Founded in 2006, Toppik is a brand of haircare products that specializes in solutions for thinning hair and hair loss. Toppik haircare products include shampoos, conditioners, and treatments designed to nourish, strengthen, and thicken hair. The brand uses high-quality ingredients such as keratin, biotin, and collagen to help promote healthy hair growth and improve the overall appearance of thinning hair. One of Toppik's signature products is its "Hair Building Fibers," which are tiny, colored fibers that bond to existing hair strands to create the appearance of thicker, fuller hair. The fibers are made from natural keratin protein, the same protein that makes up human hair, and are available in a range of colors to match your natural hair color.
