The purpose of this study is to analyze a hair tonic made from pandan leaves with treatment frequencies of once a day and twice a day for two weeks.This type of research employs a quasi-experimental method. The design used is a Non-equivalent Control Group. The population for this study consists of women aged 19-24, specifically students from the Class of 2020 in Beauty and Makeup, with a sample size of 6. The data collection techniques include observation and documentation. The data analysis techniques used are normality tests, homogeneity tests, and t-tests. Based on the research results, the use of hair tonic made from pandan leaves (Pandanus amaryllifolius Roxb) as a cosmetic hair tonic for treating dandruff shows that in the indicator of the amount of flakes/dandruff, the treatment of once a day resulted in an average category of 5 (no flakes) while the treatment of twice a day resulted in an average category of 4 (significant reduction in dandruff).
