Abstract

A hair processing apparatus has facing members for nipping hair. The facing members have uneven surface portions on their contact surfaces which are engaged with each other. The uneven surface portions have a plurality of grooves along their length directions. The hair is placed along the grooves between the facing members, and pressed by making the facing members closer. Simultaneously, the facing members are kept at a high temperature to heat the hair. A method for hair processing uses the apparatus.
