Moisten the bar with some water then apply bar directly from scalp to ends of hair using a rubbing motion, or alternatively rub between hands to create a generous lather. Gently massage the lather into scalp and hair, as you would with a liquid shampoo. Rinse out thoroughly and repeat the shampooing process once or twice for a deeper clean. Follow by applying conditioner to mid-lengths and ends of hair if some additional nourishment is required. Leave shampoo bar out to air dry, ready for its next use.
To get the most out of your shampoo bar and ensure it goes the distance, never let the bar 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.
