In this study, the researchers measured and discussed the friction and wear properties of various hair types against synthetic skin and other hair, finding variations based on factors like ethnicity, hair condition, and environmental conditions.

In this study, researchers found that the curliness of human hair is associated with an asymmetric structure at the cellular level, particularly in the differentiation of the precortex.

This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.

This study concluded that the Scalp Photographic Index is a reliable and validated tool for objectively classifying and scoring various scalp conditions.

This study provides the first direct evidence that spermidine can stimulate hair growth and modulate human epithelial stem cell biology in cultured human hair follicles.

Mice with extra sheep genes had hair that fell out and regrew in cycles.

This study found that Polyquaternium-87 significantly reduced friction forces on hair surfaces treated with various shampoo formulations, highlighting its potential for improving hair care products.

This report suggests that peripilar hair casts, potentially linked to modern hair styling or mild trichotillomania, may be more prevalent than currently reported.

This study compared two PRP preparation techniques for treating androgenetic alopecia and found that both methods led to some improvement in hair loss, but further research is suggested due to variations in PRP preparation.

This study demonstrated that human hair shafts can be anatomically separated to obtain intact micron and nano keratin filaments using solvents like performic acid and urea.

This study concluded that the curliness of human hair, regardless of ethnicity, originates from the inhomogeneous internal nanostructure due to differences in the distribution of two types of cortices.

This research highlights the potential of using bioactive silk-based nanofiber dressings to improve the healing of diabetic wounds, suggesting that further studies are needed to refine these formulations and confirm their effectiveness in larger clinical trials.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This study found that hair curvature in merino wool is influenced by differences in cell type length rather than the proportions of orthocortical and paracortical cells.

This study found that the weak tensile strength of pili torti hair may result from loose keratin intermediate filaments due to abnormalities in disulfide bonds.

This study found that the X-ray patterns of stretched mammalian hair (β-keratin) are similar to those of natural silk (fibrion), suggesting a similar elastic mechanism involving reversible intra-molecular transformations.

This study found that the cuticle layer of hair contributes approximately 60% to bending stress, highlighting its significant role in the mechanical properties of hair stiffness.

This study introduces a modular fiber model to investigate how changes in microstructural properties of wool affect its critical buckling load, highlighting potential uses and areas needing further research in wool fiber biophysics.

This abstract presents a clinical case of a woman with traction alopecia and discusses trichoscopic findings without reporting any new research results.

This study suggests that varying intersheet interactions may explain the differences between the two polymorphic forms of macrofibril assembly in Merino wool and hair.

This study found that while yak belly hair is chemically similar to human hair, its higher porosity and lower mechanical strength limit its usefulness as a substitute in hair dye development.

This integrative review developed a Spiral Model to better represent human hair follicle dynamics and aging, which may assist in distinguishing natural aging from pathological changes and improving trichological interventions.

This study demonstrated that human hair can be coated with Fe3O4 nanoparticles, allowing it to be oriented and moved by a magnetic field, which may enhance drug delivery and hair care applications.

This study reports pseudopili annulati in a dark-haired Chinese girl, identifying the unique appearance and structural characteristics of her hair without finding abnormalities in the cuticle and cortex.

This study found that keratin-based particles were able to recover and enhance the mechanical properties and thermal stability of virgin and overbleached Asian hair, improving its strength and smoothness by around 40%, and demonstrated safety in human skin keratinocytes.

This study using an apertureless scanning near-field optical microscope found that dye restricted to hair's periphery remains mainly on the surface and in the endocuticle.

This study presents an improved reference genome for the African spiny mouse, which may aid in understanding its tissue regeneration at the molecular level.

This study found that a wound dressing made from egg white proteins, polyvinyl alcohol, and 1 mg/ml graphene oxide was most effective in promoting skin wound healing and tissue regeneration.

This study developed multifunctional nanofiber wound dressings that significantly reduced bacteria and promoted healing in a mouse wound model by incorporating antibacterial and growth-promoting agents.
