This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

This review identifies cysteine's central role in hair growth and its potential impact on Alopecia Areata's pathogenesis, suggesting examination of cysteine metabolism might clarify the disease's underlying mechanisms and lead to new treatments.

In this study, combined treatment with transglutaminase and keratin significantly repaired damaged hair by improving its structural properties, reducing swelling, and enhancing crosslink activities, as evidenced by microscopy and spectroscopy analyses.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

Certain skin drugs and topical agents, including some natural extracts and fragrances, can cause allergic reactions. Some hair dyes and extensions, as well as minoxidil, a hair growth treatment, can also cause allergies. Botulinum toxin A can effectively reduce sweat but may have temporary side effects.

This study presents computational modeling and experimental analysis of the HGT protein KAP8.1, identifying key structural features that may influence hair's response to environmental conditions.

This study reported that the calculated and experimental electronic and vibrational properties of minoxidil were in good agreement, providing detailed insights into its molecular structure and thermal behaviors.

This study developed a biodegradable nonwoven textile using a starch-based biopolymer and fruit extracts, resulting in materials that are stronger, more hydrophilic, and capable of releasing beneficial compounds over 72 hours, positioning them for potential use in medical, healthcare, and cosmetic applications.

This study found that injectable gelatin/metal/tea polyphenol double nanonetworks significantly accelerated wound healing in diabetic wounds by enhancing cell migration and providing anti-inflammatory and antioxidant properties, without detectable cytotoxicity in tests.

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 investigated the secretome of adipose mesenchymal stem cells and fibroblasts used in skin care products, finding 16 therapeutic pathways involving numerous signaling mechanisms, which may offer skin benefits through anti-inflammatory and regenerative effects.

This study found that a hair tonic containing 1% teak leaf extract significantly increased hair growth and user satisfaction in men with androgenic alopecia after 24 weeks, without causing adverse effects, and was comparable to the standard treatment, minoxidil.

This study found that treating hair with aqueous KCN converts disulfide bonds to monosulfide crosslinks, affecting the elasticity and crosslink distribution in hair microstructures.

This article discusses a hypothetical model of androgenic hair trichophore composed of various chemical components, but it reports no new empirical findings; the authors emphasize the model's potential impact on hair cosmetics.

This study found that a shampoo containing quaternized wheat protein hydrolysate can effectively improve hair recovery by smoothing and compacting damaged hair surfaces, thanks to modifications that enhance protein adherence and disulfide bond formation at pH levels typical in hair care products.

This study found that the cocrystal of mycophenolic acid with isonicotinamide significantly improved solubility and dissolution rate, while two other cocrystals showed decreased performance in these areas.

This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

This review highlights the lack of research on Afro-textured hair, emphasizing the need for better understanding of its genetic traits and molecular structure to develop more effective hair care solutions.

This study on Sdr16c5/Sdr16c6-null mice found that inactivating these genes significantly increased Meibomian gland secretions and altered lipid profiles but had a subtle impact on sebogenesis, suggesting the genes control a bifurcation point in meibogenesis pathways.

This review outlines the role of dermal fibroblasts in wound healing and highlights their potential in developing new cellular therapies, but reports no new clinical results.

The authors conclude that optimizing hair shaft production and appearance may best be achieved by integrating biological, chemical, and physical intervention strategies.

This study reported that fermented grapeseed oil may enhance hair permeability and improve strength and color retention in chemically treated hair compared to regular grapeseed or silicone oils.

This study found that novel thiol-reactive cross-linking agents, particularly APA, significantly improved the tensile strength and elasticity of human hair fibers by effectively regenerating disulfide bridges, with potential applications for advanced hair repair treatments in the cosmetic industry.

This study developed a novel hair-straightening shampoo incorporating a polyphenol–inorganic sulfate redox agent, finding that it effectively straightens hair while enhancing strength and reducing damage due to its protective polyphenol coating.

In this study, a bleaching protocol was developed to evaluate hair repair products, revealing that K18® and Olaplex® improve hair brightness and lightness, with distinct impacts on hair fiber properties.

This review summarizes recent genetic research on hidradenitis suppurativa, highlighting potential therapeutic targets and genetic mutations, but reports no new clinical findings.

This study found that thioglycolic acid molecules in hair treatments are primarily located in intrafibrillar unordered areas, where they redistribute disulfide bonds.

In this study, APC collagen peptides were observed to enhance hair elasticity and gloss in human hair follicles by increasing amino acid and lipid component levels, suggesting their potential benefits for improving hair qualities.

This study reported that disrupting ephrin-Eph interactions in adult mouse skin doubled cell proliferation in the hair follicle and epidermis, suggesting ephrins as negative regulators of proliferation.

This study describes Hg(OTf)2 as a new and efficient catalyst for various organic synthesis reactions, including alkyne hydration and C–C bond forming cyclizations.
