This study evaluated the stability and effectiveness of black tea extract hair tonic in promoting hair growth using rabbits. Three formulations with different concentrations of black tea extract (1.25%, 2.5%, and 5%) were tested for physical stability and hair growth efficacy. All formulations were found to be stable. The 5% black tea extract formula (formula 3) showed the highest effectiveness, resulting in an average hair growth of 9.62 ± 0.365 mm by the 18th day. The findings suggest that black tea extract can stimulate hair growth, with the 5% concentration being the most effective.
