and regenerative medicine approaches.

In this study, researchers observed no significant association between hijab use and telogen effluvium among female medical students, despite a relatively high incidence of hair loss in this population.

This review explores whether SARS-CoV-2 could trigger or worsen α-synucleinopathies, like Parkinson's disease, by affecting α-synuclein misfolding and aggregation, potentially linking COVID-19 with the development of parkinsonism-like symptoms.

This study found that multimetal starvation by the immune protein calprotectin triggers unique regulatory responses in Pseudomonas aeruginosa, beyond those seen with individual metal shortages.

This study observed that among male patients who experienced telogen effluvium after platelet-rich plasma treatment for androgenic alopecia, there were elevated levels of TNF-α, androgen receptors, and altered 5α-reductase gene expression, suggesting these factors as potential contributors to this unintended outcome.

Thyroid-stimulating hormone affects hair follicles but doesn't change hair growth or color.

This study found that sleep deprivation in mice can trigger prostatitis by activating the cGAS-STING pathway due to reduced levels of dihydrotestosterone and melatonin, resulting in a pro-inflammatory environment, while recovery sleep can mitigate these effects.

This study found that low-level laser treatment may promote hair regrowth in mice by activating the Wnt10b/ß-catenin pathway and inducing the anagen phase of hair follicles.
