This study found that certain tandem repeats predict darker hair color across diverse ancestry groups and can contribute to a polygenic score for hair color, independent of SNP variation.

This study explored how long non-coding RNA mediates the effects of FGF5 on the hair follicle development and villus growth of Liaoning cashmere goats.

This study found that fish oil supplementation in male Wistar albino rats helped maintain hair shaft structure and improved amino acid composition, while reducing harmful protein compounds associated with diabetes and hypercholesterolemia.

In this study, distinct metabolic profiles were identified in women with PCOS, suggesting potential biomarkers for diagnosis based on changes in lipid and androgen metabolism.

This review highlights the challenges in identifying histological features of adverse reactions to soft tissue fillers and emphasizes the need for increased awareness due to product uncertainty and delayed reactions.

In this study, researchers developed a dissolvable microneedle patch combining HA-TEMPO and Portulaca oleracea L.-derived nanoparticles, which effectively reduced oxidative stress and inflammation in an atopic dermatitis model while restoring immune balance, suggesting a promising treatment strategy.

This study used a zebrafish model and advanced mass spectrometry to identify 11 metabolites of epristeride, revealing significant effects on purine metabolism and aromatic amino acid biosynthesis, which may aid in developing anti-doping detection methods.

This case report describes a 2-year-old boy diagnosed with trichothiodystrophy, characterized by fragile hair, intellectual damage, diminished fertility, and short stature.

This study suggests that porphyra-334 may have antiaging properties, promoting collagen synthesis, improving periorbital wrinkles, and supporting hair follicle growth through gene regulation.

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 chapter reviews emerging side effects of various nutritional supplements and alternative medicine practices, highlighting potential toxicities and stressing the need for careful identification and management by healthcare professionals.

This study found that cotreatment with graphene oxide and indole-3-acetic acid significantly inhibited root development in Brassica napus, with the inhibition increasing as indole-3-acetic acid concentration rose.

This study developed a rapid and accurate spectrophotometric method using diazotized sulfanilic acid to measure minoxidil in both pharmaceutical formulations and pure form, demonstrating high precision and linearity within a concentration range of 5-40 μg/ml.

In this study, researchers developed a polyphenol–amino acid nanozyme capable of controlled hydrogen peroxide delivery, which effectively activated hair follicles via oxidative stress in a mouse model, suggesting a potential non-pharmacological treatment for alopecia.

This study found that nutritional deficiencies, particularly in amino acids and certain micronutrients, are common in individuals with hair loss across all types of alopecia.

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 study found that hair samples from children with kwashiorkor or marasmic kwashiorkor had about 20% less cystine compared to one child with adequate protein nutrition, suggesting the need for further research.

This study developed a mathematical model indicating that the amino acid sequences of intermediate filament proteins, rather than flexibility differences, significantly impact assembly rates.

This study found that senior dogs fed amino acid-complexed and lysine-glutamic acid-complexed trace minerals had longer, faster-growing hair and increased activity compared to those fed inorganic trace minerals.

This study suggests that APC collagen peptides may accelerate hair growth and promote overall hair health by enhancing cellular proliferation and activating specific signaling pathways in human and mouse models.

This consensus paper reviews expert opinions on treating telogen effluvium but reports no new clinical findings.

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 examined hair mineral and free amino acid components in various diseases and found that when using effect size analysis, specific components related to diabetes and other conditions were identified, suggesting their potential as novel health indicators.

This study found that supplementing with 1.5% α-ketoglutaric acid significantly improved the performance, hair follicle density, and antioxidant capacity in Rex rabbits, potentially by enhancing the Wnt signaling pathway and reducing amino acid catabolism.

In this study, researchers found that using 0.75% aspartic acid as an intermediate agent for a permanent wave improved wave formation and retention compared to a control in virgin hair, also reducing cuticle damage and maintaining tensile strength.

This study developed a validated HPLC method for accurately estimating dutasteride and its related compounds in capsules, suitable for routine and stability sample analysis.

This study found that exogenous glutamic acid can promote hair growth and keratinocyte proliferation, suggesting a novel signalling pathway in the skin.

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

In this study, the researchers successfully increased dipicolinic acid production in Bacillus subtilis by genetically modifying the spoVF operon, achieving a significant productivity improvement in the culture medium.

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.
