Hair keratin film as a substitute device for human hair

Application in hair care science

抄録

Keratin film prepared from human hair samples can be considered a model which represents an average human hair. In this study, the investigations were focused on whether the keratin film can withstand physical and chemical stimulations such as ultraviolet (UV), bleach, perm, and thermal treatments or not. Obtained data indicated that keratin film responded to such hair damage factors in the similar manner as hair, and responses of keratin film were significantly higher than those of hair. Keratin film can be used as a substitute device for human hair, to accurately evaluate hair damage for the development of hair care related products.
