毛髪のパーマネントウェーブ形成におよぼす前処理の効果

摘要

毛髪は，毛髪の最外層にうろこ状に並んでいるキューティクル細胞，毛髪内部の大部分を占める紡錘状のコルテックス細胞で構成されている．これらの細胞は，細胞膜複合体（Cell Membrane Complex；CMC）と呼ばれる細胞組織により接着されている．また，キューティクル細胞間に存在するCMCと，コルテックス細胞層で網目状の模様を形成して存在するCMCは組織の構成が異なることが報告されている［1］．%The effect of the modification of human hair components on the permanent wave set of a human hair was investigated by analyzing the wave performance for both normal hairs and pretreatment hairs. Pretreatments carried out by treating the normal hairs with formic acid and acetic acid, ethanol/ chloroform, and boiling water. The difference between the protein chain rearrangements to equilibrium the curled configuration of normal and pretreatment hairs were observed during drying of the waved hairs. Specifically, the hair samplers pretreated with formic acid and acetic acid or ethanol/chloroform have made it difficult to maintain the waving performance in wet state. These results suggest that the constituent components of CMC play an important role to equilibrium the curled configuration by effectively operating as an adhesion component between the cells. A role of the constituent components of CMC for bleached hairs is also discussed.
