research Utilization of L-Cystine and L- and D-Methionine by Mink During the Period of Intensive Hair Growth
Mink use L-methionine and L-cystine slightly better than natural amino acids for hair growth, but D-methionine is not effective.
research Senile Hair Graying: H2O2-Mediated Oxidative Stress Affects Human Hair Color by Blunting Methionine Sulfoxide Repair
This study found that hydrogen peroxide accumulation and reduced methionine sulfoxide repair play a significant role in the oxidative damage linked to senile hair graying.
research Inhibitory Effects of Ethionine, an Analogue of Methionine, on Wool Growth
This study found that ethionine significantly inhibited wool growth in sheep, with L- and D-isomers being equally effective, but did not cause hair loss in sucking mice or rats.
research Methionine Improves Feather Follicle Development in Chick Embryos by Activating Wnt/β-Catenin Signaling
This study found that injecting L- or DL-Methionine into chick embryos increased feather growth and follicle development by activating the Wnt/β-catenin signaling pathway, with no difference between the two methionine forms.
research Oxidative Stress in Aging of Hair
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.
research In Vitro Methodology, Hormonal and Nutritional Effects, and Fiber Production in Isolated Ovine and Caprine Anagen Hair Follicles
This review discusses studies on hair growth and protein synthesis in hair follicles, highlighting the differing responses of mohair and cashmere goat follicles to signaling molecules, biotin, and amino acids, but contains no new results.
research Telogen Effluvium Treated With Serenoa Repens Supplement
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.
research Promotion of Hair Growth by Applying Sulfur Amino Acids and Other Compounds to the Skin
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.
research Effect of Various Dietary Factors on Selenium Deposition in Hair and Nails of Rats
This study observed that selenium retention in rat hair and nails was influenced by the chemical form of dietary selenium and methionine status, suggesting caution when using these tissues to assess selenium status.
research Nutrition of Women with Hair Loss During Menopause
This review discusses the role of diet in managing hair loss during menopause and reports no new clinical results; it highlights the importance of nutrients like sulfur amino acids, vitamins, and minerals.
research Prolonged Maintenance of Human Hair Follicles In Vitro in a Serum-Free Medium
In this study, isolated human hair follicles maintained prolonged growth and consistent DNA and keratin synthesis patterns in a fully defined medium for at least 9 days while preserving in vivo-like morphology.
research Effect of Quality and Quantity of Protein on Body Growth and Hair Growth of the Rat
This study found that rats fed a diet with different protein qualities and levels showed significant differences in hair cycle length, daily weight gain, and hair density.
research Cell Fate Decisions: Emerging Roles for Metabolic Signals and Cell Morphology
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.
research Effects of Different Dietary Protein Levels and DL-Methionine Supplementation on Hair Growth and Pelt Quality in Mink (Neovison Vison)
This study demonstrated that mink hair growth and pelt quality significantly depend on dietary protein levels and DL-methionine supplementation during the growing-furring period.
research The Redox Biochemistry of Human Hair Pigmentation
This article reviews the impact of H2O2-redox homeostasis on hair follicle pigmentation via tyrosinase and associated mechanisms, discussing primarily findings from murine models without providing new clinical results for humans.
research L-Carnitine-L-Tartrate Promotes Human Hair Growth In Vitro
This study found that l-carnitine stimulated hair growth in vitro by promoting proliferation and reducing apoptosis in human scalp hair follicles, suggesting potential as a treatment for hair loss.
research Dietary Supplementation With L-Glutamine Enhances Immunity and Reduces Heat Stress in Hanwoo Steers Under Heat Stress Conditions
This study found that L-glutamine supplementation in Hanwoo steers under heat stress did not affect growth performance or muscle and adipose tissue gene expression but was associated with increased immune cells and reduced HSP90 expression.
research New Therapeutics in the Management of Androgenetic Alopecia
This thesis investigates the underlying mechanisms and treatment options for androgenetic alopecia, highlighting the molecular roles of androgens and genetic predispositions, and evaluates current and emerging therapies, such as PROTACs and Janus Kinase inhibitors, to enhance patient management.
research Chemoprevention of Smoke-Induced Alopecia in Mice by Oral Administration of L-Cystine and Vitamin B6
This study found that oral administration of l-cystine with vitamin B6 effectively prevents environmental cigarette smoke-induced alopecia in mice by reducing hair bulb cell apoptosis.
research Chemoprevention of Doxorubicin-Induced Alopecia in Mice by Dietary Administration of L-Cystine and Vitamin B6
This study demonstrated that high doses of L-cystine and vitamin B6 effectively prevent doxorubicin-induced hair loss in mice.
