In this study, researchers found that human fingerprint ridges are formed through a modified hair follicle developmental process and spatial patterns influenced by specific signaling pathways.

This study observed that adipose tissue infiltration and ESGC displacement in scalp biopsies were more frequently found in frontal fibrosing alopecia and may play a role in the development of scarring alopecia.

This study found that reconstructed human epidermis from infant skin is more susceptible to UV damage than that from older children, with notable changes in skin cell characteristics during the early years of life.

The researchers reported that human hair keratin films exhibit color changes and reduced protein solubility after thermal treatments, suggesting their potential use in evaluating hair thermal damage instead of actual hair samples.

This study found that heating damages Asian black male and female hair cuticles without altering their structure, with damage severity increasing at higher temperatures and longer exposure times.

This study analyzed the distribution of adhesion molecules and extracellular matrix components in human fetal skin, suggesting their roles in hair follicle development.

This study proposes that the terminal tuft structure in sensory nerve endings, involving Schwann cell processes and axon fingers, potentially plays a role in mechano-electric transduction in rats.

This study used advanced analytical techniques to reveal that proteins and lipids are distributed unevenly in hair, with distinct structural differences depending on their location within the fiber.

This study suggests that age-related changes in skin elasticity reduce its stability against wrinkling, and anti-aging strategies should focus on addressing elastic mismatches between skin layers.

This study revealed that during avian skin development, complex tissue architecture results from specific cellular flows and mechanical processes that guide feather bud protrusion and elongation, with distinct differences noted in scale development, where rigidity restricts such transformations.

This study analyzed inner root sheath-specific genes in Tan sheep during various growth stages, finding peak expression at birth. The pattern of genes KRT71, KRT72, and TCHH is consistent with wool crimp, potentially influencing wool morphology.

Hair damage shows as fragility, dullness, and discoloration, varies by ethnicity, and is worsened by cosmetic procedures and diseases.

This study observed abnormal extracellular matrix patterns in hair follicles from alopecia areata patients, particularly in the dermal papilla of large anagen follicles and in catagen follicles from lesional sites.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

In this study, electron microscopy of follicular mucinosis showed severe cytoplasmic degeneration in hair follicles, with myelin figures and onion-like lamellar structures, but no indications of mucin release through degeneration or degradation were found.

This study demonstrates that polarized second harmonic generation imaging effectively monitors wool fiber stretching, revealing significant structural changes in keratin alignment that improve textile performance.

Merino wool fibers change shape with moisture, while human hair shape stays the same.

Monitoring nutrition and health is crucial for the well-being of institutionalized mentally retarded children.

This study observed that the catagen phase in hairless mice displayed a slower shortening of the mutant epithelial column, resulting in longer total follicle length and abnormalities in the connective tissue sheath and glassy membrane.

This study found that chemical treatments like perming, dyeing, and bleaching significantly alter amino acids and lipids in human hair, which may impact hair strength and quality.

This review details pathologic changes in hair follicles, such as infundibular hyperkeratosis and inflammation, but offers no new diagnostic results.

This study found that menopausal status and hormone therapy significantly affect the histology and gene expression of the introitus, with post-menopausal women showing notable tissue remodeling associated with vaginal atrophy.

In this study, optical coherence tomography was used to produce 3D images of human hair, revealing that after chemical treatment with ammonium thioglycolate, the main hair structures were not identifiable due to damage.

This research explored the impact of anticancer drugs on the scalp and found significant differences in scalp texture and features associated with alopecia, suggesting potential for assessing scalp morphology and changes during the hair regrowth process through image analysis.

This study highlights the distinct distribution patterns of extracellular matrix components in the scalp skin of male and female androgenetic alopecia patients, with increased elastin staining intensity observed in male cases.

Hair is thinner near the scalp in acute hair shedding conditions.

This study suggests that eruptive vellus hair cysts often have atypical pathological changes and likely originate from the infrainfundibulum and sebaceous duct based on keratin expression analysis.

This study demonstrated that B-mode ultrasound and shear-wave elastography could differentiate individuals at risk of developing androgenetic alopecia from healthy individuals by assessing cranial subcutaneous tissue thickness and epidermis-dermis stiffness.

This study presents a new method for evaluating cosmetic treatments by measuring the resistance of hair to mechanical wear, revealing differences related to hair ethnicity and treatment type.
