This study provides evidence supporting a regulatory relationship between the transcriptional regulator Hoxc13 and Krtap16 genes, which are crucial for proper hair growth in mice.

This review explores the structure and development of the hair cuticle, highlighting difficulties in studying some aspects and proposing new experimental approaches, but reports no new clinical results.

This consensus report outlines Brazilian dermatologists' recommendations for treating alopecia areata, highlighting intralesional corticosteroids for localized cases and systemic therapy for extensive, active disease, along with monitoring side effects.

This study highlights rapid advances in alopecia areata treatment following the identification of genetic variants associated with increased disease risk, suggesting potential for precision medicine approaches.

This study mapped a spontaneous mouse hair mutation, "hague," to keratin genes on chromosome 15 but found no gene mutations in hague mice.

This study indicates potential differences in the hair spectra of individuals with mood disorders, suggesting a promising, yet preliminary, method for noninvasive prediagnosis.

This study observed that fetal hair follicle melanocytes varied in morphology and development stages, with melanosomes undergoing degradation into irregular pigment particles within keratinocytes.

This research detailed a single-cell atlas showing dynamic hair follicle stem cell states associated with the hair cycle during aging in mice, highlighting differences in chromatin landscape linked to stem cell differentiation and quiescence, and providing a foundation for future exploration of aging reversal.

In this study, NuMA's microtubule-binding domain was found to be crucial for correct spindle orientation and skin differentiation, with its loss leading to neonatal lethality in mice.

In this study, patients with alopecia areata showed altered hypothalamic activity and connectivity, which may be linked to the neurophysiological basis of psychological stress experienced by these patients, as assessed by functional MRI and correlated with neuropsychological evaluations.

This study found that Magra sheep with high-luster wool exhibited significantly higher expression of keratin genes, suggesting that increased keratin protein levels may be crucial for wool luster.

This study identified novel genetic variants in APOE ε4 non-carriers associated with Alzheimer's disease age-of-onset, linking them to regulatory mechanisms like the unfolded protein response in the pathology of Alzheimer's and other degenerative diseases.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

This case report describes a patient with alopecia areata treated with diphencyprone, who experienced both successful hair regrowth and later intense hair shedding, compatible with telogen effluvium, suggesting a possible link between contact dermatitis treatments and telogen effluvium onset.

This study found that a single session of botulinum toxin, whether administered subcutaneously or combined intramuscularly and subcutaneously, did not significantly improve hair density or hair quality in men with androgenetic alopecia after six months.

This study reports the cloning and expression details of two new human type II keratins, K6irs3 and K6irs4, in the hair follicle's inner root sheath, suggesting a distinct functional role related to hair structure.

This study characterized a new human keratin, hK6irs1, specifically found in the inner root sheath of hair follicles, which suggests its role in the structural integrity and guidance of growing hair shafts.

This study reports that the differential expression patterns of three retinaldehyde dehydrogenases suggest a regulated need for retinoic acid synthesis in various organs during late mouse organogenesis.

This study found that the hairless gene product (Hr) suppresses VDR-mediated gene activation by directly interacting with the vitamin D receptor, potentially affecting hair follicle function.

This study identifies NFAT5 as a crucial transcription factor necessary for triggering innate immune responses in the blood vessel lining that lead to atherosclerosis under hypertonic stress conditions.

This preliminary study suggests that Raman micro-spectroscopy can help differentiate basal cell carcinoma from hair follicles in skin tissue sections, although some misclassification of hair follicles as carcinoma was observed.

This study identified two novel genes, pmg-1 and pmg-2, expressed in various skin and gland tissues and potentially involved in the differentiation of epithelial cells in epidermal appendages.

This study found that the ocular surface epithelium in mice contains distinct stem cell populations with unique cell division dynamics that change behaviorally in response to different levels of injury.

Allopregnanolone likely doesn't influence ethanol's rewarding effects in these mice.

This review discusses the complex interplay of genetic and environmental factors in Type 1 Diabetes Mellitus and its frequent association with other autoimmune conditions, focusing on personalized medicine to potentially improve patient care.

Using a transgenic pig model, this study demonstrated that LGR5 is a marker of hair follicle stem cells across different species, with important similarities and differences in gene expression and developmental processes.

This review highlights that extracts from *Hamamelis virginiana* (witch hazel) exhibit antimicrobial, anti-inflammatory, antioxidant, and wound-healing properties in various studies, showing promise for future therapeutic use in dermatology and cosmetology, particularly for skin treatments.

This research review highlights the potential of exosome therapy to transform stroke treatment, reporting that in animal models, exosomes can reduce neuroinflammation, oxidative stress, and cell death, while promoting brain repair and regeneration. However, more evidence is needed before clinical applications in humans are established.

This study found that modern styling cosmetics can significantly alter hair structure through changes in interfacial chemistry and cohesion, particularly when applied to already damaged hair.

Plant-based treatments may help reduce BPH symptoms, but more research is needed.
