Couldn't Be Easier: Package-Free Shampoo

I've recently become very fond of Lush, a shop that sells natural and eco-friendly bath and body products. Here are two of their package-free, solid shampoos, sold in bar-form. You merely lather one up, just like a regular bar of soap, and then shampoo your hair. It couldn't be easier. And there's no plastic bottle produced and then recycled.
Right now, I'm using New!, the red one, which boasts scalp-stimulating properties and a heady cinnamon fragrance. And recently, I received a free bar of Seanik, with my purchase. The dark flecks you see in it are pieces of seaweed.
