Lemongrass oil, derived from the *Cymbopogon* plant, has garnered attention as a potential treatment for dandruff. Several randomized controlled trials (RCTs) have investigated its efficacy in managing this common scalp condition. These studies aim to determine whether lemongrass oil offers a viable alternative or complementary therapy to existing dandruff treatments. The findings from these clinical trials will be crucial in assessing its potential benefits and risks.

- Protocol: A randomized, double-blind, placebo-controlled trial with 30 Thai adults (20-60 years) with moderate dandruff used a lemongrass oil hair tonic (5%, 10%, or 15%) twice daily for 14 days. Dandruff was measured using the D-Squame scale.
- Outcome: Lemongrass oil tonic significantly reduced dandruff at all concentrations (5%, 10%, 15%) by day 7 and 14 (p<0.005). The 10% concentration appeared most effective.
Research Interpretation: Summary and Conclusion
One randomized, double-blind, placebo-controlled trial (PMID 26566122) investigated the efficacy of lemongrass oil hair tonic in treating dandruff in Thai adults. The study utilized three different concentrations (5%, 10%, and 15%) of lemongrass oil applied twice daily for two weeks. Dandruff severity was assessed using the D-Squame scale. Consistent findings across all concentrations showed a statistically significant reduction in dandruff by day 7 and 14 (p<0.005). While all concentrations were effective, the 10% concentration appeared to be the most effective. Further research with larger, more diverse populations and longer follow-up periods is needed to confirm these findings and establish optimal lemongrass oil concentration and treatment duration for dandruff management. The current evidence suggests a potential benefit of lemongrass oil in reducing dandruff severity.
