The present invention provides a cosmetic composition or quasi-drug composition, comprising glycerin, shea butter, coconut oil, cyclopentasiloxane, and citric acid as effective components. In particular, the cosmetic composition or quasi-drug composition enables carboxymethyl cellulose (CMC), melanin, and acid amino acid components to penetrate the hair swollen during a treatment such as dyeing or perming； enhances peptide bonds so as to prevent loss of peptide fragments out of the hair； and neatens cuticles so as to prevent hair damage and diffuse reflection of a dye, thereby exhibiting an excellent effect of improving damaged hair.COPYRIGHT KIPO 2020본 발명은 글리세린, 쉐어버터, 코코넛오일, 시클로펜타실록산, 구연산을 유효성분으로 함유함으로써 염색 또는 펌 시술시 팽윤되어 있던 모발에 카복시메틸셀룰로스(carboxymethyl cellulose, CMC), 멜라닌, 산성 아미노산 성분을 침투시키고, 깨져있는 팹티드가 모발 밖으로 유실되지 않도록 펩티드 결합을 강화하고, 큐티클을 정리해줌으로써 모발의 손상을 막고 염색의 난반사를 막아주며, 손상된 모발을 개선하는 효과가 우수한 화장료 조성물 또는 의약외품 조성물을 제공한다.
