香烟烟雾为模型的污染环境对头发损伤的研究

基于香烟烟雾建立了模拟空气污染的环境,测试健康和受损发束在该污染环境中的损伤情况。通过对比多次处理前后暴露污染的样品发束和未暴露污染的对照发束的湿发和干发梳理性、表面接触角、色氨酸含量和表面毛鳞片特征的变化,表明该污染环境对头发有显著的化学损伤。尤其是健康头发暴露空气污染后表面毛鳞片受损和角蛋白损伤降解,表面更加亲水,梳理性变差。通过以上方法在健康发束上证明了聚合物聚酰亚胺-1具备抵御损伤的能力。

Study on hair damage caused by polluted air environment simulated with cigarette smoke

Polluted air environment was established based upon a simulating chest that filled with cigarette smoke. Bundles of healthy virgin hair and hair that exposed many times in the cigarette smoke were tested and performance compared, including carding of dry hair and wet hair, surface contact angle, tryptophan level and surface cuticle morphology. Results show that the exposure in cigarette smoke results in significant chemical damage of the hair. Especially, after exposure in the polluted environment, the hair cuticle of the healthy hair is damaged, and its keratin is degraded, which causes the hair fibers becoming more hydrophilic and tangling for carding. This method has been applied to prove that the polymer polyimide-1 can be used for protecting hair damage caused by polluted air.
