This study aimed to investigate the antioxidant activity of Chenopodium quinoa extract and its effects on improving bleached hair when used in hair treatments. To achieve this, the antioxidant activity of Chenopodium quinoa extracts obtained at 40°C and 70°C was evaluated by measuring total polyphenol content, total flavonoid content, and Ferric Reducing Antioxidant Power (FRAP). Subsequently, hair treatments containing Chenopodium quinoa extract at different concentrations (No addition 0%, 3%, 5%, 7%, and 10%) were formulated and applied to bleached, damaged hair. The effects were assessed through tensile strength measurements, hair thickness analysis using SEM (interrupted), hair surface observation, and hair roughness analysis using Confocal Microscopy. The results, Chenopodium quinoa extract exhibited superior antioxidant activity, particularly in low-temperature extracts. Additionally, as the concentration of low-temperature Chenopodium quinoa extract increased, tensile strength and hair thickness improved, the damaged cuticle surface became smoother, and hair roughness was reduced. These findings confirm that Chenopodium quinoa extract is a safe and effective natural ingredient for hair cosmetics, highlighting its potential application as a natural hair care material.

본 연구는 퀴노아 추출물의 항산화 활성과 헤어 트리트먼트의 탈색모 개선 효과를 알아보고자 하였다. 이 를 위해 40℃와 70℃에서 침출한 퀴노아 추출물의 항산화 활성(총 Polyphenol 및 총 flavonoids 함량, FRAP)을 측정하였다. 이후 농도별(No addition 0%, 3%, 5%, 7%, 10%) 퀴노아 추출물을 첨가한 헤어 트리트먼트를 제조 하여 탈색 손상 모발에 도포하고 인장강도, SEM 이용한 모발 굵기(중단) 측정과 모발 표면 관찰, CONFOCAL을 이용한 모발 거칠기 측정을 하였다. 그 결과, 퀴노아 추출물은 특히 저온 추출물에서 우수한 항산화 효과를 확인 하였다. 또한 인장강도, 모발의 굵기는 저온 퀴노아 추출물 첨가량이 높아질수록 증가하였고, 손상된 큐티클 표면 은 매끄러워졌으며, 모발 거칠기가 개선되었다. 따라서 퀴노아 추출물은 인체에 안전하고 효과적인 모발 화장품 천연 소재로서의 활용 가능성이 검증되었다.
