In this study, researchers evaluated the binding of keratin-associated proteins and α-keratins to human hair fibers, finding that chemical preactivation significantly enhanced binding to natural hair, while perming altered binding characteristics and increased penetration depth.

This study found that GDNF promotes hair formation and skin wound repair by enhancing the self-renewal and differentiation of bulge stem cells in mice.

This study found that pretreatment with KP-Cryst fusion proteins effectively protected Asian and Caucasian virgin hair from thermal damage by maintaining higher water content and preventing structural changes during heat application.

This study found that supplementing pregnant cashmere goats' diets according to nutritional standards improved their fiber production, growth, fertility, and the development of kids' secondary hair follicles.

In this study on Chinese Tan sheep, researchers discovered a variant of the KRTAP19-5 gene associated with decreased curvature of fine wool fibres, highlighting potential genetic markers for improving wool quality.

This study found that environmental conditions significantly influenced rabbit coat quality, while dietary linseed oil supplementation changed the fatty acid profile but did not improve coat thickness or heat protection.

This study successfully developed 3D hair follicle organoids from neonatal mouse epidermal and dermal cells, showing structural and molecular resemblance to native anagen hair follicles.

This study identified three genes in the ovine KAP13 family on chromosome 1 and found that a specific allele of KRTAP13-2 is associated with improved wool fibre diameter uniformity in Chinese Tan sheep, suggesting its potential use as a marker for enhancing wool traits.

This study found that sphinganine may improve scalp health, hair quality, and reduce hair loss in males, potentially due to increased antimicrobial peptide levels and inhibition of 5-α-reductase.

This study explored a multidimensional approach to examine body hairs' physico-chemical properties, potentially supporting their use over scalp hairs in forensic and intoxication studies.

This review discusses factors affecting hair health, types of alopecia, and the potential of phytochemicals in managing hair loss but reports no new clinical results; it highlights the need for further studies.

This review discusses the effects of chemical hair straighteners and reports associated side effects like scalp inflammation and hair damage, noting the variability of findings and the need for further research.

This study found that goat placenta extract, when combined with PEGylated liposomes and microspicule gel, significantly promoted hair regrowth in patients experiencing hair loss due to chemotherapy by enhancing hair cell proliferation without causing skin irritation over a 12-week application period.

This study explored the complex developmental processes of human hair, emphasizing the intricate interactions required for hair follicle morphogenesis and its implications for drug incorporation and concentration interpretation, particularly in early childhood.

This study detected sarcoptic mange in five free-ranging raccoon dogs in Schleswig-Holstein, Germany, with four showing severe skin lesions and potential secondary bacterial infections, suggesting they may act as vectors in disease spread.

This study found that despite chemical differences, five different brands of reconstructive hair fibers all provided successful cosmetic results in disguising hair loss in patients.

In this study, nucleotide sequence variation in the KRTAP13-3 gene was associated with changes in heterotypic hair fibre diameter variation in Chinese Tan sheep.

This study found that combined dietary supplementation of sodium hyaluronate and eggshell membrane was associated with various improvements in skin and coat health markers in healthy Ragdoll cats.

In this study, researchers found that a scallop adhesive protein (Sbp9 Δ) forms strong adhesive coatings via disulfide-sticker strategies, which also promote hair regeneration in mouse models by activating Wnt signaling and enhancing angiogenesis, proving more effective than minoxidil for androgenetic alopecia.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

In a laboratory study, researchers found that a novel Bioactive Crosslink Repair Complex improved both the protection and repair of chemically damaged hair, enhancing tensile strength, shine, and cuticle alignment when added to bleaching mixtures and leave-in conditioners.

This study found that peroxide-rich plasma-activated water caused minimal morphological damage to hair, while nitrate-rich plasma-activated water induced significant damage, especially in porous hair types.

This study reported a new method enabling the observation of the full leg regeneration process in the crustacean *Parhyale hawaiensis* over 10 days, capturing cellular resolution while minimizing photodamage, through innovative imaging techniques and computer-assisted cell tracking.

This study found that scalp cooling resulted in visible hair retention in 53% of breast cancer patients undergoing Epirubicin/Cyclophosphamide and Paclitaxel treatment, with factors like hair bulb diameter, shaft diameter, and anagen rate significantly predicting outcomes.

This review highlights the critical role of mitochondrial dysfunction in hair loss, particularly androgenetic alopecia, and explores potential therapies targeting mitochondrial pathways to improve hair health, underscoring the need for further research in this area.

This study used atomic force microscopy to identify significant morphological differences in hair from patients with lichen planopilaris compared to healthy controls, noting more scratches, uneven edges, and pitted scales in affected hair, which may aid future research on the condition.

This study analyzed the genetic variations of the KAP20-1 gene in Chinese Tan sheep lambs and found that the G variant was linked to an increased mean fibre curvature in their fine wool fibres, potentially influencing breeding strategies for this wool trait.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.
