Abstract: A method and composition treatment is used to reduce post permanent odor in permed or waved hair. The malodor in permed hair is reduced by applying a leave-in aqueous treatment of pH 2.5-4.5 containing, hydrolyzed vegetable protein, polyquaternium-7, dimethicone and fragrance containing at least four components with water/octanol partition coefficient Log Kow or log P of 3-4.5. The post permanent odor in hair is reduced by (1) minimizing any reactions of hair with residual chemical compounds in hair after the perming process or after the oxidation step and (2) lessen or suppress any odoriferous compounds by decreasing their vapor pressure and (3) depositing in hair long lasting fragrance components to mask or change the malodor to be more pleasant.
