If you wat shiny hairtry washing it in cold water, it sounds weird but does work! You don't need it to be really cold but certainly not warm. This works best for short hair.
you can use a hair curler of if you have a hair straitner that has curved edges you can curl your hair with that :) i hope this is what you ment by without a product.
take good care of it by brushing, shampooing, conditioning and drying. I suggest if you really want your hair like that, use a good product of shampoo and conditioner and probably do it every day. You can also use hair product.
