These hairs are made from nylon filaments of varying diameter. The hairs are to be pressed against the skin with enough force so that the hair buckles and forms a U-shape. Given that the force required for this is assumed to be constant, these hairs can be used to apply a very accurate force on specific areas of the skin, thus making von Frey hairs a possible diagnostic, research, and screening tool.
von Frey hairs are readily used to study skin areas with normal responsiveness, as well as hyper- or hyposensitive areas.
