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 study reported that the tested hair lotion significantly reduced hair loss and accelerated recovery in women with acute telogen effluvium compared to a mild shampoo alone.

This study found that overexpression of the enzyme spermidine/spermine N1-acetyltransferase in mice was associated with increased fat oxidation and a leaner phenotype, while knock-out mice exhibited increased fat accumulation.

This study found that N-acetyl-cysteine alone or combined with minoxidil improved hair parameters in men with early-onset androgenetic alopecia, with tolerable side effects.

RV3466F lotion significantly reduces hair loss and improves acute telogen effluvium.

This review discusses natural and botanical products examined for treating alopecia and reports no clinical results; the authors note growing research interest in these treatments.

This article reviews treatment approaches for trichotillomania, emphasizing differences from OCD therapies and recommending specific management strategies, without providing new experimental findings.

This study explored the carbohydrate composition of plasma cell membranes in human embryonic epidermis over various gestational ages and found specific patterns that may inform future diagnostic and therapeutic approaches for dermatoses.

In this study, the administration of indole-based compounds, particularly L-Tryptophan and Tryptophol, to a PCOS-induced rat model resulted in an increased number of healthy ovarian follicles and a reduction in ovarian cysts compared to untreated rats, suggesting potential therapeutic efficacy.

This review discusses potential agents, including acetyl-L-carnitine and vitamins, for repurposing in managing chemotherapy-induced peripheral neuropathy and reports no clinical results; the authors emphasize the need for further research.

This study found that N-acetyl-glucosamine-loaded nanostructured lipid carriers showed promise for skin lightening in healthy volunteers by reducing melanin distribution.

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 paper discusses mechanisms by which various chemicals disrupt male sexual differentiation, concluding that mixture risk assessments should include a broader set of compounds beyond phthalates to address cumulative reproductive health risks.

In this randomized double-blind study, 160 adults with alopecia areata showed significant improvements in hair loss severity after using a bioactive peptide cosmetic product that mimics platelet-rich plasma, while the placebo group showed no significant change, underlining the treatment's potential effectiveness.

Human hair contains a substance that shows blood group A activity.

This review discusses recent findings on the epigenetic regulation of adult stem cells and cancer stem cells, highlighting shared and distinct features, and reports no new clinical results.

This study demonstrates that Puerariae Lobatae Radix may regulate skin lipid metabolism by inhibiting sebaceous gland growth and reducing triglyceride secretion, highlighting its therapeutic potential for sebaceous gland-related conditions.

In this randomized controlled study, the researchers found that an herbal extract combination showed similar efficacy to 3% minoxidil solution in treating androgenetic alopecia over 24 weeks, with no significant safety concerns, suggesting it might be a viable alternative treatment.

This study found that N-acetyl cysteine and metformin had equal effects on clinical outcomes in anovulatory infertile women with PCOS, but NAC was better tolerated with fewer side effects.

This review examines how epigenetic dysregulation affects adult stem cell function, noting that impacts range from minor to serious disruptions in tissue homeostasis and potential cancer development.

This study found that overexpression of the enzyme SSAT in a mouse model significantly reduced prostate tumor size and progression, suggesting it could be a promising strategy against prostate cancer.

This study identified certain benzopyran derivatives with a bulky tert-butyloxycarbonylamino group as effective KATP channel openers that inhibit insulin secretion in rat pancreatic islets.

In this study, inducible whole-body Acly-knockout mice revealed that ACLY is essential for skin homeostasis, as its deficiency led to increased sebum production and skin abnormalities, indicating a vital role for cytosolic acetyl-CoA synthesis in preserving skin barrier integrity and systemic lipid regulation.

This article reviews the therapeutic use of carnitine derivatives for re-establishing mitochondrial functionality in aging and reports no new clinical results.

In this study, periodic exposure to red light in aged mice led to increased histone acetylation and activated mitochondrial fatty acid oxidation, which collectively mitigated cellular aging by modulating metabolism, inflammation, and gene expression.

This study successfully synthesized acetyl tetrapeptide-3 on a laboratory scale with over 56% yield and 100% purity, supporting its use in developing hair loss and scalp care products.

This study analyzed the structure and dynamics of ketoconazole, revealing how its molecular characteristics, such as spin-lattice relaxation time and chemical shift anisotropy, are influenced by π-π stacking interactions and different carbon site environments.

This study found that the PPAR-γ modulator AGED can reverse epithelial-mesenchymal transition in hair follicles affected by lichen planopilaris ex vivo, suggesting potential for treating scarring alopecias.

This review discusses trichotillomania and traction alopecia, focusing on their clinical features, diagnostic criteria, and treatment options, but it reports no new research findings.

In this study, L-methionine and L-serine application was observed to have the most significant effect on hair weight and root length, followed by acetyl L-methionine and L-serine, while glutathione inhibited growth.
