5α-Reductase Type 1 Inhibition of Oryza Sativa Bran Extract Prepared by Supercritical Carbon Dioxide Fluid

This study found that ethanol extract of Tubtim Chumphae rice bran downregulates SRD5A gene expression, similarly to finasteride, suggesting potential use as an anti-hair loss product.

In this study, rice bran supercritical CO2 extract demonstrated potential to promote hair growth in mice, increasing hair follicles and growth factor expression, similarly to 3% minoxidil.

This review discusses the use of supercritical carbon dioxide for extracting rice bran oil, noting its advantages over conventional methods for preserving nutrients and antioxidants, but provides no new experimental results.

This research reported that KDML105 bran extract demonstrated antioxidant activities, reduced nitric oxide production, and influenced gene expression related to the hair cycle in cultured dermal papilla cells, suggesting potential as an anti-hair loss agent by supporting the anagen phase and angiogenesis.

This study found that extracts from the rice variety Bue Bang 3 CMU, particularly the husk and bran, demonstrated antioxidant, anti-inflammatory, and anti-androgenic properties, suggesting potential use in treating androgenetic alopecia.
