This study reports that familial frontal fibrosing alopecia was diagnosed earlier in premenopausal women compared to postmenopausal women, though long-term outcomes remain uncertain without a definitive treatment.

This report describes effective treatment of demodicosis in ferrets using amitraz, marking the first known cases in this species.

In this study, variation in the KRTAP15-1 gene in goats was linked to changes in cashmere fibre diameter, with specific variants showing dominant or recessive effects.

This study found that the fungus Microsporum gypseum enzymatically degrades keratin in human hair, with the sequence of degradation reflecting the keratinization and cystine content of individual hair components in vitro.

This review explores how cell and mouse models have contributed to understanding the mechanisms of human aging, particularly focusing on Hutchinson-Gilford Progeria Syndrome, and reports no new clinical results.

In this study, researchers found that L-cysteine interacted electrostatically with anionic ions on the surface of keratin fibers in human hair, reducing the rate of disulfide bond disconnection at pH 9.0.

Glycoproteins are present in the cell membranes of various keratin fibers.

This review explores skin manifestations associated with autoimmune liver diseases and highlights known and probable links, such as vitiligo's strong association with autoimmune hepatitis.

This report describes a new case of isolated trichothiodystrophy with characteristic brittle hair and suggests a simplified classification scheme for understanding sulfur-deficient hair disorders.

This review examines mesotherapy for local fat reduction, detailing its mechanisms, safety concerns, and the need for research toward FDA-approved uses, but reports no new clinical findings.

This study found that nutritional deficiencies, particularly in amino acids and certain micronutrients, are common in individuals with hair loss across all types of alopecia.

This study found that sheep possess a polymorphic KAP8-2 gene that shares high sequence identity with the KAP8-2 gene in goats and reindeer.

This review evaluates biotin's popularity and its purported benefits for hair improvement but finds no clinical evidence supporting its efficacy.

This study found that bioactive extracts from goat placenta, particularly when delivered via dissolving microneedles, enhanced fibroblast proliferation and skin regeneration without being toxic to skin cells, suggesting a promising dermal application for improving skin health.

The authors reported that a combination of amino acid and stem cell therapy may have extended survival in a dog with hepatocutaneous syndrome to 32 months post-diagnosis.

This study identified a novel human type I hair keratin, hHa3-II, as an isoform of a previously described hHa3 keratin, with distinct sequence differences indicating separate gene encoding.

This article reviews drug-induced pigmentation and reports no new clinical findings, highlighting difficulty in confirming drug associations due to factors like delayed onset and polypharmacy.

This consensus paper reviews expert opinions on treating telogen effluvium but reports no new clinical findings.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This study identified and characterized a murine type II hair keratin, demonstrating its presence in specific cells of hair and tongue tissues.

This study found that hair samples from children with kwashiorkor or marasmic kwashiorkor had about 20% less cystine compared to one child with adequate protein nutrition, suggesting the need for further research.

This article reviews current research on animal models for hair regrowth treatments and reports no new findings; it highlights the need for studies comparing therapy efficiency and long-term safety.

This study found that high wool-producing Wan Strain Angora rabbits had higher hair follicle density and identified potential regulatory long noncoding RNAs that may influence this trait.

This review discusses recent advances in understanding the structural hierarchy of trichocyte keratins, including their heterodimeric structure and distinct conformations impacting hair growth, with no new experimental results reported.

In a study using female Wistar rats, the researchers found that a liquid allantoin-enriched pectin hydrogel significantly improved wound healing, achieving a 71.43% reduction in healing time and complete wound closure in 15 days.

This review discusses current topical treatments, natural products, and complementary therapies for androgenetic alopecia, but it reports no new clinical results.

This study found that hair shaft keratin proteins can be reliably identified from samples as small as 0.12 cm, suggesting their potential forensic utility with typical casework sample sizes.

This review discusses the prognosis and treatment options for hair shaft disorders, finding no studies but suggesting some disorders improve with specific treatments like minoxidil and retinoids, while gentle hair care remains essential.

This article explores how various nutrients and metabolic processes impact wool and hair follicle function in animals but reports no new experimental findings.

This study explored how modifying the 8-substituent of 8-bromobenzoquinolinone affects its selectivity in inhibiting both 5 alpha-reductase isozymes in the scalp.
