If stress, over-processing, or product build-up has your hair looking less than lustrous, go no further than the kitchen. Olive oil works wonders as an intensive conditioner, especially taming curly or frizzier hair types. Rich in fatty acids, olive oil penetrates the hair shaft to restore dry hair. Condition your hair with a dose of oil, covered by a heat cap, for shiny, healthier results. Olive oil works on your body too, transforming skin from dry to supple.
