First, let’s clarify exactly what a loofah is: it does not come from the sea. Loofah is a vegetable in the gourd family. The squash is picked, dried, and skinned.
What remains is what you see below and in bathtubs around the world. It’s even believed to have been used by Egyptians! You can cut the full loofah plant into pieces based on your specific needs or purchase already cut.
