Hair building fibers are fine powder particles. They are applied to hair so they can cling to existing strands and make the hair look fuller. Many fiber products rely on a static charge to help the powder stick. The brand says its fibers are charged so they spread evenly and do not clump. Results depend on your hair, the shade you choose, and how the powder is applied. Read the full ingredient list and check the shade before using any fiber product.
