The Effect of Improving Demaged Hair by Bleaching Treatment with Adansonia digitata Seed Oil

Abstract

The purpose of this study is to examine the effect of <i>Adansonia digitata</i> seed oil on hair damaged by bleaching. Experimental materials were prepared by treating damaged hair that had been bleached 3 times in the following 4 ways. 1) Treatment base (T0), 2) 3% <i>Adansonia digitata</i> seed oil treatment (T3), 3) 7% <i>Adansonia digitata</i> seed oil treatment (T7), 4) 3% silicone oil treatment (S3). The effect analysis before and after treatment of bleached hair was carried out in the following way. First, to measure the damaged hair, that is, to measure the porosity, the hair to be damaged was placed in a methylene blue solution. Second, to test the dynamic properties of hair, tensile strength and yield strength were measured. Finally, to observe the changes in the morphological structure of the hair surface, electric field emission scanning electron microscopy (FE-SEM) images were employed. The absorbance measurement using methylene blue showed a decrease in the average in hairs dyed with 3% and 7% of <i>Adansonia digitata</i> seed oil, indicating that there was a hair improvement effect in hairs dyed with <i>Adansonia digitata</i> seed oil. As a result of studying whether the hair bleached containing <i>Adansonia digitata seed</i> oil has the effect of improving hair quality, the absorption strength decreased and the tensile strength increased. In addition, absorbance measurement, gloss measurement, and FE-SEM experiments were conducted. As a result, It was confirmed that there is an effect of improving hair quality in terms of the constant arrangement of cuticles on the hair surface and increasing the gloss of the hair. It was found that <i>Adansonia digitata</i> seed oil, a natural ingredient, has a high effect on improving hair quality of dyed hair in order to minimize damage to bleached hair. As a result of this research, it is expected that various products will be developed using <i>Adansonia digitata</i> seed oil.
