Abstract

Background: Natural remedies for treating dandruff are becoming popular.

Materials and methods: A randomized, double-blind, placebo-controlled, split-head efficacy evaluation was conducted 30 Thai volunteers aged 20-60 years experiencing dandruff measured at level 3 on D-Squame® scale. An easy to use hair tonic containing essential oil of lemongrass (Cymbopogon flexuosus) active against lipophilic yeasts was developed and then evaluated for efficacy and preference. The base formulation with the significantly highest preference (p < 0.05) was stowed with the oil at 5, 10 or 15%. Subjects applied the formulation twice a day, and an efficacy assessment with D-Squame® scale was conducted on days 7 and 14 of application.

Results: The application of lemongrass oil hair tonics with 5, 10, or 15% reduced dandruff significant (p < 0.005) at day 7 (33, 75, and 51%) and increased the effect even more (p < 0.005) at day 14 (52, 81, and 74%).

Conclusion: The hair tonic formulation with 10% of lemongrass oil seems to be the most effective preparation.
