Frequently Asked Questions
Toppik Hair Building Fibers are made from keratin, the same protein found naturally in human hair. The formula is derived from plant-based sources and uses static electricity to bond with existing hair strands. The Perfecting Duo includes both the fibers and a specialized applicator spray for even distribution. The ingredients are hypoallergenic and free from harmful chemicals, making them safe for daily use on all hair types.
Yes, Toppik Hair Building Fibers are hypoallergenic and dermatologist-tested, making them suitable for sensitive scalps. The keratin-based formula doesn't clog pores or cause irritation for most users. However, if you have a known allergy to keratin or plant proteins, we recommend performing a patch test first. The fibers sit on the hair shaft rather than the scalp, minimizing direct contact with sensitive skin.
Toppik fibers typically last throughout the day until you wash your hair. The static-bonded fibers remain in place during normal daily activities, including gentle brushing and light perspiration. For maximum longevity, apply the included applicator spray after using the fibers—this helps set them and can extend wear time. The effect is completely washable with regular shampoo, making it a temporary yet reliable solution.
