In this study, researchers found that the primary cause of slippage and detachment of keratin capsules in hair extensions is the re-contamination by oily residues from the hairdresser's hands, rather than the use of hair care products like masks or conditioners.

This study operationalizes a four-step workflow for selecting donor hair for capsule extensions, translating surgical trichology insights into an extension-specific protocol to enhance natural hair optics and biomechanics, suitable for premium extension services.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

In this study, the authors found that rabbit hair material ground for 8 hours had better suitability and histocompatibility for injectable soft tissue augmentation compared to other tested formulations.

This study describes a method for serially cultivating adult human hair follicle keratinocytes using a specific growth substrate and cryogenic storage, enabling subculture and immunofluorescence studies.

This study evaluated a polyherbal hair oil formulation that included hibiscus flower and other plant extracts, suggesting it may increase hair growth, reduce hair loss, and provide dandruff protection.

This study investigated the interdigital glands in sheep, highlighting their apocrine sweat glands' ultrastructural characteristics and positive lectin reaction, but reported no new clinical results.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

In this study, researchers found that a polyphenolic extract from Annurca apples, high in procyanidin B2, increased hair growth, density, and keratin content in healthy subjects after 2 months of use, and stimulated keratin biosynthesis in vitro.

This study demonstrated that a daily oral supplement of 1000 mg Kera-Diet® improved hair and nail conditions in women experiencing acute telogen effluvium and brittle nail syndrome over three months.

In this study, a keratin hydrogel improved survival rates and functional recovery in rats with spinal cord injuries, suggesting potential for SCI treatment that merits further investigation.

This research found that keratin hydrogels derived from human hair may support cell viability and proliferation, indicating potential as 2D and 3D soft tissue culture scaffolds.

In this study, researchers found that supplementation with L-cystine, either alone or with a keratin hydrolysate, significantly improved hair density, hair and nail brightness, and nail growth in women experiencing acute telogen effluvium and brittle nail syndrome over three months.

This study identified and characterized progenitor cells from equine feet that may play a role in the pathogenesis and recovery of laminitis, suggesting potential therapeutic targets for treatment.

This study found that Cynatine HNS significantly improved hair and nail health in women after 90 days compared to placebo.

This study found that hair with lower levels of keratin associated proteins reduced the foreign body response in mouse subcutaneous implant tests compared to hair with higher keratin levels.

This study demonstrated that keratin K124 is specific to equine hoof lamellar tissue and established monoclonal antibodies that can specifically recognize K124 without cross-reacting with other tissues.

This study observed that keratose, derived from human hair, integrated well in mouse tissue and remodeled with collagen, suggesting potential as a non-toxic biomaterial for regenerative applications.

This study found that a peptide treatment using Protein disulphide isomerase improved the mechanical and thermal properties of over-bleached hair by promoting deeper peptide penetration and attachment.

This research examined the ultrastructure of deer hair fibers and found significant variations in diameter, cuticle thickness, and intermediate filament arrangements among different fiber types.

This study found that keratin-associated proteins form part of the developing exocuticle and a-layer in hair fiber cuticle cells, while cornified envelope proteins were absent.

This study found that taking oral FKH supplements for 90 days improved facial skin, hair, and nail appearance, and highlighted the role of free L-amino acids as potentially beneficial beyond their protein-building functions.

This study found that tetracycline can adhere to hair follicle structures and disrupt cell metabolism, potentially damaging healthy human cells as well as pathogens.

In this study, a liposomal-encapsulated Sesbania grandiflora formulation significantly improved hair and scalp health in adults with hair loss over 180 days, showing enhanced hair density, thickness, growth rate, and tensile strength compared to placebo, with no related adverse events reported.

In this study, researchers found that a standardized extract of Sesbania grandiflora (SesZen-Bio™) improved hair density and thickness, as well as increased serum ferritin levels, over an 8-week period among participants, suggesting enhanced keratin production and follicle growth.

This study demonstrated that intact adult human dermal papillae can induce hair growth when implanted into mouse hair follicles, highlighting their potential for advancing hair follicle biology and therapeutic approaches.

This review discusses various aspects of hair follicle biology and highlights unresolved questions and potential new research avenues, but presents no new experimental findings.

This review discusses current airway regeneration research efforts and reports no new experimental results, highlighting the need for clinical interventions to enhance airway repair.

This report concludes that no cause and effect relationship has been established between consuming KF2BL20 and maintaining normal hair in healthy adults.

This case report described a facial hairline tumor initially diagnosed as a sebaceous cyst but ultimately confirmed as a rare Proliferating Pilar Tumor with focal malignancies upon histopathological examination.
