Abstract: A dispenser for hair building solids can be readily operated and aimed with one hand. A bulb that provides air for suspending the solids is located directly on top of a dispenser body. The bulb can be depressed by a single finger when the device is held in one hand. When the compressed air exits the bulb, it follows a direct straight downward pathway to the surface of the hair building solids. Air exiting the bulb passes through an air injecting orifice that is directed towards the surface of a mass of hair building solids suspending the solids within the turbulently pressurized container, which solids are then directed smoothly by the domed undersurface of the dispenser body into the straight bore of a short nozzle. The path followed by the solids is without bends thereby avoiding clogging.

Abstract: A handled laser treatment device provides a plurality of branched light pipes or light distribution tips distributed so as to evenly deliver laser radiation to the surface of the scalp. To make efficient use of each laser diode, each laser can coupled to a branched light pipe with the branches arranged to distribute light directly to the surface of the scalp. Each laser source is connected to a three branch light pipe. Alternatively, each laser diode can be directly coupled to a light distribution tip arranged in a triad. Each light pipe or light distribution tip acts as a tine or tooth in a comb to bring laser radiation to the scalp free of obstruction by hair, etc., with a tripod configuration that allows each light pipe assembly to evenly contact the rounded surface of the scalp.

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.
