title: [Physico-chemical properties of head hair of people of European and Negroid races].
abstract: Comparative studies of head hair obtained from europeoid and negroid people showed no difference in water and sulfur content, resistance to temperature exposure and alkaline solution as well as in electrophoretic distribution of keratin proteins. At the same time values of rupture loads and extension as well as value of curl elasticity of negroid people's hair surpass substantially the same characteristics of europeoid people's hair.
