Human hair is a natural fiber with keratin and keratin-related proteins as a main component. Externally, hair is a thin, pliable tube of dead, fully keratinized epithelial cells, while inside the skin, it is part of a single living hair follicle. In addition to a large amount of protein, hair also contains low levels of lipids and pigments. The hair also has its own ecological balance system. Although the lipid content in hair is much lower than the protein content, it plays an important role in hair and influences hair texture to some extent. For example, prevent hair breakage and thinning; To act as a barrier to moisture loss; and improve the gloss, elasticity and tensile strength of the hair stem. Environment, hair dressing and daily care can all cause hair damage to varying degrees. Factors such as ultraviolet light and chemicals can make hair dry, rough, dull, stiff and brittle by destroying the proteins, pigment sand lipid sin the hair. In this paper, the composition, classification and influencing factors of hair were reviewed. The composition and function of lipids in hair were investigated emphatically. It aims to improve people's understanding of the physical and chemical properties and structure of hair. It provides reference value for the research and development of hair cosmetics for different hair states and washing purposes. The function of hair lipids on hair is not accurate. In addition, there is still some controversy on the existing role of hair lipids, which needs further research.

모발은 케라틴과 케라틴 관련 단백질을 주성분으로 하는 천연 섬유이다. 외부에서 모발은 완전히 각질화된 죽은 상피 세포로 이루 어진 얇고 유연한 관이지만, 피부 내부에서는 살아있는 모낭의 일부로 구성되어 있다. 모발에는 다량의 단백질 외에도 낮은 수준의 지질과 색소가 포함되어 있다. 그 외에도 모발에는 고유한 생태학적 균형 시스템이 있다. 모발의 지질 함량은 단백질 함량에 비해 훨씬 낮지만 모발에 중요한 역할을 하며 모발의 질감에도 어느 정도 영향을 미친다. 예를 들어, 모발의 파손과 숱이 줄어드는 것을 방지하고, 수분 손실을 막는 장벽 역할을 하며, 모발의 윤기와 탄력, 인장강도를 향상시킨다. 환경, 미용, 일상적인 관리 등은 모두 다양한 정도의 모발 손상을 유발할 수 있다. 자외선 및 화학 물질과 같은 요인은 모발의 단백질, 색소, 지질을 파괴하여 모발을 건조 하고, 거칠고, 둔하고, 뻣뻣하고 부서지기 쉽게 만들 수 있다. 본 총설에서는 모발의 구성, 분류, 영향요인에 대해 종합적으로 고찰 하였고, 특히 모발 내 지질의 구성과 기능을 집중적으로 고찰하였다. 본 총설은 모발의 물리적, 화학적 특성과 구조에 대한 사람들 의 이해를 높이는 것을 목표로 하여, 다양한 모발 상태와 세척 목적에 따른 모발 화장품 연구 개발에 기초적인 가치를 제공하고자 한다. 모발에 대한 모발 지질의 기능은 명확하지 않으며, 모발 지질의 기존 역할에 대해서 여전히 논란이 있어 추가 연구가 필요하 다고 사료된다.

头发是一种天然纤维，以角蛋白和角蛋白相关蛋白为主要成分。从外部看，头发是由死亡的、完全角化的上皮 细胞组成的薄而柔韧的管状物，而在皮肤内部，它是单个活毛囊的一部分。头发内除了含有大量的蛋白质外， 还含有低水平的脂质和色素。除此之外，头发上有着自己的生态平衡体系。尽管头发中脂质的含量远低于蛋白 质含量，但其在头发中扮演着重要的角色，对头发质地有一定程度的影响。例如，防止头发断裂和变薄；用作 水分损失的屏障；并改善发干的光泽度、弹性和拉伸强度等。环境、美发及日常护理等均会不同程度地造成头 发的损伤。例如紫外线、化学剂等因素，通过破坏头发的蛋白质、色素和脂质等，使头发变得干燥、粗糙、无 光泽、僵硬和易脆。本文对头发的物质组成、分类概况及影响因素进行综述。着重调查了头发中脂质的成分及 其作用。旨在提高人们对头发理化性质和结构的了解。为不同头发状态和洗涤目的的头发化妆品的研发提供参 考价值。 头发脂质对头发的功能作用并不精确，此外，对头发脂质已有的作用仍存在一定的争议，需要进一步 研究。
