Abstract

This study aims to analyze the impact of using heat styling tools such as flat irons and hair dryers on hair health through the implementation of the Project-Based Learning (PjBL) model in the Hair Straightening course. The method used is descriptive quantitative, with data collected through questionnaires distributed to eight student clients participating in the learning project. Data analysis was conducted using Pearson correlation test, linear regression, and Paired Sample T-Test. The results showed a positive and significant relationship between the frequency of heat tool usage and the level of hair damage (r = 0.785; p < 0.05). In addition, heat styling tools contributed 61.6% to changes in hair condition (R² = 0.616), and there was a significant difference between hair conditions before and after using the tools (t = 5.321; p < 0.05). These findings confirm that excessive use of heat styling tools has a negative impact on hair health. Therefore, education through project-based learning practices is needed to encourage more wise and safe use of styling tools.

Abstract

This study investigates the impact of Augmented Reality (AR)-based learning media on cosmetology students’ practical skills in hair curling. Employing a quasi-experimental design with 28 participants divided into experimental and control groups, the experimental group received instruction through AR-based media, while the control group followed conventional teaching methods. The study aimed to assess whether AR-based learning media could improve students' technical performance and enhance independent practice. Findings reveal that AR substantially improved students’ performance, with a large effect size, as demonstrated by significantly higher posttest scores in the experimental group. The novelty of this study lies in extending AR applications to cosmetology education, an area where empirical evidence is still scarce. Previous studies have explored AR in various educational contexts; however, its application in vocational training, particularly in cosmetology, remains underexplored. The results highlight the potential of AR as an innovative tool for enhancing vocational practice, providing practical implications for instructors, students, and institutions. AR can serve as an effective supplementary tool to traditional methods, especially in procedural learning contexts. This study also lays the groundwork for future research, encouraging the application of AR in other cosmetology practices and comparing it with other immersive technologies such as Virtual Reality (VR).
