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.

In this study, Satura® Rosta remedy was found to significantly increase hair follicle size, hair root volume, and skin thickness in mice, potentially by prolonging the anagen phase, with notable hair regrowth observed in older mice with alopecia.

This review discusses the multifunctional role of subcutaneous adipocytes, their contribution to metabolic and pathological processes, and reports no new experimental results; it suggests potential protective roles against metabolic syndrome.

This study reports that the novel small molecule IM176OUT05, by modifying stem cell metabolism, promoted hair regrowth and increased hair follicle numbers in mice.

This study found that telogen, a resting phase of the hair follicle cycle, is characterized by dynamic gene expression, including enhanced cholesterol metabolism and immune signaling, suggesting it is an active regulatory phase despite its quiescent appearance.

This study found that 650-nm red light treatment promoted hair follicle proliferation and delayed the transition from anagen to catagen in ex vivo hair follicles from androgenetic alopecia patients, with RNA-seq analysis suggesting involvement of biological processes like metabolism and leukocyte migration.

This study suggests that human hair follicles may operate their own Cori cycle, synthesizing glycogen from lactate under conditions of lactic acidosis.

This study suggests that melatonin plays a role in hair follicle function by modulating growth and pigmentation, and it may act as a protective agent in active hair growth phases.

This study found that rhamnose can restore hair-inducing gene expression in dermal papilla cells and accelerate hair follicle regeneration by promoting the hair cycle into the anagen phase, suggesting its potential therapeutic application for alopecia treatment.

This study identified a group of dermal fibroblasts near hair follicle stem cells in mice that facilitate hair regeneration by creating a biomechanically compliant extracellular matrix, enhancing stem cell activation and promoting a positive feedback loop for tissue regeneration.

This article discusses how metabolic imbalances can trigger telogen effluvium by causing hair follicles to prematurely enter the shedding phase, and includes no new research findings.

This review discusses the role of various hormones in diffuse hair loss and emphasizes the need for further research to clarify their complex interactions and potential therapeutic implications, but reports no new clinical results.

This study found that sodium butyrate, a metabolite from the HF microbiome, significantly delayed catagen onset and promoted key physiological processes in cultured human hair follicles.

This study found that autophagy activation in hair follicle stem cells shifted their metabolism to glycolysis, which promoted hair growth by initiating the hair follicle cycle.

In this study, researchers observed that metabolite expression patterns, including sugars, lipids, amino acids, and nucleotides, affect hair follicle growth in cashmere goats, with feeding practices potentially influencing these cycles via hormone and vitamin levels.

This study observed that during the rat hair cycle, DNA synthesis in dermal cells peaks during a specific growth stage, suggesting a coordinated metabolic activity with potential implications for alopecia areata research.

This study suggests that melatonin may enhance wool growth in cashmere goats by activating sulfur metabolism genes and high-sulfur protein genes, which are crucial for providing sulfur-containing amino acids needed for wool quality.

This study used scRNA-Seq to map the transcriptional changes during zebrafish hair cell regeneration, revealing distinct phases including injury response, transient regeneration gene activation, and reactivation of developmental programs.

This study found that mouse skin can produce and metabolize serotonin and N-acetylserotonin, with activity influenced by location, physiological skin status, cell type, and mouse strain.

This study found that activating autophagy in hair follicle stem cells can promote hair growth by shifting their metabolism to glycolysis, while inhibiting it led to delayed hair cycle progression.

This study identified dual epithelial and mesenchymal traits in dermal sheath cells during wound repair, suggesting they could be targeted to enhance healing.

This study highlights the crucial, multifaceted roles of fibroblasts in wound healing and various diseases, including their dysregulation in diabetic foot ulcers, underscoring the need for targeted therapies to address complications and morbidity from such chronic conditions.

Caffeine in Alpecin shampoo may help prolong hair root activity and reduce hair loss.

This study found that topical estradiol inhibits hair growth in mice by preventing the hair follicle's transition from resting to growth phase, a process reversible with an estrogen receptor antagonist.

Hair can indicate early signs of metabolic disorders, with issues like protein deficiency stopping hair growth.

In this study, DOP treatment improved hair regrowth in androgenetic alopecia by altering local steroid metabolism and follicular morphology.

This study found that cutaneous pyridoxal 5'-phosphate hydrolase activity may be carried out by an enzyme different from the classical tissue-nonspecific alkaline phosphatase in human and mouse skin.

This study found that dermal papilla cells exhibit stage-dependent variation in histone methylation during the hair follicle cycle and display distinct chromatin marker expression when transitioning to in vitro culture.

This review examines physical methods like electron paramagnetic resonance spectroscopy, Raman spectroscopy, and differential scanning calorimetry, highlighting their complementary capabilities in analyzing biomolecular structures and mycobacterial interactions with reactive oxygen species and antioxidants.

This review discusses "follicular hypoglycania" as a potential pathology in hair growth disorders and reports that proteoglycan replacement therapy may improve hair loss treatments, though it presents no new clinical trial results.
