Effects of Propolis Extracts on Damaged Hair

Purpose: This study aimed to investigate the effect of applying propolis extract to damaged hair.Methods: A matrix-improving formulation was prepared with the addition of 3, 6, and 9 g of propolis extract. The sample was applied to the formulation to which the extract was added, and damaged hair was measured and compared. To determine the effect on damaged hair, the study measured tensile strength, absorbance using methylene blue, and gloss.Results: The result indicated that average values increased for all samples applied with the formula. Specifically, the results statistically differed for samples 8(6) and 8(9) compared with those for damaged hair. Average values after absorbance measurement decreased for all samples with extracts with statistical results for samples 8(3), 8(6), and 8(9) compared with damaged hair. Lastly, average values for gloss measurement displayed increases for samples 8(3) and 8(6). The statistical results indicated no difference for all samples compared with those for damaged hair.Conclusion: The average values of the samples for tensile strength and absorbance indicated differences between damaged hair and propolis extract, which suggested that damaged hair was improved in terms of hair quality.
