How to use Shampoo Soap
You use shampoo soap just like you would shampoo. The bar is rounded so it fits neatly into your hand. Wet your hair, give it a couple of swipes, and your hair will be filled with a bubbly lather.
By switching to shampoo soap, you are lowering the carbon footprint of your hair care routine—no plastic packaging or water fillers to pay for and transport.
