In this study, heritability analyses in twins and siblings revealed that genetic factors predominantly influence hair diameter and curvature, with notable sex differences in their genetic impact.

This case report describes a canine with alopecia areata universalis treated with oral ciclosporin, which was associated with hair regrowth, but some areas remained hairless after 17 months.

This study confirms that scalp hair follicles in Chilean subjects exhibit seasonal variations, with a higher percentage of follicles in the telogen (resting) phase during the summer compared to the winter.

In this study, researchers observed that the combination of hair progenitors and their micro-niche changes every three days in mouse zigzag hair, and disruptions in specific genes affected this rhythm, highlighting the importance of this periodic change for normal hair morphology.

This study identified 417 genes with differential expression at varying stages of cashmere growth in goats, highlighting their potential role in tissue remodeling and cashmere regeneration.

In this study, researchers examined chronic hepatitis B patients and found that those undergoing interferon therapy reported higher quality of life than those on non-antiviral or nucleoside/nucleotide analogue treatments, despite potential side effects.

This systematic review found that chitosan-based wound therapy may accelerate wound healing by reducing inflammation and modulating immune response, but notes limited clinical trials to date.

This study found that examining hair morphology provides deeper insights than classification, suggesting a potential population stratification artefact between hair curvature and cross-sectional shapes in the examined admixed African-European sample.

This study found that in Alcorcón, Spain, migrants from Sub-Saharan Africa, the Caribbean, and Latin-America had a higher risk of COVID-19 infection during the first wave compared to Spaniards.

This study found that follicular unit extraction megasession resulted in high patient satisfaction without infections for treating severe androgenetic alopecia, offering a promising one-stage option compared to multi-stage hair transplants.

This study suggests that β-catenin plays an important role in wool follicle development in transgenic sheep by enhancing the expression of keratin protein genes.

This study reports an association between the ESR2 gene variant rs10137185 and female-pattern hair loss in German patients.

This study found that hairline measurements in white Spanish women differ from those previously reported for American women, which may be important for hair transplantation evaluations in alopecia cases.

This study revealed key cellular dynamics and interactions during early embryonic mouse skin development, highlighting complex transitions from precursor states to diverse multilayered structures.

This study identified key genes and signaling pathways involved in cashmere goat hair follicle growth cycles, influenced by melatonin implantation, suggesting a basis for further research on melatonin's regulatory mechanism.

In this study, researchers identified loss of function variants in the HR gene as likely causes of the distinct roaning hair coat seen in lykoi cats.

This review discusses the role of dermal papilla cells in hair follicle morphogenesis and regeneration and reports no new results; the authors emphasize the importance of these cells in hair growth and pigmentation regulation.

This review discusses the formation and structure of the cornified cell envelope in the epidermis, highlighting biochemical pathways and genetic factors, but presents no new experimental results.

This review discusses the scalp and follicular microbiome's potential role in hair diseases and the emerging interest in microbiome-targeted therapies, but reports no new clinical findings.

This study suggests that continuing finasteride therapy after mastectomy does not significantly affect gynecomastia recurrence in men taking finasteride for alopecia.

In this study, the authors identified the DHRS9 SNP rs72623193 as most significantly associated with response to dutasteride in treating male pattern hair loss, with additional variants potentially contributing.

This study applied a prediction model based on five SNPs to Russian males with male pattern hair loss, finding a significant association between the AR genomic region and high dihydrotestosterone levels in these patients.

This review discusses the evaluation of animal models for hair research and regeneration, highlighting their importance and limitations, and calls for improved approaches to advance understanding of human hair diseases.

This review discusses the molecular mechanisms of androgen action in human hair follicles and reports no new findings; the authors emphasize the need for further research to improve treatments for hair disorders.

This study observed that men with frontal and moderate vertex baldness between ages 40 and 50 had a higher risk of aggressive prostate cancer, suggesting a potential link between baldness pattern and cancer risk.

This study reports the first documentation of mural, mucinotic, isthmus folliculitis alopecia in Norwegian puffin dogs, noting that ciclosporin treatment led to remission while other treatments were less effective.

This study found that topical application of partial proteasomal inhibitors accelerates hair growth by stabilizing β-catenin and disrupting the hair cycle's normal balance of activation and quiescence.

In this study, overexpression of miR-29 in mice led to aging-related phenotypes and early lethality, demonstrating its significant role in driving aging processes.

This study used single-cell ATAC sequencing to map chromatin accessibility in developing mouse hair follicles, offering insights into the transcriptional regulation and epigenetic mechanisms underlying hair follicle development.

This study found that cashmere has a significantly smaller mean fiber diameter compared to sheep and goat wool, and identified key proteins that may influence this difference.
