September 2024 in “International Journal of Molecular Sciences” This study found that hot water extract of Hydrangea serrata leaf and hydrangenol promoted hair growth by enhancing 5α-reductase inhibitory activity, stimulating dermal papilla cell growth, and exhibiting anti-inflammatory and anti-androgenic effects in cell cultures, mice, and human skin organoid models.
June 2024 in “Frontiers in immunology” In this case report, an 8-year-old with severe alopecia areata and atopic dermatitis experienced significant hair regrowth and improved dermatitis symptoms after treatment with dupilumab followed by baricitinib, with no major side effects observed.
May 2024 in “International Journal of Cosmetic Science” This review highlights that hair's chemical bonds, particularly disulfide bonds, are not homogeneous, as previously thought, but instead vary in response to different cosmetic treatments, suggesting a need for further exploration of ionic bonds and hydrophobic interactions.
May 2024 in “Proteome science” This study found that the PLEE method increased hair protein extraction efficiency threefold and that bleaching hair reduced the coverage of keratin and associated proteins, leading to poorer hair quality, though it did not affect the overall protein identification.
This study found that expression and variants of the KRT84 gene are associated with important wool traits in Gansu Alpine Fine-wool sheep, suggesting its potential use as a genetic marker for wool trait selection.
This study found that basal cell carcinoma exhibits patterns of hair follicle differentiation but is stuck in telogen arrest, which can be rescued by adding noggin and TGF-β2 in vitro.
