In this study, researchers developed a regression model that reasonably predicts consumer-perceived hair breakage using various parameters such as hair smoothness, detangling forces, extensional strength, and hair density among Indian women.

This study developed an in vitro 3D organoid model using dermal papilla spheroids and found that it enhances growth factor expression and extracellular matrix production, which could aid drug screening for hair regeneration.

This study found that stabilizing HIF1A in balding hair follicle cells shifted their metabolism towards glycolysis, reducing oxidative stress and potentially promoting hair growth.

This speculative review discusses hair cycle-dependent fibroblast dynamics and possible impacts on human hair growth, synthesizing current literature without presenting new clinical findings.

This theoretical research project proposes the Carnivore Follicular Integrity Framework, suggesting that animal-based diets may support hair follicle stability through various evolutionary and mechanistic pathways.

In this study, Dodatek A operationalizes the Functional Androgen Axis framework by defining three system-level indices and an efficiency metric to describe androgen function, incorporating key methodological improvements and acknowledging significant limitations for future empirical validation.

This paper reviews the role of pharmacokinetic/pharmacodynamic modeling in drug development, emphasizing its application for drug dosing guidance, safety resolution, and therapeutic monitoring improvement, without presenting new clinical results.

In this study, researchers used quantitative fate mapping to investigate how the infundibulum, part of the epidermis, is maintained during adulthood, finding that progenitors maintain this tissue through stochastic cell fate choices, with cells at the bottom providing transient support during hair growth phases.

Farudodstat may help treat alopecia areata by protecting hair follicles.

This study found that the Lim-homeodomain transcription factor Lhx2 regulates Sonic Hedgehog signaling during early retinal neurogenesis in mice by controlling the expression of pathway genes in retinal progenitor cells.

This study explores the mechanisms of root hair growth in simulated microgravity by examining the cytoskeleton topography and calcium ion distribution, but reports no new results.

In this study, trypsin digestion was found to be a faster and more efficient method than the explant technique for extracting bulge-derived keratinocytes from adult scalp biopsies.

This study suggests that the prevalence of red beards in individuals with dark hair may be explained by Thayer’s Theorem of countershading.

This study found that hairless mice with homozygous mutations developed significantly more aggressive basal cell carcinomas and a heightened inflammatory response to UVB exposure compared to their haired littermates.

This study found that asynchronous differentiation in human anagen hair follicles involves specific localization of c-Myc and interrelated genes Max and Bin1 along the inner root sheath.

This study developed a validated murine model of hypertrophic scar contraction, demonstrating similarities to human skin and observing graft contraction and tissue characteristics over time.

This study found that altering mechanical signals in mouse wounds, particularly through FAK inhibition, increased hair regeneration by modulating wound stiffness and gene expression linked to tissue regeneration.

This study found that IL-1α and IL-7 secreted from keratinocytes in a genetically engineered mouse model can stimulate the expansion of γδT-cells, aiding in the proliferation of epidermal stem cells for wound healing.

This study reports that a specific transporter protein in Staphylococcus hominis is responsible for transporting a malodour precursor, thereby playing a key role in human body odor production.

Oxidized trichocyte keratin has a helical dislocation in its structure.

This study found that in chimaeric mice models, the pigment distribution and pattern were influenced by the sash genotype, demonstrating the melanocyte-autonomous nature of the beige and leaden loci.

This study found that Rac1 activity in specific skin compartments is sufficient for hair formation, but results in hair with altered structure and pigmentation compared to normal.

This study observed that while calcium influx does not initiate root hairs in Arabidopsis thaliana, it may be crucial for sustaining their elongation through elevated calcium levels at the root hair tip.

This study found that polyamine levels in hair samples differ between androgenic alopecia and alopecia areata, suggesting potential non-invasive biomarkers to distinguish between these hair loss conditions.

This study found that targeting HSP70 can suppress basal cell carcinoma growth, underscoring the importance of tumor microenvironment interactions in cancer progression.

This study reported that an HS-associated NCSTN mutation in iPSC-derived skin organoids led to altered hair follicle stem cell differentiation and increased expression of proteins linked to HS inflammation.

Sulphur in hair follicles increases from the bulb and then levels off, while other elements vary in distribution.

This study introduces a spherical skin model that effectively mimics key features of human skin, offering a scalable and rapid alternative for non-animal dermatological and cosmetic testing.

This review highlights the limitations of mouse models in human hair loss research and emphasizes the potential of using human cell bioengineered models and artificial intelligence for future advancements, but reports no new clinical results.

This study reports that nonscarring diffuse hair loss in women is most common in the 21-40 age group, with low serum ferritin, vitamin B12, and vitamin D3 levels contributing to its pathogenesis.
