Study on the Effect of Hair Toner Formulated with Rubus Occidentalis L. Extract on the Hair Damaged by Bleaching

This investigates the effect of hair toner formulated with Rubus Occidentalis L. extract on hair damaged by bleaching. The antioxidant functions of bokbunja material was examined via the tests of total phenol content, flavonoid content, and Vitamin B analysis. Bokbunja hair toner was prepared in 3 different concentrations. Untreated hair tress was bleached using a commercial hair bleaching agent and then treated with <shampoo→towel dry→air dry→toner treatment> once each day for 40 days. Hair samples were examined on their surface characteristics, tensile strength, and amount of protein leak. Total phenol content of the bokbunja material was 2999.50 μg GAE/mL and the flavonoid content was 955.140 μg CE/mL. Vitamin B contents were B2 0.403 μg/mL, B3 0.545 μg/mL, B5 0.357 μg/mL, B6 0.213 μg/mL, and B7 0.022 μg/mL. Tensile strengths of bleached hair without bokbunja hair toner treatment were 368.3 MPa, 386.2 MPa, and 479.4 MPa which were only 43.1～56.1% of the tensile strength of untreated hair. Bleached hair increased in tensile strength to 488.8 MPa, 549.2 MPa, and 521.6 MPa after 40 days of toner treatment. Bleached hair showed a higher amount of protein leak (218.48 μg/mL) compared to untreated hair (186.53 μg/mL). After 40 days of bokbunja hair toner treatment, the protein leak of hair treated with 3 different toners was 247.57 μg/mL (5%), 241.22 μg/mL (10%), and 267.13 μg/mL (15%) which were significantly higher than the protein leak of untreated hair as well as the protein leak of bleached hair without the toner treatment.
