The invention relates to the technical field of
cosmetics, in particular to polypeptide essence with an anti-alopecia function and a preparation method of the polypeptide essence. The polypeptide composite component is formed by mixing acetyl
tetrapeptide-3 and
oligopeptide-54 according to the
mass ratio of 1: (1-3). The acetyl
tetrapeptide-3 can activate fibroblasts, promote synthesis of
laminin, III type collagen and VII type collagen, reinforce an epidermis-
dermis connecting structure, reduce the
hair loss rate and prolong the
hair growth period; the
oligopeptide-54 can lower
hair loss related
signal molecules such as DKK-1, stimulate
hair follicle activity, promote melanogenesis and improve the problem of
premature graying of hair. The combination of the two can synergistically improve the anti-
hair loss effect from different action targets, experiments prove that the polypeptide activity in the proportion range is the highest, the excessive addition easily causes component agglomeration and reduces
bioavailability, and the expected effect cannot be achieved if the addition is insufficient. The invention has the beneficial effect of high-efficiency hair loss prevention: the polypeptide and the
plant extract have a synergistic effect, and the problem of hair loss is solved from multiple dimensions of activating hair follicles, strengthening hair anchoring and improving
scalp environment.
