The physical properties of damaged hair such as break point and extention were studied in relation to Cu-uptake onto hair.It was found that;(1) A good relationship existed between Cu-uptake and degree of damage in a bleached or in a cold waved hair. The Cu-uptake onto hair increased with the increase of the degree of damage. It may be possible to evaluate the degree of damage in hair by Cu-uptake as a parameter.(2) There was a good relationship between Cu-uptake and the break point or the extention of damaged hair. With the increase of Cu-uptake onto hair, the break point of damaged hair decreased, while the extention of damaged hair increased. These physical properties of damaged hair did not depend on a chemical treatment.(3) The break point of damaged hair had the maximum point at the range of pH 4 to 6, which seems to be related to the isoelectric point of keratin fiber.
