tiny keratin particles that thicken and conceal thinning hair
Keratin fibers, also known as hair building fibers or hair thickening fibers, are tiny, hair-like particles made from the protein keratin, which is the same protein that human hair is composed of. These fibers are used to conceal thinning areas on the scalp by clinging to existing hair through static electricity, creating the appearance of fuller, thicker hair. They are a popular cosmetic solution for individuals experiencing hair loss or thinning.
