This study reports on the biochemical characteristics of S100A3 protein in human hair cuticle, notably finding its N-terminal methionine is acetylated and has a slightly lower isoelectric point compared to the recombinant version.

This review summarizes the potential of N-acetyl-cysteine in managing diseases linked to redox imbalance, discussing its effects from cellular mechanisms to clinical applications, though further research is suggested for broader use.

This review discusses the use of methotrexate for pediatric dermatoses and reports increased use in certain conditions like psoriasis, but mainly isolated case reports for others.

This study observed that while betaine supplementation decreases total homocysteine and increases methionine levels in a mouse model of CBS deficiency, it is not as effective as methionine restriction in reversing associated phenotypes.

This article reviews the role of enzymatic processes in drug and toxin metabolism, emphasizing their impact on solubility and elimination, without presenting new clinical findings.

This review discusses the potential role of oxidative stress in hair graying and age-related alopecia, emphasizing the need for new strategies to counteract these effects, but reports no new results.

This review explores how androgens and growth hormone influence the development of terminal hairs and sebaceous glands, attributing variability in hirsutism and acne to differing genetic sensitivities to androgens, but reports no new experimental data.

Platelet-Rich Plasma (PRP) treatment may increase hair growth for genetic hair loss, but more research is needed to confirm this.

This review discusses the development and types of hair and nails as skin appendages and reports no new research findings.

In this randomized controlled trial, the nutritional supplement PPT5 α was associated with increased terminal hair percentages and improved self-assessed hair parameters in women with early-stage androgenetic alopecia.

This study found cutaneous keratinic amyloid deposition in dogs and identified cytokeratin 5 as an amyloid precursor protein, revealing new insights into the etiology of cutaneous amyloidosis.

This review discusses the roles of metabolism, reactive oxygen species, intracellular pH, and cell morphology in influencing cell fate decisions during stem cell differentiation but reports no new experimental results.

Testosterone metabolism in balding scalp cells may not be the main cause of hair loss.

This study reports that compound heterozygous loss-of-function mutations in the HEPHL1 gene in a child were associated with abnormal hair and cognitive issues, linking altered ferroxidase activity to hair disorders.

This article reviews the regulation and roles of spermidine/spermine-N(1)-acetyltransferase (SSAT) in polyamine metabolism and its potential as a target in cancer and other diseases, without reporting new experimental results.

In this study, researchers observed that graded calorie restriction in mice led to changes in stable isotope ratios and elemental content in bone collagen and hair keratin, potentially indicating intensified mobilization of endogenous proteins and altered bone collagen structure with increased dietary stress.

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

This review summarizes the antioxidant and anticarcinogenic properties of Indian Gooseberry, its phytochemical composition, and its use in traditional Ayurvedic medicine, but reports no new clinical results.

This review discusses the broader roles of angiogenic factors, like VEGFs and FGFs, beyond angiogenesis, highlighting their involvement in various biological and pathological processes.

This study discovered that in *Drosophila*, knockdown of specific storage proteins in adipocytes decreased germline stem cell maintenance, implicating a role for these proteins in adult tissue regulation.

This article reviews the role of factor Xa inhibitors like Rivaroxaban and suggests they may eventually replace vitamin K antagonists, but their side effects require further clarification.

This study demonstrated that antigens from the skin bacterium Staphylococcus epidermidis can stimulate CD8+ T cells, which in turn enhance wound healing.

This study reports that permanent and severe alopecia is a newly identified complication of the FEC 100–docetaxel regimen used for adjuvant breast cancer treatment.

This study explores the complex and not yet fully understood causes of premature hair greying, noting genetic factors such as Pax3 and MITE genes, potential defects in melanin transfer, and associations with certain syndromes, while stating that effective treatments are currently lacking.

This study found that inhibiting arachidonate 12-lipoxygenase (ALOX12) may enhance hair cuticle maturation by increasing S100A3 protein citrullination and promoting cuticular differentiation in isolated human hair follicles.

This study found that adding microneedling to minoxidil treatment significantly improved hair growth in men with androgenetic alopecia compared to minoxidil alone across all assessed measures.

This study identified 30 new compounds with significant androgen receptor binding affinity through a combination of virtual screening and in vitro testing.

This study found that regio-specific hydroxylation of cyclosporine A in Sebekia benihana is mediated by the cytochrome P450 hydroxylase CYP-sb21, suggesting potential biotechnological applications for hair growth promotion without immunosuppressive effects.

This study reports that polyphenols from Annurca apples may safely promote hair growth and protect against chemotherapy-induced alopecia without interfering with chemotherapy regimens.

This study found that an imbalance of selenium in a C57BL/6 mouse model led to hair loss with color change and was linked with changes in hair follicle apoptosis markers.
