This study found that the optimized topical AR antagonist 39, derived from 14-P1, demonstrated potent AR antagonism and comparable efficacy to pyrilutamide in a hair-growth mouse model, with a faster onset and favorable safety profile.

In this experimental study, the researchers observed that Platycladus orientalis leaf extract promoted hair growth by enhancing dermal papilla cell proliferation and increasing growth factor expression, particularly through ACK1 activation and modulation of Wnt/β-catenin signaling pathways in cultured human cells and a 12-week topical application.

This study found that among eleven tested polymethoxyflavones, 5-hydroxy-7,4′-dimethoxyflavone was the strongest steroid 5α-reductase inhibitor and suggests potential use for benign prostatic hyperplasia treatment.

In this study, computational analysis identified six molecules, including Jamogenin, as effective in binding to the enzyme 5-alpha reductase (5-AR) from herbal extracts like nettle, saw palmetto, and fenugreek, suggesting potential for hair loss treatments.

This study found that a eupafolin nanoparticle delivery system improved water solubility and skin penetration, enhancing its antioxidant and anti-inflammatory effects against particulate matter-induced stress in skin cells.

This study developed an efficient method for converting polymeric procyanidins into high-purity oligomeric procyanidins using a semisynthetic approach combined with separation techniques.

This review from this study outlines the traditional uses, phytochemicals, and diverse pharmacological activities of Portulaca oleracea L. (purslane), suggesting its potential application in food, pharmaceuticals, and animal husbandry due to its various health benefits and nutritional properties.

This study reported that compounds from the root of Beta vulgaris, specifically 4-picoline and Betalain, showed potential as effective anti-hair loss treatments by demonstrating significant inhibitory activity against the enzyme 5α-reductase in a computational molecular docking study.

This study reports that although saw palmetto extract is marketed as a natural alternative for hair loss and prostate health, its unregulated status may pose safety and efficacy risks to consumers.

This study reported that compounds isolated from Alpinia zerumbet significantly promoted hair cell growth and exhibited anticancer activity in cell cultures, suggesting potential as treatments for alopecia and cancer.

This study found that platycodon ethanol extract showed potential as a natural ingredient for hair loss prevention by increasing radical scavenging ability, inhibiting inflammation, and affecting DHT generation in laboratory experiments.

In this study, isatin-gallate hybrids were synthesized and assessed, with compound 3b showing significant in vitro antioxidant and cytotoxic activities, and the series displaying moderate efficacy in inhibiting coronavirus activity through in silico analysis.

This study reported that Saw Palmetto, at a physiological dose, partially inhibits 5-alpha-reductase and, when combined with Lycopene, L-Arginine, and Astaxanthin, demonstrates a synergistic effect in restoring hormonal balance, reducing inflammation, and improving hair density, urinary flow, and oxidative biomarkers in related male health conditions.

This study found that compounds isolated from Osmanthus fragrans var. aurantiacus demonstrated antioxidative and anti-inflammatory activities, potentially offering therapeutic benefits for inflammatory bowel diseases by inhibiting COX-2 and iNOS enzymes and blocking ERK 1/2 MAPK signaling.

This study found that fractions of Tridax procumbens extract demonstrated significant antioxidant activity, comparable to standard ascorbic acid, in laboratory tests.

This study found that a proniosomal gel formulation of finasteride increased anagen hair count in male volunteers with androgenic alopecia by 42.85% compared to the control group.

This study found that inhaling toluene reduces core temperature in mice, with GABA receptors and neurosteroids involved at 4000 ppm, but different mechanisms contributing at 6000 ppm.

This study explored how modifying the 8-substituent of 8-bromobenzoquinolinone affects its selectivity in inhibiting both 5 alpha-reductase isozymes in the scalp.

This study found that sinapic acid promotes the browning of 3T3-L1 adipocytes and may offer therapeutic potential for obesity by influencing mitochondrial biogenesis through the p38 MAPK/CREB signaling pathway.

Some drugs for inflammation may cause psoriasis-like hair loss.

This review highlights that pomegranate leaf exhibits potential health benefits, such as anti-cancer, anti-diabetic, anti-inflammatory, and neuroprotective effects in vitro and in animal models, but calls for comprehensive human clinical trials to confirm these therapeutic benefits and ensure safety.

This study found that taxol induces apoptosis in dermal papilla cells, affecting protein expression related to biological processes and potentially contributing to taxol-induced alopecia.

This study found that nanocapsules formulated as a dispersion and applied with massage may enhance follicular uptake of clobetasol propionate while minimizing its skin penetration, offering a potential improvement over conventional treatments for scalp diseases.

In this randomized controlled trial, researchers observed that topical clobetasol propionate 0.05% was significantly more effective than topical tacrolimus 0.1% for treating alopecia areata, with a higher treatment success rate of 74.2% versus 45.2%, suggesting clobetasol as a preferred first-line topical therapy.

Hinokitiol and pantothenylethylether in hair products can cause strong allergic reactions.

This study evaluated compounds from Jatropha cordata bark, finding that a sterol mixture and n-heptyl ferulate demonstrated notable anti-inflammatory activity in murine macrophage cells without toxicity, suggesting potential for treating chronic inflammation.

The authors discussed the potential benefits of Urtica dioica and Serenoa repens for hair health, but emphasized that more concrete evidence and standardized formulations are necessary for reliable therapeutic use.

In this study, norgalanthamine was found to stimulate hair growth in cultured rat dermal papilla cells by activating the ERK 1/2, PI3K/AKT, and Wnt/β-catenin signaling pathways.
