January 2025 in “SSRN Electronic Journal”
December 2024 in “Biological and Pharmaceutical Bulletin” In this study, researchers found that minoxidil nanocrystals delivered using MG-MXD@NP, containing methylcellulose and gum arabic, significantly improved hair growth in mice compared to a standard minoxidil lotion, with enhanced delivery to skin tissues and increased markers of hair follicle stem cell activity.
November 2024 in “Biophysical Chemistry” This study analyzed the swelling behavior of human hair during permanent waving treatment, finding that both the microstructure and macrostructure of intermediate filaments swell simultaneously at the initial stage, and while partially destructed by reduction, they are considerably restored through oxidation.
July 2024 in “Biological and Pharmaceutical Bulletin” This study found that 18-β-Glycyrrhetinic acid, a licorice component, stimulated human hair follicle cell proliferation, inhibited testosterone 5α-reductase, and suppressed TGF-β1, suggesting potential for treating androgenetic alopecia by promoting hair growth and prolonging the anagen phase.
June 2024 in “ESMO Gastrointestinal Oncology” The BAYONET trial is a phase II study designed to assess the efficacy and safety of combining encorafenib, binimetinib, and cetuximab for patients with BRAF V600E-mutant metastatic colorectal cancer that is resistant to encorafenib plus cetuximab; results are not yet reported.
May 2024 in “Journal of functional foods” In this laboratory study, coffee bean residue extract was observed to promote the proliferation of human hair follicle dermal papilla cells by activating autophagy, showing potential for treating hair growth disorders and hair loss.
May 2024 in “Frontiers in medicine” In this study, a 3-year-old Japanese child with autosomal recessive woolly hair was found to have a distinctive irregular and rough cuticle on the hair shaft, along with a homozygous pathogenic LIPH variant, suggesting a critical role for genetic analysis in understanding rare hair conditions.
February 2024 in “Genes to Cells” This study observed that tooth loss in mice led to premature graying of hair in the interbrow region, which was possibly due to reduced stimulation of the trigeminal nerve, suggesting that decreased mastication could cause this type of hair graying.
February 2024 in “ACS applied bio materials” This study observed that keratin-based microspheres promoted hair regrowth in C57BL/6 male mice and enhanced hair growth markers in human dermal papilla cells, suggesting these particles may effectively target hair follicles to aid in hair growth.
January 2024 in “Biological & pharmaceutical bulletin” In this study, Panax ginseng extract and its ginsenosides were found to stimulate the proliferation of hair-related cells and promote the transition from the telogen to the anagen phase, enhancing hair-shaft growth by suppressing BMP4 expression in human dermal papilla cells.
November 2023 in “Biomolecules” In this study involving genetically modified rats, researchers observed that specific mutations in the vitamin D receptor affect calcium levels and bone formation, emphasizing the receptor's role in maintaining healthy bone density and its importance in regulating hair cycle and skin health.
September 2023 in “The Journal of Dermatology” In this study, injecting dermal sheath cup cells into affected areas of pattern hair loss improved hair thickness and patient-reported hair appearance in 62.9% of the participants, with better results in women, without serious side effects.
July 2023 in “International Journal of Molecular Sciences” In this study, Trapa bispinosa Roxb. pericarp extract demonstrated inhibitory effects on 5α-reductase activity both in vitro using LNCaP cells and in vivo in a mouse model of benign prostatic hyperplasia, suggesting its potential role in managing the condition.
