There are two ways to use conditioner:

One way is to wash your hair after shampooing, take a proper amount of conditioner, rub your hair for a while, and then rinse it with water.

Another method is to rinse the washed hair, take a proper amount of conditioner and disperse it in a basin filled with clear water, then rub it with the dispersed conditioner for a while, and then rinse it with clear water.
