Hair coloring is broadly used by women and men either to change their natural hair color or to delay the onset of gray hair. Oxidative dyes may damage the hair, as chemical and physical processes are required to convert the fiber structure and, consequently, alterations in its mechanical and surface properties.
The aim of this study was to evaluate the protective effect of silanetriol (and) Panthenol, PEG-12 dimethicone, and hydrolyzed silk (and) hydrolyzed milk protein (and) lactose as conditioner agents on hair treated with oxidative hair dye by protein loss, combability, and breaking strength.
In this research, we analyzed the untreated hair (sample I) and the effect of oxidative hair dye emulsions, with or without conditioner agents (sample II) silanetriol (and) Panthenol (sample III), PEG-12 dimethicone (sample IV), and hydrolyzed silk (and) hydrolyzed milk protein (and) lactose (sample V) on Caucasian hair. The hair samples were submitted to protein loss quantification, breaking strength, and combing analysis.
For protein loss, the results were: II = V > IV > III > I . For the breaking strength: I = II = III = IV = V . For the combing analysis for wet and dry hair, the results were, respectively: II > III = IV > V > I and II > III = V > IV = I . Data classified by different letters presented statistically significant alterations, α = 5, P ≤ . 05, n = 15.
Based on these results, the incorporation of conditioner agents into emulsion blond color decreased the damage caused by the coloring process.
无论男女，染发都被广泛用于改变自然发色或延缓白发的出现。氧化型染发剂可能会损伤头发，因为需要通过化学和物理过程来改变纤维结构，从而导致其机械性能和表面性能发生改变。
本研究旨在通过蛋白质损失、梳理性能和断裂强度，评估硅三醇（和）泛醇、聚乙二醇 -12 二甲基硅氧烷、水解丝蛋白（和）水解乳蛋白（和）乳糖作为调理剂对经氧化型染发剂处理的头发的保护作用。
在本研究中，我们分析了未经处理的头发（样品 I）以及氧化型染发剂乳液（含或不含调理剂）（样品 II）、硅三醇（和）泛醇（样品 III）、聚乙二醇 -12 二甲基硅氧烷（样品 IV）、水解丝蛋白（和）水解乳蛋白（和）乳糖（样品 V）对高加索人头发的影响。对头发样本进行蛋白质损失定量、断裂强度和梳理分析。
蛋白质损失方面，结果为：II = V > IV > III > I。断裂强度方面：I = II = III = IV = V。干湿发梳理分析结果分别为：II > III = IV > V > I 和 II > III = V > IV = I。不同字母分类的数据呈现出统计学上的显著差异，α = 5，P ≤.05，n = 15。
基于这些结果，在乳液型金色染发剂中加入调理剂可减少染发过程造成的损伤。
