This study suggests that collecting hair samples from all scalp regions may be a viable alternative for measuring cortisol in individuals with Afro-textured or extremely short hair, aligning results with traditional methods.

This study identified the FGF5:c.578C>T variant as linked to long hair in Akitas in Japan and suggests that genetic testing could help improve their breeding practices and welfare.

This study analyzed the transcriptome of the Tianzhu white yak, identifying differential transcripts that shed light on the molecular mechanisms influencing hair length growth variation in this species.

This study observed significant differences in hair and cashmere properties among three goat breeds in Southwest China, noting better quality cashmere in Inner Mongolia cashmere goats and their crossbreed compared to Dazu black goats.

The researchers reported that certain physical characteristics of hair shafts, such as length and color, may influence mtDNA read counts and degradation state when analyzed by massively parallel sequencing.

The researchers reported creating a Human Hair Atlas that maps over 1200 molecular species in hair, revealing up to 50% variation in metabolite and lipid levels along the hair's length, and identified 122 exposome-related compounds from personal care products.

This study found no significant differences in hair growth between two formulas of hair tonic from meniran extract, one with a menthol enhancer, despite variations in hair length and weight measurements.

This study developed and validated the Hair-Shedding Visual Scale for Asian Women, finding it to be an effective tool for identifying FPHL and TE.

This study identified genetic loci and pathways associated with long hair growth in the Tianzhu white yak, providing new insights into the genetic mechanisms of this trait.

This study found that a 5% concentration of terentang stem bark extract was the most effective in promoting hair growth in male rabbits.

This study identified several genetic variants associated with cattle hair coat length, which may help breed more heat-tolerant animals by facilitating efficient heat loss.

This study found that variation in the ovine KRTAP27-1 gene may influence wool growth, with certain genotypes associated with higher mean staple length and greasy fleece weight in sheep.

This review discusses the biology of hair follicles across various species and their role in fiber quality, but reports no new experimental findings.

This study confirms the presence of large structural variations in the genome of Nellore cattle, which may contribute to their environmental adaptation to tropical regions.

This article reviews common hair growth abnormalities in children, emphasizing the importance of distinguishing normal development from potential signs of metabolic disorders and indicates no new clinical results.

This study found that in Chinese Alashan Left Banner White Cashmere goats, guard hair length was positively correlated with guard hair diameter and down fiber length, but not with body weight at first combing.

This study found that a specific genetic mutation in the Fgf5 gene may contribute to the long-hair trait in Angora rabbits by reducing the binding capacity of the FGF5 protein.

In this study, researchers observed significant variations in the hierarchical structures of domestic cat hairs and whiskers, showing that local mechanical properties are influenced by the distribution and composition of internal granules and calcium enrichment along the hair's length.

This article reviews techniques for achieving natural-appearing hair restoration results in women and reports no new research findings.

This study in western Hudson Bay, Canada, examined trace elements in the hair of adult male polar bears and found significant differences in concentration patterns along the hair length, suggesting laser ablation ICP-MS is a promising tool for monitoring these variations over time.

This study found that expression and variants of the KRT84 gene are associated with important wool traits in Gansu Alpine Fine-wool sheep, suggesting its potential use as a genetic marker for wool trait selection.

This study developed a geometric framework for estimating safe donor harvesting in hair transplants, showing that individual hair characteristics like caliber and length significantly affect donor capacity.

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 mutations in the FGF5 gene are the primary genetic factor causing long hair in domestic cats through an autosomal recessive mechanism.

This study found that rice genotypes exhibit significant variation in root hair properties under low phosphorus conditions, with genotype DJ123 showing particularly efficient root hair growth and phosphorus uptake.

This research found that spontaneous and depilation-induced hair growth result in biologically distinct telogen phases in murine skin, with variations in thickness, pigment content, and hair follicle composition.

The researchers found that using hair analysis to detect past use of cannabinoids or amphetamines in individuals with psychosis was limited by individual variations in hair growth rates, affecting the method's reliability.

This study found that root hair length and density in rice are controlled by distinct genomic regions, with 18 regions identified but no overlap between the traits.

In this study, researchers found that the morphology, composition, and elemental enrichment of domestic cat hairs vary significantly along their length, contributing to a functional gradient that affects mechanical properties and challenging assumptions of uniformity in hair structure.

This study found that bimatoprost was significantly more effective than sweet almond oil in increasing eyebrow hair density and length in young women over a 5-week period.
