This case report describes a newly identified condition called loose anagen hair of childhood, characterized by easily pluckable hair in two young boys, with variable duration and no scalp inflammation or scarring.

This study investigated hair fibre growth in Angora and Cashmere goats, finding differences in growth rates and seasonal dependencies, and examined the effects of prolactin and melatonin on protein deposition in hair follicles.

This study reported that novel kainate derivatives, especially ZCZ90, maintained potency in affecting proprioceptive sensory organ firing, aiding future receptor studies for potential treatment innovations.

This study observed that during male silkmoth development, trichogen cells in olfactory sensilla undergo significant membrane recycling, contributing to sensillum structure formation in a precisely timed series of stages.

This article proposes a classification system for hair casts to resolve confusion in existing literature and describes a staining technique to distinguish peripilar keratin casts from other hair disorders, without providing new clinical results.

This study observed that in frizzled 6 null mice, initially uncorrelated hair follicle orientations develop into highly ordered patterns over time, suggesting possible mechanisms for biological structure patterning.

This study found that bovine slick mutations may enhance heat stress responses in mice but do not lead to the expected hair phenotype changes.

In this study, researchers developed a new 6-point scale for evaluating heat damage to hair from straighteners, finding a strong correlation between technical damage measurements and human perception of hair damage.

In this study, researchers developed a novel composite fiber by incorporating minoxidil sulfate-loaded ZIF-8 nanoparticles into a polyvinyl alcohol matrix, achieving sustained drug release for up to 220 hours, strong mechanical properties, and the capability for cosmetic applications like wigs.

This study found that while SP did not enhance linear hair growth in cultured hair follicles, it prolonged the anagen phase and altered the expression of growth factors and apoptosis-related molecules, suggesting a stimulatory effect on hair growth.

This study reported that using 2D solid-state NMR techniques on extensively labeled mouse fur improves resolution in detecting chemical shifts and secondary structure features, potentially aiding the analysis of the effects of commercial or therapeutic treatments on specific amino acids.

This study found that transgenic mice overexpressing the SSAT gene under a metallothionein promoter suffered delayed hair loss and were highly sensitive to polyamine analogues, which led to significant liver changes and mortality.

This study challenges the idea that tarantulas produce silk from their feet to steady themselves during falls, suggesting instead that the hairs on their feet are chemosensors secreting lymph, not silk.

This study found that applying hair conditioner during a permanent wave process in the middle rather than early or late improves tensile strength, hydration, and maintains healthier hair cuticle structure.

This study found that silk fibroin/sodium alginate scaffolds seeded with dermal papilla cells may accelerate skin repair and hair follicle regeneration in a rat model.

This study found that distinct hair fiber structures among blue fox, mink, and otter rabbit can be used to identify and differentiate these fur types.

This study found that controlled thermal straightening can achieve irreversible smoothing of curly hair without chemicals, with effectiveness dependent on temperature and cycles, and silicone enhancing straightening quality.

This review discusses past research on the chemical and physical properties of human hair, focusing on structural analysis and mechanical property measurements with methods like SEM and tension tests, but adds no new findings.

This case report describes two siblings with Keratosis Follicularis Spinulosa Decalvans, illustrating its manifestations in a 9-year-old boy and a 5-year-old girl.

This study found that anisotropic osmolyte solutions may improve hair follicle turnover and condition in both in vitro and in silico models, as well as in human volunteers with hair disorders.

This study developed a precise and sensitive HPLC-MS/MS method for analyzing the pharmacokinetics of perospirone hydrochloride in human plasma, establishing it as suitable for clinical studies.

This study suggests that ultra-fine powders of steamed and lyophilized mature silkworms may have enhanced pharmacological effects compared to fine powders, possibly due to their smaller particle size.

In this study, 467 genes with differential expression between fine-wool and coarse-wool sheep, particularly those related to lipid metabolism, were identified as potentially influencing wool fibre diameter.

This study found that genetic variation in the KRTAP21-2 gene among crossbred Merino lambs was associated with differences in wool traits, particularly mean staple length.

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.

In this study, researchers observed that spiral ganglion neurites created more branched networks near FGF-1-coupled beads compared to control beads, highlighting FGF-1's role in hair cell innervation development.

This study found that medium-sized particles (643 and 646 nm) penetrated deeper into porcine hair follicles in vitro than smaller or larger particles, suggesting size-selective targeting within follicular sites.

Pili annulati is caused by a protein metabolism disorder affecting hair structure.

This study found that a mathematical model predicts signaling heterogeneity in epithelial outer root sheath cells is necessary for hair follicles to maintain size and grow long hair fibers, supported by molecular experiments.
