Abstract:
Embodiments of the present invention relate to a hairbrush for detangling human or animal hair. In some embodiments, the hairbrush includes a field of bristles where bristle height is substantially random and substantially independent of position on the hairbrush. In some embodiments, within the bristle field, the bristle width and/or the bristle material may vary between bristles - for example, substantially randomly with respect to position and/or in a manner that is correlated with bristle height.
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.
Abstract:
Hair-coloring applicators comprising a shield to protect the scalp, polymers of tannic acid having iron ions bound thereto, hair-coloring compositions comprising same and/or melanoidin, and novel alcohol-free carriers, are disclosed, as well uses thereof for coloring hair.
Abstract:
L'invention a notamment pour objet la gestion du câblage d'un cluster comprenant au moins deux armoires informatiques, chaque armoire informatique comprenant au moins un dispositif élémentaire, chaque dispositif élémentaire comprenant au moins un connecteur. Après avoir déterminé (240) au moins un lien logique externe entre au moins deux connecteurs dudit cluster, chacun desdits au moins deux connecteurs appartenant à une armoire informatique différente, et généré une liste d'interconnexions logiques comprenant ledit au moins un lien logique externe, des emplacements desdits au moins deux connecteurs sont identifiés. Un chemin de câble reliant lesdits au moins deux connecteurs est alors déterminé selon ladite liste d'interconnexions logiques et une liste d'interconnexions physiques comprenant au moins ledit chemin de câble est créée.
Abstract:
A method of selecting a substance for use in a cosmetic skin treatment comprises, measuring a reflectance spectrum of the skin to which said treatment is to be applied, said reflectance spectrum defining an original skin tone; modifying the measured reflectance spectrum in accordance with the absorbance spectrum of a substance proposed for said cosmetic skin treatment to provide a modified skin reflectance spectrum defining a modified skin tone; and matching such that if said modified skin tone appears to match said original skin tone then indicating said proposed substance in said cosmetic skin treatment, and otherwise repeating said modifying with a new proposed substance until a match is found.
Abstract:
An applicator (10) for spray application having a flat panel body (12) having a proximal end (14) and a distal end (16). The said proximal end (14) of the said flat panel body (12) is structured as a connector in a circular shape forming a rim (22) having an inner surface (24) and an outer surface (26), wherein, the said inner surface (24) of the said rim (22) functions as a connector to be fitted perfectly with the lid of a universal sprayer (28). Said applicatior enables the application of spray in a straight line rather than a circular or oval shape.
Abstract:
A naturally-derived emulsifier system for use in topically-applied dermatocosmetic products comprising (i) vegetal cholesterol derived semi-synthetically from a plant of the Dioscorea species ( D. composite, D. terpinapensis and/or D. villosa ) and/or Trillium erectum ; (ii) a botanically-derived phospholipid; and (iii) a botanical oil having a fatty acid content of at least 50% by weight of C 18 fatty acid(s) having at least two carbon- carbon double bonds.
Abstract:
A method to change the color of hair. The method includes measuring an initial reflectance spectrum of a sample of the hair and analyzing a contribution of a plurality of natural hair factors to the initial reflectance spectrum. The method also includes calculating a hair treatment based on another reflectance spectrum. A system to measure a reflectance spectrum of a sample includes an integrating sphere having a sampling port and an inner surface and a window disposed near the sampling port. The window is configured for being placed in close contact with the sample. The system also includes a light source configured to project light onto the sample via the window and a light detector configured to analyze light reflected from the inner surface to produce the reflectance spectrum of the sample.
