  • More hair fibers have a long list of ingredients, but Dr. Sam Lam's hair fibers have only two ngredients: natural plant fiber and a natural colorant, making them far less toxic to the hair and scalp and more appealing to people with sensitive skin. In contrast, most popular options like Toppik are full of toxic chemicals. Dr. Lam's fibers are available in 9 shades to suit everyone.
