Extraction of Phenolic Compounds and Evaluation of the Antioxidant and Phenolic Compounds of Onion (Allium Cepa L.)

In this study, onion (Allium cepa) extracts promoted hair growth in an alopecia model in mice, with the effect appearing unrelated to the presence of the polyphenol quercetin.

This study investigates the potential of onion extract as a treatment for androgenetic alopecia by using in silico and ADME/T analyses to examine how active compounds from onions interact with the 5-alpha-reductase enzyme.

This study analyzed the bioactive compound profiles of Allium longisepalum from Iran, finding unique metabolites with potential antioxidant, allelopathic, antibacterial, anti-inflammatory, anticarcinogenic, and hair growth-enhancing properties, revealing the plant's chemical diversity and therapeutic potential.

This study aimed to formulate and evaluate a herbal gel containing Allium cepa extract for its physical properties, such as appearance, viscosity, and spreadability, but it does not report specific results or effectiveness in preventing hair loss.

In this study, topical red onion ethanol extract significantly restored cutaneous antioxidant and pro-angiogenic markers in UV-B-exposed rats, enhancing SOD and VEGF levels dose-dependently, but did not influence hair length, suggesting potential as an adjunct for hair photoaging.
