In general, it is hard to perm bleached hair. This study examined the effectiveness of permanent waves after dividing bleached hair into two groups: an experimental group (hair treated with 0.75% aspartic acid water), and a control group (hair treated with distilled water). In terms of wave retention when the hair was washed 30 times after receiving a perm, the experimental group was higher than the control group with 17.6% and 14.8% respectively. Retention was also affected by the number of times the hair was bleached. Hair bleached once exhibited better retention, 11.6% as compared to hair that had been bleach 3 times with 4.4%. In terms of tensile strength, the experimental group (6.04±0.16 kaf) was greater than the control group (5.31±0.14 kaf) by 13.75% (p<0.05) when the hair was bleached once. When bleached 3 times, the experimental group (4.60±0.16 kaf) was higher than the control group (4.27±0.22 kaf) by 7.73% (p<0.05). Regarding hair damage measured using the methylene blue method, the experimental group (0.208±0.016) was lower than the control group (0.262±0.020) by 20.61% in terms of absorption when bleached once (p<0.05). When bleached 3 times, the experimental group (0.375±0.028) was lower than the control group (0.473±0.038) by 20.72% (p<0.05). According to FE-SEM results, the experimental group was less than the control group in terms of cuticle damage when hair was bleached once as compared to hair that had been bleached 3 times. It could be used in the development of diverse hair care products.
