Abstract: An improved applicator for hair building cosmetic fibers, powders and particles uses a gentle stream of gas to suspend the fibers and waft them onto the user's scalp. A low pressure, low velocity gas stream directed downwards into a mass of fibers in a closed container suspends them. The suspended fibers exit through a small orifice connected with a passageway ending in a nozzle. The suspended fibers are propelled from the nozzle in a directed fashion to settle naturally in a controlled area. If a rubber bulb is used to supply air to suspend the fibers, a user can gently squeeze the bulb to allow controlled puffs of air and fibers to waft onto controlled regions of the scalp. A valve arrangement can be operated to provide an air stream to remove excess deposited fibers from regions of the scalp.
