This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.

This report expands the known genetic mutations linked to monilethrix by identifying new patients with KRT83 mutations, confirming its role as a causative gene for this hair disorder.

This study observed that lipids in human hair accumulate in specific areas and do not significantly impact water permeability, highlighting the utility of AFMIR for studying complex biomaterials.

This study found that keratin-associated proteins form part of the developing exocuticle and a-layer in hair fiber cuticle cells, while cornified envelope proteins were absent.

This study investigated the effects of wool-derived hydrolysed keratin peptides on relaxed textured hair and found that mid- and high-molecular weight peptides improved mechanical strength and reduced breakage in different humidity conditions.

This study reviews various skin models and methodologies used to assess the follicular penetration of nanoparticle-based drugs, highlighting inconsistencies that complicate comparisons and aims to establish more uniform protocols for clearer study outcomes.

This study found that Sox9 plays a critical role in maintaining radial glial progenitor cells and regulates the timing of their generation of upper-layer cortical neurons.

This study examined the age-related changes in the dermal structure of goat skin, providing baseline data on its histomorphology, histochemistry, and histoenzymology.

This study found that Keratin 26 is expressed differently in hair follicle phases, particularly during catagen and telogen, influencing cashmere growth and interacting antagonistically with the BMP signaling pathway.

This research found that Dlx3 plays a central role in hair formation and regeneration, with its absence leading to alopecia through disrupted differentiation and signaling pathways.

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 review discusses Wnt signaling pathways in skin development and stem cell regulation, highlighting potential interactions with other pathways but reports no new findings.

This study describes the expression patterns of type I inner root sheath keratin proteins K25–K28 in human hair follicles, highlighting their distinct distribution within different layers.

This review observed limited evidence of clinically significant benefits from treatments for acute central serous chorioretinopathy, which often resolves spontaneously, but identified PDT and micropulse laser as the most promising for further trials.

This review discusses various types of hair dyes, their mechanisms of action, molecular structures, application methods, and formulation aspects, but reports no new research findings.

This study found that a keratin mutation may cause diffuse partial woolly hair associated with loose anagen hair syndrome in some families, but other genetic factors could play a role in different cases.

In this study, researchers found that Notch signaling is crucial for late-stage epidermal differentiation and postnatal hair cycle homeostasis by regulating hair follicle stem cell proliferation and differentiation.

This study found that transcription factors HOXC13, LEF1, and FOXN1 repress DSG4 transcription, with the Notch pathway possibly involved in maintaining DSG4 expression in hair follicles.

This study suggests that TGase 3 may contribute to hair fiber scaffolding by forming specific isopeptide bonds between keratin intermediate filaments and keratin-associated proteins.

This study found that mu-crystallin gene expression in mouse skin is highest during the anagen phase of hair development, suggesting its possible role in hair follicle growth.

This study found that large excisional wounds in rats across seven strains do not regenerate new hair follicles, unlike in mice, possibly due to differences in epidermal competence and transcriptional profiles.

This study describes the presence of holes in hair fibers, absent in hair follicles, likely forming from daily care actions and removal of extractable substances.

In this review, the authors highlight the importance of hair care for men, suggesting that proper routines and a nutrient-rich diet can help maintain scalp health, prevent hair loss, and promote a sense of well-being.

This study found that human hair exhibits significant deformation in its intermediate filaments under strain, with recovery taking about 1000 minutes, suggesting a self-healing period post-mechanical stress. Additionally, cuticle scales deform much less than the cortex, and the Poisson ratio aligns with soft matter properties.

This study utilized a novel mass spectrometry imaging technique to demonstrate that argan, avocado, and coconut oils are incorporated into hair fibers during cosmetic treatments, supporting their potential use in formulations for enhancing hair health and treating conditions like alopecia.

This review synthesizes evidence on platelet-derived bioproducts like PRP and PRF, highlighting their role in tissue regeneration and their benefits in aesthetic medicine applications such as hair restoration, scar treatment, and wound healing.

This study cataloged human type II hair keratins, detailing their expression and differentiation roles in hair follicles and comparing them with type I keratins to explore keratin-pairing principles.

This study reports that human hair follicle stem cells express different surface markers than mouse stem cells, facilitating their isolation and potentially aiding in the development of cell-based skin treatments.

K39 and K40 are the last keratins expressed in hair development, completing the hair keratin catalog.

This study found that KRTAP2 proteins predominantly express in the hair shaft cortex of humans, interact with hair keratins, and play crucial roles in hair shaft keratinization.
