This study found that a 0.5% cationic guar gum and 0.5% anionic surfactant formulation formed stable coacervates with improved adhesion and coverage on damaged hair, suggesting it may enhance the effectiveness of hair conditioning products compared to other ratios.

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 study found that topical cepharanthine increased IGF-I production in human dermal papilla cells, suggesting it may stimulate hair growth and be a promising treatment option for androgenetic alopecia.

This study found that a gene from hamster flank organs is indirectly regulated by androgens, despite lacking direct androgen responsive elements, indicating involvement of androgen-dependent transcription factors.

This study found that repeatedly collecting hair follicles from individuals with fragile X syndrome is feasible for measuring FMR1 and FMRP levels in both home and office settings.

This study suggests that a specific region upstream of the TGF-β1 gene may play a key role in androgenetic alopecia by regulating gene expression in a cell-specific manner.

This paper introduces Concentration Growth Factor (CGF) as a potential treatment for androgenetic alopecia, but reports no clinical findings on its effectiveness in promoting hair growth.

This study found that IL-17A-producing γδ T cells play a key role in bone fracture healing by promoting bone formation, with deficiencies leading to impaired repair in mice.

Ets2 gene is crucial for placental development in mice.

This study provides evidence that human skin contains genes and enzymes necessary for producing serotonin and melatonin.

This study found that shorter CAG-repeat lengths in the androgen receptor may be associated with the development of androgen-mediated skin disorders like androgenetic alopecia, acne, and hirsutism in both men and women.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

This study found that different stabilizing mutations in Aux/IAA proteins affect root hair development in Arabidopsis by disrupting the auxin response and suggest a model where the relative abundance of these proteins determines root hair initiation.

This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

In this study, mycorrhizal fungal inoculation was associated with increased root-hair growth and enhanced drought tolerance in trifoliate orange by modulating auxin synthesis and transport under water stress conditions.

This article discusses the structure of the human type II 5 alpha-reductase gene and reports no new experimental results.

In this study, researchers found that in late pregnancy, the neuroactive progesterone metabolite allopregnanolone inhibits HPA axis responses to immune challenges via an opioid-mediated mechanism.

This study found that expressing certain PIN proteins in Arabidopsis root hairs inhibited growth by decreasing auxin levels, while PIN5 slightly stimulated growth, demonstrating differential effects on auxin transport.

This study suggests that nerve growth factor plays a crucial role in the stress-induced termination of hair growth in mice, and its antagonism might offer a therapeutic approach to mitigate stress-related hair loss.

This study found that skin-derived precursor cells in mice can originate from both neural crest and somite lineages but show functional similarities regardless of their developmental origins.

This study found that the vitamin D receptor in lampreys, which lack bones and hair, binds 1,25-dihydroxyvitamin D3 and may function to induce enzymes for detoxifying substances.

This study found that CRISPR/Cas9-mediated disruption of the FGF5 gene in goats increased hair follicle numbers and fiber length, suggesting more cashmere production could be achieved.

This study identified a cluster of genes on chromosome 17 related to hair keratin-associated proteins, including 37 genes forming seven multigene families, localized in the hair shaft's upper cortex.

In this study, dermal papilla cell-derived exosomes accelerated hair follicle growth in mice, suggesting potential for treating hair loss by modulating key signaling pathways.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.

In this study, disruptions in phospholipase A2 activity in Arabidopsis thaliana significantly impaired the plasma membrane localization of PIN proteins, affecting auxin transport and root development.

This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This study details the isolation and characterization of the human type II 5 alpha-reductase gene, which may play a role in male pseudohermaphroditism, prostate cancer, and benign prostatic hyperplasia.

This study identifies six novel keratin genes from the chromosome 17q21.2 region, suggesting their association with hair follicles, while all 27 keratin genes in the domain have been characterized transcriptionally.
