Abstract |
We have found that higher low-molecular-weight protein concentrations earthworms as peptide can be obtained when the earthworms are ground, autolyzed for 24 hours, and then centrifuged compared to when the earthworms are centrifuged first and then autolyzed. Here, the optimum temperature for autolysis is 60oC. We used the earthworm virgin hair as a pre-treatment for one group. Compared to the control group, this pre-treatment group showed 16% shorter curl formation on natural hair and 12% shorter curl formation after 30 times of shampooing, indicating better curl formation and longer-lasting curl. The hair of the pre-treatment group was 3.4% thicker than that of the control group, the tensile strength 37.0% higher (p<0.001), the absorbance 64.2% lower (p<0.001) according to the Methylene Blue Method, the attachment of the scales on the hair much stronger (observed by SEM), and almost no peeling off. Hence, the experiment shows that the pre-treatment with earthworm autolyzate, obtained at 60oC, helps to increase curl formation and achieve long-lasting curl even on natural hair, and reduce hair damage. Therefore, it is possible to use earthworm autolyzate as an ingredient for hair care products. |
