"Toppik Hair Building Fibers ($47) gives the instant appearance of a thick, full head of hair. These fibers are made from natural keratin of the highest grade (the same type of protein found in real hair). They have a strong natural static charge that creates a magnetic effect, tightly binding the building fibers to even the finest strands of human hair. The results have changed the lives of millions of women and men, from those struggling with fine or thinning hair to those with alopecia or undergoing chemotherapy." — Deycke Heidorn, hairstylist
