Solid Shampoo Bar
Shampoo in solid form, also called soap bar, is a more environmentally friendly and sustainable alternative to liquid shampoo. It is compressed into a solid block that looks like a bar of soap, and is often packaged minimally or not at all in plastic. Soap bars are known for their lower environmental impact as they require less packaging and have a longer shelf life. They are also easy to transport and ideal for travel. To use a bar of soap, simply wet it and lather it in your hands or directly into your hair before massaging it into your hair like traditional shampoo.
