The present invention relates to a hair treatment composition comprising a multi-arm polyethylene glycol derivative (A) containing two or more functional groups that may be covalently bound to amine, a hair treatment composition comprising a polyethylene glycol derivative (B), containing one or more functional groups that may react with the functional groups of said composition, and/or a biocompatible polymer (C), a hair treatment agent comprising these compositions and a method for using the same. The hair treatment agent of the present invention is capable of increasing the hair thickness and volume, restoring the damaged hair and lasting the hair shape and curls for a long time, by firstly covalently binding some functional groups of said polyethylene glycol derivative (A) to amino acids present on hair surfaces and then covalently binding some functional groups not covalently bound to hair, to a polyethylene glycol derivative (B) and/or a biocompatible polymer (C).
本发明涉及一种头发治疗组合物,该组合物包含一种多臂
聚乙二醇衍生物(A),其中含有两个或多个可与胺共价结合的官能团;一种头发治疗组合物,该组合物包含一种
聚乙二醇衍生物(B),其中含有一个或多个可与所述组合物的官能团反应的官能团,和/或一种
生物相容性聚合物(C);一种头发治疗剂,该头发治疗剂包含这些组合物,以及使用这些组合物的方法。本发明的头发治疗剂首先将所述
聚乙二醇衍生物(A)的一些官能团与存在于头发表面的
氨基酸共价结合,然后将一些未与头发共价结合的官能团与
聚乙二醇衍生物(B)和/或
生物相容性聚合物(C)共价结合,从而能够增加头发的厚度和发量,恢复受损的头发,并长期保持头发的形状和卷曲度。
