The best mix of propylene glycol and sorbitol was found for a cream to prevent hair loss using saw palmetto extract.
Saw palmetto cream for hair loss works better with glycerol and sorbitol.
This study found that glycerol most significantly influenced the spreadability and initial viscosity of a saw palmetto anti-hair loss cream, while PEG 400 predominantly affected viscosity changes over time.
In this study, the researchers found that glycerol strongly influenced the physical characteristics of an anti hair loss cream containing Saw Palmetto extract, notably improving its spreadability, viscosity, and stability without causing skin irritation.
This study found that conditioned medium from human placental cells or tissue promoted angiogenesis in HUVECs in vitro, with early-pregnancy placental cells and whole placental tissue showing more significant effects.
