cosmetic product that temporarily makes hair appear thicker

Do hair fibers wash out easily, or do you need a special shampoo to remove them? There is no published trial comparing shampoos for removing hair fibers. Because the fibers cling by static rather than bonding chemically, and because users consistently report they rinse out with ordinary shampoo, the specialist fiber-removal shampoos do not appear to be necessary; a clarifying shampoo may help when fibers are layered under hairspray or gel.
Do hair fibers really make thinning hair look fuller, or is it just an illusion? Hair fibers create an optical illusion of fullness but do not actually thicken hair.
How do you apply hair fibers correctly so they stay in place all day? Apply hair fibers to clean, dry hair and use a setting spray for better hold.
