Redensyl
Redensyl is a commercial cosmetic ingredient blend marketed for thinning hair. It is a blend of several components, including Camellia sinensis extract, Larix europaea (larch) extract, water, glycerol as a humectant, glycine, sodium metabisulfite, and zinc chloride. Central to its action are Dihydroquercetin Glucoside (DHQG) from larch extract and Epigallocatechin Gallate Glucoside (EGCG2) from green tea (Camellia sinensis) extract, which the manufacturer says reduces IL-8 release from keratinocytes. The manufacturer claims Redensyl stimulates hair growth by activating stem cells and fibroblasts in the dermal papilla; this has not been confirmed in independent studies. The manufacturer also reports a small 12-week study in 26 men; it is unpublished, not peer-reviewed and cannot be independently checked.
No independent trial has tested Redensyl on its own. A small 2023 study in 54 men compared two combination regimens, both with PRP (Tr P et al., Cureus 2023, PMID 37292551). Because Redensyl was mixed with saw palmetto and biotin, the result does not show what Redensyl does on its own.
The community's discussions about Redensyl cover a range of experiences. Some users report improvements in hair density and scalp health after using Redensyl-containing products, while others say they've seen no changes and highlight the need for real evidence to substantiate its efficacy conclusively.
Redensyl is not a proven treatment for hair loss. Independent clinical trials would be needed to know whether it has any effect.
