Amino Kera NPNF™ consists of highly hygroscopic free amino acids. Keratin is a highly specialized protective protein from in hair, feathers, wool and nails. With a high moisture binding ability and its small molecular size, Amino Kera NPNF™ can pull moisture to areas where it is most needed. Amino Kera NPNF™ is also a source of cysteine, an amino acid distinct to keratin and which provides strength to the hair by cross-linking covalently into disulfide bonds.

氨基卡拉NPNF™由高度吸湿的游离氨基酸组成。角蛋白是头发，羽毛，羊毛和指甲中高度专业化的保护性蛋白质。 Amino Kera NPNF™具有高水分结合能力和小分子量，可将水分吸引到好需要的地方。氨基芥子胺NPNF™也是半胱氨酸的来源，氨基酸不同于角蛋白，并通过共价交联成二硫键为头发提供强度。
