头发的好坏不仅影响人的外观,同时还是自身活力的一种体现。因此人们现在对头发的护理越来越“挑剔”。 从化学角度上讲,人的头发几乎全部由角朊组成。角朊是一种蛋白质,不溶于酸和碱,并且耐酶的分解,因此头发的自身保护能力是很强的。 现代美发科学把护发分为表层初级护理和内部深入护理两步。在护发用品的选用上也应强调配套使用系列产品。
The quality of the hair affects not only the appearance of the person, but also an expression of one’s own vitality. So people are getting “critical” about hair care nowadays. From a chemical point of view, almost all of human hair consists of keratin. Keratin is a protein that is insoluble in acids and bases, and is resistant to enzymatic decomposition, so the hair’s own protective ability is very strong. Modern hair science hair care is divided into surface primary care and internal care in two steps. In the selection of hair care products should also emphasize supporting the use of products.
