Each application lasts until you shampoo. Each DermMatch container (one disc) lasts, on average, eight months. Eight months is the average reorder time among DermMatch customers. All hair loss concealers will use-up more quickly if you are covering a larger area and using them more often. Hair fibers, sprays and other hair loss concealers don’t last nearly as long as DermMatch. They are filled with air and propellant and they will cost you much more to use.
