A hair treatment process comprises the following steps A or B, and includes conducting shaping of hair in at least one of the steps:
Steps A: A first pack with a reducing agent contained therein and a second pack with an oxidizing agent contained therein, said second pack having buffer capacity and a pH of from 1 to 5, are successively applied to the hair, and the hair is rinsed with water and is dried (the first pack or the second pack contains an organic acid (A) or a salt thereof),
Steps B: A first pack with a reducing agent contained therein, an intermediate treatment having buffer capacity and a pH of from 1 to 5, and a second pack with an oxidizing agent contained therein are successively applied to the hair, and the hair is rinsed with water and is dried (the first pack or the intermediate treatment contains the organic acid (A) or salt thereof),
Organic acid (A): a compound comprising a non-aromatic hydrophobic group having a total carbon number of from 3 to 11 or an aromatic hydrophobic group having a total carbon number of from 4 to 18 and an acidic group such as a sulfo group, sulfate ester group or the like.
By a procedure as simple as conventional straight perm, an extremely high, extremely curly hair correcting effect can be obtained. Further, subsequent to the treatment, the corrected state can be restored or maintained by a routine aftercare without damaging the hair.
一种头发处理工艺包括以下步骤 A 或 B,并包括在其中至少一个步骤中对头发进行塑形:
步骤 A:将含有还原剂的第一药包和含有氧化剂的第二药包(所述第二药包具有缓冲能力,pH 值为 1 至 5)依次涂抹在头发上,然后用水冲洗头发并烘干(第一药包或第二药包含有一种有机酸(A)或其盐)、
步骤 B:将含有还原剂的第一包装、具有缓冲能力且 pH 值在 1-5 之间的中间处理剂和含有氧化剂的第二包装依次涂抹在头发上,然后用水冲洗头发并烘干(第一包装或中间处理剂含有有机酸(A)或其盐)、
有机酸 (A):一种化合物,包含一个总碳原子数为 3 至 11 的非芳香族疏水基团或一个总碳原子数为 4 至 18 的芳香族疏水基团和一个酸性基团,如磺基、硫酸酯基或类似基团。
通过与传统直发烫发一样简单的程序,就能获得极高的极卷发矫正效果。此外,在治疗之后,还可以通过常规的后期护理来恢复或保持修正后的状态,而不会损伤头发。
