Algin is extracted from brown seaweed freshly harvested from the sea or foraged from beaches. Seaweed is one of the oldest plant organisms in the world. These plants are known for their high vitamin and mineral content. Once the seaweed is collected, it is cleaned, dried and ground. The algin is then extracted in an additional process.
It is actually a byproduct of iodine extraction. Algin is a salt that is mostly used as a natural gelling agent. This traces back to its original role as a survivor in the ocean: it can bind water. It is used as a gelling agent in all of our plant-based hair dyes. Algin creates a creamy, non-drip paste that is easy to apply to hair.
