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

In this preprint, an integrative regenerative protocol involving microneedling, plant-derived exosomes, and other therapies was used to treat androgenetic alopecia in an elderly woman, resulting in improved hair density and scalp coverage.

This preprint reports meaningful improvements in hair density and scalp coverage in an elderly female with androgenetic alopecia treated through an integrative regenerative protocol, involving microneedling and plant-derived exosomes, among other non-pharmacological interventions focusing on cellular senescence pathways.

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 case study of a 2-month-old boy with maple syrup urine disease highlights the dangers of restricting branched-chain amino acid intake, as it led to acrodermatitis dysmetabolica-like skin eruptions and hair loss, later resolved with careful dietary adjustments and monitoring.

New patents include innovations in skin and hair care, disease treatment, plant stress tolerance, and protein purification.

This study developed a reliable RP-HPLC-DAD method, finding that amino acid concentrations in bleached hair decrease with higher hydrogen peroxide levels, notably affecting cystine.

This study found that topical application of copper (II) albumin complex improved healing signs in rats with full thickness thermal burns, enhancing antioxidant, anti-inflammatory, and pain modulating effects.

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 study found that arginine-loaded lipidic nanoparticles improved hair follicle growth in male hamsters more effectively than an aqueous arginine solution.

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 article discusses advancements in proteomic and metabolomic analysis techniques for studying hair damage but provides no new clinical results; the authors express interest in applying metabolomics to develop strategies for reducing hair damage from chemical treatments.

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

This study observed that amino acid uptake into wool follicles varies significantly, with cysteine showing the highest uptake rate, suggesting specialized transport systems that may influence wool growth.

This study found that patients with tropical chronic pancreatitis exhibited significantly reduced plasma amino acid levels and antioxidant capacity, with folate deficiency identified as a key factor in hyperhomocysteinemia.

This study found that the purified compound VB1 from Vitex negundo seeds may reduce UVA-induced skin aging by targeting MAPK1 and demonstrated its potential in mice.

This article describes a clinical case of a 67-year-old patient with telogen effluvium treated with a supplement containing amino acids, vitamin E, iron, and Serenoa repens, but reports no new clinical findings.

This case study found that a 7-year-old girl's crystalline cataract had sulfur-containing amino acids likely cystine, and was associated with abnormal hair conditions.

This case report describes two patients with trichothiodystrophy who exhibited a different pattern of hair protein composition changes, suggesting a subgroup of TTD characterized by partial loss of high-sulfur proteins without significant alteration in their amino acid composition.

This study found that isotretinoin, a drug commonly used for acne, inhibits polyamine transport in Trypanosoma cruzi, leading to trypanocidal effects, and suggests its potential as a treatment for Chagas disease without affecting mammalian cell viability.

Repetin is a protein involved in skin and hair development, binding calcium and compensating for other proteins when needed.

This study found that acellular dermal matrix scaffolds may facilitate full-thickness skin wound healing by promoting a pro-regenerative immune response through M2 macrophage polarization via the Lamtor1 pathway.

This study extracted water-soluble keratin particles from chicken feathers and verified their structural properties, observing no irritative potential on hen's eggs and positive physiological effects on human skin cells, suggesting their suitability for use on damaged or irritated skin.

In this study, researchers extracted soluble keratin proteins from chicken feathers and found they maintain structural integrity with potential uses for damaged skin, exhibiting no irritative effects in ex vivo settings on hen's eggs.

This study reported that the PTGER2 gene is strongly expressed in cashmere goat skin and its expression tends to decrease from the anagen to telogen stages of the hair follicle cycle.

This study identified a novel gene, hacl-1, that is specifically expressed in the hair follicles of ICR mouse skin and is associated with their active state.

In this study, grade 5 learners preferred Edamame snacks over their usual sweet-flavored snacks, and different roasting methods did not significantly change the nutritional quality of Edamame beans.

This study analyzes contemporary theories and practices to understand key factors influencing the development of the examined phenomenon, proposing trends and practical applications for researchers and practitioners, while acknowledging study limitations and suggesting future research directions.

This study found that dutasteride-loaded nanostructured lipid carriers coated with a stearic acid-chitosan oligomer are stable, less cytotoxic, and suitable for topical delivery to promote hair growth.

This study found that Annurca apple polyphenolic extracts reprogram hair follicle metabolism in mice, enhancing mitochondrial activity and keratin production while inhibiting some metabolic pathways.
