A hair protection film of the present invention aims at preventing and curing damage to the hair due to cold permanent wave treatment. The hair protection film for cold permanent wave treatment has a "sandwich" or three layer structure with a center layer coated on both sides with a protective layer. The center layer is formed of a film or a thin layer consisting mainly of at least one of "water-soluble natural sugar", "blood plasma", and "substitute blood plasma", or of a film or a thin film obtained by dispersing an extract of corn grains or a concentrate of brewage in polyvinyl alcohol. The protective layer that coats both surfaces is one of an alkali-soluble coating layer, an acid-soluble coating layer and a heat-soluble coating layer.
