Moisten the bar with some water then apply bar directly from mid lengths to ends of hair using a rubbing motion. Gently massage the lather into hair and comb through then rinse out thoroughly. Leave bar out to air dry, ready for its next use.
To get the most out of your bar and ensure it goes the distance, never let it soak in water and allow the bar to air-dry after each use. Do not let it sit in puddles of water in your shower otherwise it can turn into a soggy mess and you'll find you'll need to replace it sooner that expected.
