tiny keratin-based strands used to conceal thinning hair
Hair fibers are tiny, keratin-based strands that are used to conceal thinning hair or bald spots. They adhere to existing hair through static electricity, creating the appearance of fuller, thicker hair. Popular brands like Toppik offer these fibers in various colors to match natural hair shades, making them a widely-used cosmetic solution for individuals experiencing hair loss or alopecia.
