Abstract:
A hair-penetrating shield  220  comprises a tooth array having top  280  and bottom  290  surfaces. In some embodiments, for a majority of the teeth, a cross section of each tooth (for example, triangular in shape) has an asymmetric width profile such that the tooth cross section, on average, is narrower near the top of the tooth and wider near the bottom of the tooth. In some embodiments, a ratio between: i) a first average tooth width describing the average tooth width below the top-bottom midpoint; and ii) a second average tooth width describing the average tooth width above the top-bottom midpoint is at least 1.2, or at least 1.6. In some embodiments, a non-viscous hair-coloring agent is dispensed as a mist over the top of the surface of the shield so as to color roots of hair passing through the spaces between the teeth of the user's hair. In some embodiments, closely-spaced teeth of the hair penetrating shield protect the user's scalp from the non-viscous hair-coloring agent. Related methods and kits are disclosed herein.

Claim (Index 33):
A hair-coloring device for coloring hair roots, the device comprising:\n a) a hair-penetrating shield having top and bottom surfaces, comprising a slot array having at least eight elongated shield-thickness-spanning narrow slots that are substantially aligned a proximal-distal direction, the hair-penetrating shield including a longitudinal section of at least 2.5 cm where:\n i) for a majority of slots of the array, each slot provide a shield-thickness-spanning property throughout a majority of the longitudinal section; \n ii) an array-wide average cross-section-minimum-slot width is between 0.3 mm and 1 mm and/or for the majority of slots of the array each provide, throughout a majority of the longitudinal-subsection cross-section-minimum-slot width that is between 0.3 mm and 1 mm; \n iii) for the majority of slots of the slot array, a slot aspect ratio within the longitudinal section is at least 30, the slot aspect ratio being defined by a ratio between the slot length within the section and an individual-slot longitudinal-averaged cross-section-minimum-slot width averaged over the longitudinal section; \n iv) an array-wide average slot-slot lateral distance within the longitudinal section is at most 3 mm and/or at most a value equal to 3 times the array-wide average cross-section-minimum-slot width within the longitudinal section \n the hair-penetrating shield including a plurality of elongated, tapered penetrating elements located at the distal end of the shield; and; \n b) an aerosol assembly coupled to the hair-penetrating shield, the aerosol assembly including an aerosol outlet elevated above the top surface of the shield, the aerosol assembly configured to dispense a non-viscous hair-coloring agent as a mist in a proximal-distal direction defined by the array of teeth onto the top surface of the shield such that the hair-penetrating shield protects the space beneath the bottom surface from the non-viscous hair-coloring agent.
