Purpose : This study examines hair-dyeing effects and changes in the characteristics of hair texture by applying Arecae semen pigment to hair.
Methods : The Arecae semen pigment was double-boiled and applied to two samples, namely, healthy and bleached hair. The samples were heat-treated and left in natural condition for different hours. The samples were measured before and after application and comparatively analyzed. To quantify the hair-dyeing effects, the L*, a*, and b* values as well as fading were measured using a color-difference meter. Additionally, tensile strength, absorbance using methylene blue, and gloss were measured to examine changes in the characteristics of hair texture.
Results : The results indicated no changes in the L* value for healthy hair, whereas hair-dyeing effects were observed for 7L(2), 7L(3), and 9L(3). Analysis of a* and b* values revealed that healthy hair remained the same, whereas significant hair-dyeing effects were noted for 7L(1), 7L(2), 7L(3), and 9L(3). In terms of fading, the most notable fading occurred on Day 1, whereas none was noted on Day 3. Samples 7L(1), 7L(2), 7L(3), and 9L(3) were used to test for tensile strength, where no changes in hair texture were observed. Furthermore, analysis was conducted on healthy hair and samples 7L(1), 7L(2), 7L(3), and 9L(3) after measuring absorbance using methylene blue. No changes in hair texture were noted. Lastly, the hair samples exhibited no changes after measuring gloss.
Conclusions : The study confirmed the hair-dyeing effects of the Arecae Semen pigment. According to hair texture, changes were observed for gloss, whereas tensile strength and absorbance remained the same. In the future, conducting the study on larger samples is necessary to ensure the reliability of results and research on various methods of hair dyeing.
