Bar shampoo works by being activated with water, allowing you to create a lather and cleanse your hair. Think of it as a concentrated soap bar specifically formulated for hair.
Here's a breakdown:
- Activation with Water: The shampoo bar is a solid form of concentrated shampoo ingredients. Water is needed to dissolve a small amount of the bar's surface.
- Creating Lather: Once wet, you can create a lather by rubbing the bar directly onto your wet hair or by rubbing the bar between your wet hands and then applying the lather to your hair. The lather isn't usually as abundant as with liquid shampoos, but it's typically rich and creamy.
- Cleansing Action: The lather, produced by the interaction of water and the bar's ingredients (typically surfactants and oils), works to lift dirt, oil, and buildup from your hair and scalp.
- Rinsing: After massaging the lather into your hair and scalp, thoroughly rinse with water to remove the shampoo and the loosened debris.
In short, a shampoo bar acts as a solid concentrate that, when combined with water and agitation (rubbing), creates a cleansing lather.
