头发拉伸损伤模型的建立与护发成分修护效果的研究

用定性（SEM）与定量（折断功）方法，建立了头发拉伸损伤的模型：在50％相对湿度下，用Diastron仪以10％的拉伸量，拉伸头发150次，并以此模型研究了分别含护因子C和角蛋白的护发液对拉伸头发的修护作用。结果表明，护发因子C修护伤头发效果比角蛋白修护头发效果明显。

Model of Hair Extension Damage and Restoration of Damaged Hair by Conditioners

By qualitative(Scanning electron microscory)and quantification(work to break hair)assessments,the model of hair extension damage was established;the hair stresses were treated to 150 strain cycles under a constant level at 10 % extension in the lab of 50 % RH.With this model,the effects of protective factor C and keratin on hair damaged by extension were studied.The results showed that effciency of restoration of testing lotion contained protective factor C on damaged hair is higher than that of keratin.
