Scientists made glow-in-the-dark dots from human hair that can detect iron, prevent counterfeiting, and reveal fingerprints.

In this study, quercitrin was reported to promote hair growth and cell viability in cultured human dermal papilla cells by enhancing cellular energy metabolism and growth factor production via MAPK/CREB signaling.

This study establishes a robust analytical method using mass spectrometry to comprehensively identify 170 chemical compounds in Xiaoban Kangfu capsules for enhanced quality control.

In this study, dynamic hyaluronic acid hydrogels with properties like injectability and controlled degradation were developed to enhance healing and remodeling of diabetic wounds, achieving effects such as inflammation reduction, increased angiogenesis, and neovascularization, leading to complete wound healing.

This study found that hypaphorine alters cytoskeletal organization in Eucalyptus globulus root hairs, contributing to reduced root hair elongation by possibly disrupting vesicle delivery needed for growth.

This study successfully developed and optimized ethanol-free microemulsion systems for the transdermal delivery of finasteride, showing that the predicted optimal formulations had physicochemical characteristics close to estimated values, without significant damage to treated hair fibers.

This study suggests that 9-Octadecenoic acid (Z)-, 2,3-dihydroxypropyl ester from African Yam bean seeds may inhibit the human 5α-reductase II enzyme, potentially helping manage BPH, although further studies are needed.

This study developed and tested a new injectable hydrogel for chronic diabetic wounds, reporting significant improvements in wound healing through enhanced angiogenesis, epithelization, and reduction of inflammation and infection in animal models.

This study found that glycyrrhetinic acid, derived from licorice, may help alleviate acne symptoms by regulating lipid synthesis and inflammatory responses through multiple pathways, as observed in both in vitro and in vivo settings.

This study found that Centipeda minima extract promotes hair growth by activating Wnt/β-catenin, ERK, and JNK signaling pathways in human hair follicle dermal papilla cells.

In this study, Cyanidin 3-O-arabinoside was found to protect against DHT-induced dermal papilla cell senescence and mitochondrial dysfunction in androgenetic alopecia, restoring hair growth in mouse models.

This study observed that tannic acid significantly reduced hair shedding by 56.2% over seven days in human participants when used as a coating for controlled release of active compounds to hair follicles.

This study found that upcycled postbiotic cell-free supernatants from Limosilactobacillus fermentum MG901 and MG4237 protected human dermal papilla cells from oxidative stress, enhancing wound-healing capacity and mitochondrial function, suggesting potential as a sustainable cosmetic ingredient for hair loss alleviation.

This study found that extracts from plants like onion peel and walnut possess strong antioxidant properties, making them promising eco-friendly alternatives to synthetic hair dyes, delivering vibrant colors and better wash fastness when combined with oxalic acid.

In this study, herbal extracts were associated with increased hair regrowth in mice when compared to the negative and vehicle control groups, potentially due to enhanced activity of certain enzymes and growth factors.

This study found that a hydrogel containing icariin enhanced wound healing and hair-follicle regeneration in vivo by promoting M2 macrophage polarization and modulating the BMP pathway, with treated skin defects showing improved recovery and new hair follicle development compared to untreated defects.

In this study, researchers identified nine FDA-approved drugs that activate the Wnt signaling pathway, with Aminoacridine, especially when combined with Minoxidil, showing promising effects on hair and nail growth in mice, suggesting potential treatments for hair and nail loss pending further clinical trials.

This study found that DHA, a derivative of artemisinin, shows potential as a cosmetic ingredient due to its anti-aging, anti-hair loss, antibacterial, whitening, and anti-glycation activities.

In this study, synchrotron-powered infrared microscopy revealed that hair follicles are a favored penetration pathway for cyanophenol and ethylhexyl methoxycinnamate in human skin, without altering protein secondary structure.

In this experimental study using rabbits, the researchers evaluated hair tonic formulations containing cinnamon essential oil and virgin coconut oil, finding that formula 3 had hair growth activity exceeding the positive control, though overall growth activity differences were not statistically significant.

This structural study reports on the crystal properties of a compound used for treating alopecia, revealing different conformations and nitrogen hybridization in its piperidine rings.

This study found that using natural polyphenol cross-linkers like tannic acid and green tea extract during perm treatments improved perming efficiency, wave maintenance, and hair protection compared to a control group.

This study found that camphor and similar compounds depress neural activity in rat mechanoreceptors, suggesting that their effects may not be mediated through TRP channels.

This study found that oxidative treatment with peracetic acid dissociates some disulfide bonds in human hair fibers while maintaining the crystalline structure, suggesting different mechanisms stabilize different regions of intermediate filaments.

This study focuses on improving the detection and characterization of an enzyme in guinea pig hair follicles that converts arginine to citrulline, highlighting challenges with assay sensitivity and reproducibility.

In this study, the alcoholic extract DN106212 from Centipeda minima was shown to be more effective in promoting hair growth in C57BL/6 mice compared to dimethyl sulfoxide and tofacitinib, suggesting its potential as a natural hair growth agent.

This study found that compounds isolated from Indian medicinal plants showed good to moderate hair growth activity in vivo compared to minoxidil.
