Both methods improve hair density and thickness; double-spin may be more effective.

No link found between new male baldness genes and female hair loss.

Finasteride is a medicine used to treat enlarged prostate and prostate cancer, and it works by changing how testosterone works in the body.

In this study, researchers found that the expression of vimentin, desmin, and laminin in rat skin contributes to cell structure and tissue integrity, with varying reactions across different cell types.

In this study, compound glycyrrhizin promoted hair regrowth in a testosterone-induced alopecia mouse model and increased human hair dermal papilla cell proliferation, likely through activating the Wnt/β-catenin pathway.

This study found that using induced pluripotent stem cell-derived mesenchymal stem cells with acellular nerve allografts significantly improved axon regeneration and functional recovery in rats with sciatic nerve injuries, suggesting a promising approach for clinical nerve repair therapies.

This study observed that human dental pulp stem cells can differentiate into adipocytes and osteocytes, but their potential for neural differentiation remains uncertain due to similar responses seen in undifferentiated cells.

This case report documents unilateral madarosis and facial alopecia as potential adverse effects of botulinum A toxin injections in a patient treated for left oromandibular dystonia.

In a study using a mouse model of diabetes, chitosan-based hydrogels increased healing markers and improved wound closure and tissue repair compared to untreated wounds, but human efficacy needs further validation.

This study found that in first-line treatment of metastatic breast cancer, pegylated liposomal doxorubicin (PLD) provided similar progression-free survival to doxorubicin with significantly less cardiotoxicity.

This study found that activating the Sonic hedgehog pathway in scarring wounds can remodel the dermis to promote hair follicle regeneration, highlighting a potential new approach to enhance healing.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

In this study, petroleum ether extract of Citrullus colocynthis fruit effectively promoted hair growth in a mouse model of androgen-induced alopecia, showing comparable results to the standard treatment, finasteride.

This research highlights the potential of using bioactive silk-based nanofiber dressings to improve the healing of diabetic wounds, suggesting that further studies are needed to refine these formulations and confirm their effectiveness in larger clinical trials.

This study found that subcutaneous injections of guanethidine or 6-hydroxydopamine induced premature hair growth in mice, suggesting a role for sympathetic nerves in hair growth control.

This study reports new cellular features and complex interaction systems in fiber differentiation, indicating more intricate cellular organization than previously recognized, including features like mast cells and primary cilia.

This study observed that the catagen phase in hairless mice displayed a slower shortening of the mutant epithelial column, resulting in longer total follicle length and abnormalities in the connective tissue sheath and glassy membrane.

This review discusses the role of extracellular vesicles in bone regeneration and their potential as therapeutics, highlighting challenges like standardization and safety for clinical application, but it reports no new clinical results.

This study found that wool fiber surfaces damaged in processing tended to have cellular debris adhering to them, while undamaged surfaces did not show this interaction.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.

This study identified the presence of recognizable organelles, such as lysosomes and mitochondria, in both the keratinized fiber and the hardened inner root sheath of the Romney wool follicle.

This study found that certain steroidal compounds, especially 10a–10c, demonstrated strong antiandrogenic activity by binding to the androgen receptor and reducing prostate weight in a hamster model.

This review discusses the association between emotional stress-related neuropeptides and the pathogenesis of alopecia areata, reporting no new experimental findings.

This study found that virgin coconut oil improved skin inflammation and symptoms of seborrheic dermatitis in rats, particularly at a dose of 10 mg/kg, by reversing alterations in antioxidant and inflammatory markers.

In this laboratory study, Cucumis melo var. makuwa leaf extract significantly reduced DHT-induced apoptosis in human dermal papilla cells by modulating androgen receptor activity and gene expression, suggesting potential as a therapy for androgenetic alopecia.

In this study, researchers developed a simplified and reliable method to prepare human hair shaft samples, achieving over 75% protein extraction efficiency and improved keratin sequence coverage, with the approach showing high reproducibility across different labs and operators.

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.
