This study demonstrated that stress-derived neurosteroid THDOC shifts from inhibiting to activating the HPA axis under stress, presenting potential therapeutic targets for stress-related disorders.

This study characterized the stress-strain properties of the human scalp and found that its stiffness increases significantly with load, providing valuable insights for planning scalp surgery procedures.

This study introduces the concept of a "gut–brain–skin axis" where ingesting a specific Lactobacillus strain in mice may reduce stress-induced skin inflammation and hair growth inhibition.

This study found that upcycled postbiotic cell-free supernatants from Limosilactobacillus fermentum MG901 and MG4237 protected human dermal papilla cells from oxidative stress, enhancing wound-healing capacity and mitochondrial function, suggesting potential as a sustainable cosmetic ingredient for hair loss alleviation.

This study found that finasteride impaired stress reactivity and reduced exploratory and impulsive behaviors in rats, potentially by altering the hypothalamus-pituitary-adrenal axis function.

This study found that oral probiotic supplementation over 12 weeks may improve hair growth, skin condition, metabolic health, and stress responses in Chinese adults with hair loss and a high risk of metabolic syndrome.

This study found that acute stress can cause rapid hair loss by triggering necrosis in hair follicle cells and initiating autoimmunity, revealing a mechanism where stress-induced nerve activity leads to tissue damage and immune system activation.

In this study, chronic unpredictable stress affected male and female wild-derived house mice differently; stressed females gained less weight, had long grooming times, and lower immobility in tests, while stressed males showed increased hair corticosterone levels and shorter immobility times.

This study found that progesterone and its metabolite, allopregnanolone, provided anti-anxiety and anti-depressive effects in female mice, potentially independent of nuclear progestin receptors but requiring 5α-reduction and estradiol's influence on brain-derived neurotrophic factor.

This study developed finite element models to examine skin's biomechanical properties, finding that structural heterogeneities like Rete ridges and hair follicles create distinct stress and strain patterns that may influence mechanosensation and skin integrity.

In this literature review, it was reported that mental health disorders may both contribute to and be exacerbated by various types of hair loss, and an interdisciplinary treatment model is recommended for effective diagnosis and patient care.

This paper presents a culturally informed protocol designed to improve the collection of hair samples from African Americans for cortisol measurement, illustrating its application with community-based study data.

In this study, the aqueous extract of Eclipta alba and its hydrolyzed fraction showed nootropic activity and reduced stress-induced alterations in rats.

Most bald men don't protect their scalp from the sun, and doctors should encourage prevention.

This study found that curcumin administration improved cognitive and anxiety-related behaviors and neurochemical levels in HgCl₂ exposed mice pups, suggesting protective effects against heavy metal-induced neurotoxicity.

In this study, the researchers conducted tensile tests on individual curly human hair fibers sourced from a female donor and found distinct mechanical properties under various conditions, including different strain rates and temperatures, both dry and in saline immersion.

This study found that probiotics, specifically the L. plantarum MTCC 1325 strain, may have protective effects against Alzheimer's-like symptoms induced by D-Galactose in animal models, suggesting potential therapeutic use for neurodegenerative disorders.

This case report from the study describes a dog suffering from dermatophytosis caused by Microsporum canis, presenting with alopecia on the neck and ear, illustrating the zoonotic risk of these fungal infections in both animals and humans, particularly in hot and humid climates.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.

This mini-review highlights emerging themes on how tissue stiffness, a fundamental material property, influences morphogenetic processes in living organisms, an area gaining increased attention alongside the role of mechanical forces in shaping cell behavior.

Merino wool fibers change shape with moisture, while human hair shape stays the same.

This study found that biliverdin beta and delta, metabolites of heme, play a critical role in Pseudomonas aeruginosa iron acquisition and cooperative behaviors, which are crucial for the bacterium's long-term infection in cystic fibrosis patients, suggesting potential targets for new therapies.

This article discusses the roles of epidermal stem cells in maintaining skin homeostasis and highlights how deregulation in signaling pathways may lead to cancer, but it reports no new experimental results.

In this study, combined treatment with transglutaminase and keratin significantly repaired damaged hair by improving its structural properties, reducing swelling, and enhancing crosslink activities, as evidenced by microscopy and spectroscopy analyses.

This review discusses the role of metabolism in maintaining adult stem cell homeostasis with aging and highlights the potential benefits of dietary restrictions on stem cell function and longevity. It reports no new clinical results and emphasizes the need for further molecular studies.

This study investigated the dynamic mechanical properties of fluid-immersed elastic hair beds under oscillatory shear flows, revealing a nonlinear response influenced by driving frequency and amplitude, which impacts mechanosensory signaling stability in biological processes like vasodilation and ciliary remodeling.

This study observed early cardiac effects in young minipigs following high-dose doxorubicin chemotherapy, with a decrease in heart function and changes in cardiac MRI measurements compared to controls.
