Gynostemma pentaphyllum for Hair Health
-
Last April I posted a study Gynostemma pentaphyllum (Jiaogulan) promotes Hair Growth in mice
The image in the opening post was quite busy. Here is a section (of the image and of the mice) from Figure 1 of the study showing Jiaogulan's effect on the anagen phase of hair growth in mice.
This new study below indicates that there are also positive effects in human hair growth.
Methods: This randomized, double-blind, placebo-controlled trial involved 100 eligible adults aged 19–60 years who were randomly allocated to either the GP or placebo group. Participants consumed 340 mL/day of the test product for 24 weeks. The primary outcomes included hair elasticity, density, diameter, glossiness, and subjective satisfaction. Safety was evaluated through laboratory tests and adverse event monitoring. Results: After 24 weeks, the GP group showed a threefold increase in hair elasticity and density and a fourfold increase in hair diameter compared to the placebo group. The subjective satisfaction scores corroborated these findings: the GP users reported better outcomes in terms of reducing hair damage and dryness. No significant differences in hair glossiness were observed based on the instrumental and visual assessments (p > 0.05). The safety evaluations revealed no severe adverse events. All the safety evaluation metrics demonstrated no significant abnormalities. Conclusions: This study provides compelling evidence of the efficacy of GP extract in enhancing hair health, demonstrating both significant functional improvements and an excellent safety profile. These findings substantiate its potential as a promising functional food ingredient for comprehensive hair care interventions.
