This paper highlights the growing scientific interest in plant extracts for cosmetics due to their potential benefits, including antioxidant, antimicrobial, and protective properties, while emphasizing the need for quality and safety assessment to mitigate possible adverse reactions.

This study reports the development of the first rodent model for androgenetic alopecia, demonstrating that overexpression of androgen receptors in mice delays hair regeneration and can be used to test new treatments.

This study found no strong evidence that the human hairless gene is significantly involved in the development of androgenetic alopecia, though a minor role cannot be completely ruled out.

This review discusses how faecal pollution contributes to antimicrobial resistance in surface water and highlights the need for standardized methods and better wastewater management but reports no new clinical results.

This study identified three novel genetic loci associated with PCOS and found similar genetic architecture across different diagnostic criteria, with evidence suggesting genetic links between PCOS and various metabolic and psychological traits.

This study observed that applying JAK-STAT pathway inhibitors to mouse and human skin led to rapid hair growth by inducing the anagen phase of hair follicles.

This article discusses the association of acne with various systemic diseases, emphasizing the role of androgen steroids, insulin resistance, and inflammation in acne pathogenesis, but it reports no new clinical results.

This study found that early-onset androgenetic alopecia in individuals of European ancestry is significantly associated with increased odds of Parkinson's disease and is influenced by specific genetic loci, including some linked to reduced fertility.

This study identified 63 genetic loci associated with male-pattern baldness, uncovering genes and pathways that may help develop treatments and suggesting its connection to other human conditions.

This genome-wide association study identified 20 genetic signals at 15 risk loci related to severe acne, revealing new insights into its genetic predisposition, particularly affecting skin structure and maintenance.

This study observed that in wild snowshoe hares, gene expression patterns during seasonal coat color change show a consistent lag between gene expression and visible coat color changes.

This study reports that compound heterozygous loss-of-function mutations in the HEPHL1 gene in a child were associated with abnormal hair and cognitive issues, linking altered ferroxidase activity to hair disorders.

This article reviews sebaceous immunobiology and highlights the complex role of sebaceous glands and sebocytes in skin barrier function and inflammation, particularly in acne pathogenesis, but reports no new results.

This study found that in rodent models, the ability of D1 dopamine receptor activation to impair sensory gating is facilitated by 5α-reductase type 1, which produces allopregnanolone.

This study discovered that in *Drosophila*, knockdown of specific storage proteins in adipocytes decreased germline stem cell maintenance, implicating a role for these proteins in adult tissue regulation.

In this study, researchers linked defects in U2HR, an inhibitory region in the HR gene, to Marie Unna hereditary hypotrichosis, suggesting a mechanism for controlling hair growth and addressing hair loss.

This study found that the mammalian hairless gene encodes a corepressor protein that interacts with thyroid hormone receptors, providing insights into hair loss syndromes in humans and mice.

In this study, researchers found that transgenic expression of the Hairless gene in keratinocytes can restore hair follicle regeneration in Hr-deficient mice by repressing Wise, a modulator of Wnt signaling.

This study identified significant genetic associations with frontal fibrosing alopecia at four genomic loci, suggesting it is a genetically predisposed immuno-inflammatory disorder influenced by the HLA-B*07: 02 allele.

This review summarizes 15 years of clinical and experimental research advancements in hidradenitis suppurativa, highlighting its recognition as a uniquely healable inflammatory skin disease but reports no new clinical results.

This genome-wide association study identified 71 genetic loci linked to male pattern baldness, with 30 novel loci, explaining 38% of the risk and suggesting shared pathways with lifespan and cancer traits.

This study highlights that the mammalian target of rapamycin complex 2 (mTORC2)-Akt signaling axis is essential for hair follicle stem cells to return to their niche and regenerate effectively by regulating metabolic pathways.

This study found that deleting the CD98hc protein in mouse skin impairs wound healing and homeostasis, resembling aging effects, due to disrupted integrin signaling pathways.

This study identified the Hairless (Hr) gene-encoded protein as a corepressor that plays a crucial role in maintaining skin and hair by regulating epithelial stem cell differentiation and gene expression via chromatin remodeling, which may impact both development and disease.

This study found that despite carrying an activating Hras mutation, hair follicle stem cells integrate into normal skin without causing tumors, unlike similar mutations in the epidermis, suggesting unique tumor-suppressing mechanisms in hair follicles.

This study reported that Indian hedgehog (Ihh) signaling plays a crucial role in regulating tumor progression and metastasis in epithelial cancers, with Ihh deficiency leading to increased malignancy and metastasis in mice.

MC4R gene variants not linked to female hair loss.

This study concluded that the GIANT brain atlas, which integrates genetic and neuroanatomical variations, provides a more accurate representation of brain structure than traditional neuroanatomical atlases, allowing for better exploration of genetic influences on the brain.

This study identified a novel missense mutation in the FGF5 gene associated with the longhair phenotype in about 3% of Maine Coon cats, suggesting it may be a breed-specific variant.

Hidradenitis Suppurativa is a chronic skin condition best treated early with surgery for better outcomes and less recurrence.
