... hanol, Ol. Rosae, Aquades. The method of the study an experimental method with extraction by maceration for 5 days and remaceration for 2 days using 96% ethanol as solvent. Evaluation of Hair Tonic preparations includes homogeneity, pH, organoleptic, viscosity, irritation, preference, and hair growth effectiveness test. The effectiveness test on hair growth in rabbits was carried out on 5 rabbits with 5 treatment groups, namely, positive control group Hair Tonic nature, negative control group, 5% concentration group, 10% concentration group, and 15% concentration group. The analysis of the data on growth testing using One Way Anova. Hair growth data on day 12 were positive control 0.95 mm, negative control 0.03 mm, formula 1 (5%) 0.08 mm, formula 2 (10%) 0.13 mm, formula 3 (15%) 0.83mm. The best formula to treat hair loss is hair tonic with a concentration of 15% nilam leaf ethanol extract. It can be concluded that the greater the concentration of nilam leaf extract given to each treatment, the faster the hair growth.
