Abstract

Modern people express their beauty through hair coloring, but hair can be damaged by repeated chemical treatments. In order to increase the durability of dyeing and minimize the hair damage, in this study, the acidic amino acids including aspartic acid (Asp) and glutamic acid (Glu) were used to post-treat hair during hair coloring. The post-treatment with 0.75% Asp and Glu solution was carried out at room temperature for 20 minutes after dyeing bleached hair with cherry red and blue silver colors. After repeated shampooing of 1, 5, 10, 15, 20, and 25 times, L*a*b* value of dyed hair was measured to confirm the dyeing durability, and the changes in tensile strength, porosity, and surface properties of the hair were also analyzed to determine the condition of the hair. In the case of cherry red and blue silver staining, the Asp and Glu experimental group showed higher color persistence than the control group, and the Asp and Glu experimental group showed higher tensile strength, lower porosity and smooth surface properties than the control group. In particular, the Asp test group showed superior color persistence and lower hair damage than the Glu test group. This study, therefore, if damaged in dyeing and bleaching in the field of hair after treatment with asp glu a combination of hair cosmetics in the development of basic data look forward to be.

현대인들은 헤어컬러링을 통하여 아름다움을 표출하는데 반복적인 화학적 시술에 의하여 모발은 손상을 받는다. 염색의 지속력을 높이고 모발 손상을 최소화하기 위해 본 연구에서는 헤어컬러링 시 산성 아미노산인 아스파트산(Asp)과 글루탐산(Glu)으로 모발을 후처리하였다. 탈색모에 체리레드와 블루실버 색상으로 염색하고 0.75%의 Asp와 Glu 용액을 실온에서 20분간 후처리를 한 후 1회, 5회, 10회, 15회, 20회, 25회 샴푸 후 L*a*b*값을 측정하여 염색 지속력을 확인하였고, 모발의 상태를 알아보기 위하여 모발의 인장강도, 기공도, 표면 특성의 변화를 분석하였다. 체리레드와 블루실버 염색을 진행한 경우 모두 Asp와 Glu 실험군이 대조군 보다 높은 색 지속력을 보였고 Asp와 Glu 실험군은 대조군보다 높은 인장강도, 낮은 기공도, 매끄러운 표면특성을 나타냈다. 특히 Asp 실험군이 Glu 실험군 보다는 우수한 색 지속력과 낮은 모발 손상도를 나타냈다. 따라서 본 연구가 현장에서 탈색과 염색 시 손상된 모발의 후 처리제로 Asp와 Glu을 조합한 모발 화장품 개발의 기초자료가 되기를 기대해 본다.
