This review discusses the role of neurosteroids and androgens throughout different life stages, noting the potential disruptions caused by 5α-reductase inhibitors like finasteride, but no new clinical results are reported.

This study found that VDR knockout mice exhibited muscle and motor impairments affecting locomotor behavior, while cognitive functions such as exploration, working memory, and anxiety appeared unaffected.

This study observed that hair cuticles experience greater water-induced plasticization than hair cortex, affecting the torsional rigidity of hair fibers, which may help predict hair setting behavior.

In this study, researchers found that hair fibers exposed to bleaching and UV irradiation displayed significantly more damage, including increased adhesion and surface heterogeneity, compared to untreated hair, highlighting a synergistic degradation pathway affecting the hair cuticle's integrity.

This review suggests that while both pharmaceuticals and behavioral therapies can reduce symptoms of trichotillomania, behavioral therapies often prove more effective, though long-term effectiveness remains uncertain.

This study observed that in privately owned, intact cats, male cats exhibited significantly higher long-term hair cortisol concentrations compared to females, while environmental and behavioral factors did not significantly impact cortisol levels, suggesting individual traits may influence stress markers more than external factors.

This review highlights how natural compounds can enhance wound healing by influencing fibroblast behavior and discusses innovative biomimetic engineering and delivery methods. This source emphasizes combining traditional and modern approaches for effective and scar-free healing, while noting challenges in clinical translation.

This study evaluated a microemulsion-based flushing fluid made with castor oil that effectively removed 84.85% of mud cake formed by drilling fluid, highlighting its Newtonian fluid behavior and high wettability inversion capability.

This study found that while all hair removal techniques increased axillary erythema and skin dryness, shaving caused less erythema but more dryness than plucking or waxing, without affecting post-inflammatory hyperpigmentation or other skin properties.

This study found that several genes, including capping protein, palladin, VEGF, and HSPC-related clones, might cooperatively influence the aggregation, proliferation, and cycle control of dermal papilla cells, potentially affecting hair follicle behavior.

This study reports that soy protein isolate/hydroxyethyl cellulose nanofibrous mats embedded with diclofenac sodium and halloysite nanotubes demonstrated sustained drug release, effective antibacterial action against E. coli and B. subtilis, and maintained biocompatibility, highlighting their potential use in wound care.

This study found that 3alpha-diol, an androgen metabolite, improved cognitive and affective performance in aged male rats, suggesting its role in countering age-related decline in hippocampally-influenced behaviors.

This study explored a keratin, sodium alginate, and carboxymethyl chitosan hydrogel modified with tannic acid and found it to have promising wound-healing qualities, including similar elasticity to human skin, antimicrobial and antioxidant properties, and effective water retention. These attributes suggest potential applications in biomedical engineering.

Different treatments are effective for hair loss conditions, but results vary by individual factors.

In this study, researchers reviewed current treatments for trichotillomania and found that psychotherapy, particularly cognitive-behavioral therapy like habit reversal training, is most effective, with some medications helping to alleviate symptoms, though further study is needed on their use.

This study highlights how the COVID-19 pandemic has exacerbated stress-related dermatological issues like acne and hair loss by affecting skin and hair cycles through stress hormones, emphasizing the need for comprehensive psychoneuroendocrine-informed approaches to diagnosis and treatment.

This review outlines current treatment strategies for trichotillomania, noting that while cognitive-behavioral therapy is effective, N-acetylcysteine and memantine are also recommended due to their safety and efficacy, though evidence for other drugs like fluoxetine and naltrexone remains limited.

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 study found that Myc activation in mouse epidermis impairs keratinocyte adhesion and motility by downregulating extracellular matrix and cytoskeleton proteins, affecting hair lineage differentiation.

In studying wild meerkats, researchers observed that matriarchs with high androgen levels during late gestation exhibited increased dominance and aggression, affecting both their behavior and their offspring's aggression.

This study found that intra-follicular Wnt signaling and dermal BMP signaling oscillate differently during hair cycling in mice, affecting hair wave propagation and phases of hair growth.

This case report describes a Russian wolfhound's aggression being linked to hypothyroidism, which was successfully managed with levothyroxine therapy.

This study found that bioengineered skin substitutes developed for 21 or 28 days effectively mimic native skin's ability to absorb UV radiation, suggesting suitability for treating severe skin defects.

This study found that cocaine disrupted the relationship between certain brain androgen levels and sexual behavior in male rats, with dose-dependent effects on testosterone metabolism.

This article discusses objective methods for assessing hair loss and notes that most types of hair loss can regrow without treatment, but effective treatments for pattern or senescent alopecia remain unavailable.

The BASP classification helps predict patient behavior and improve treatment for hair loss.

This study developed a chitosan-based nanogel for minoxidil, showing in vitro sustained drug release and higher deposition compared to conventional solutions, suggesting potential as an effective topical treatment for alopecia.

Adjusting hair dryer settings improves drying efficiency and keeps hair healthy.

In this literature review, researchers highlighted that trichotillomania involves dysregulated reward circuits, abnormal sensory processing, and potential genetic factors, advancing both therapeutic strategies and understanding of the condition, but stigma and provider training gaps persist in effective care provision.

This review proposes focusing on relationships between neuroactive steroids and psychiatric disorder symptoms, rather than relying on traditional disorder classifications, and reports no new clinical findings.
