Abstract: Systems and methods for computing a hair-coloring composition (HCC) or for dispensing ingredients for the HCC are disclosed herein. In some embodiments, the system comprises a hair-treatment objective-prioritization user interface (HTOP UI) for receiving multi-objective relative-importance data describing a relative importance of different hair-treatment objectives (e.g. immediate post-treatment accuracy versus auxiliary goals, or one auxiliary goal versus another) for a potential hair-coloring treatment. In some embodiments, a hair-coloring-composition (HCC) prediction-engine is responsive to input received via the HTOP UI to compute, from the initial hair-state data and from the target color-state, a customized hair-coloring composition predicted to transform a color state of the user's hair from the initial color state to the target color state. This may be performed according to the multi-objective relative-importance data.

Abstract: The present disclosure relates to devices and methods for analyzing hair and/or predicting an outcome of hair-coloring treatment. disclosed is method of predicting a result of a hair-color-modifying treatment on a sample of hair, the method comprising: a. for each given region of a plurality of distinct regions, respectively measuring a region-specific spectrum of respective material of the hair-sample respectively disposed within the given region; and b. computing first and second predicted post-treatment spectra respectively from first and second initial spectra by respectively predicting a transformation of the first and second initial spectra following subjecting the sample of hair to the hair-color-modifying treatment, the first and second initial spectra being distinct and (i) derived from the plurality of measured region-specific spectra and/or (ii) corresponding to first and second of the measured region-specific spectra.

Abstract: A support device configured to be coupled to a dispensing container that includes a tilt valve stem for dispensing a cosmetic cream. The support device includes a cap made of a plastic material that includes an opening for receiving the tilt valve stem and an outer surface configured to attach to the dispensing container, wherein the outer surface attaches to the dispensing container via threads; and a valve configured to be disposed between an inner surface of the cap and the tilt valve stem, the valve being configured to reinforce a return force experience by the stem.

In some embodiments the method comprises: a. performing a plurality of light-scattering measurements upon a sample of hair such that for each light-scattering measurement, the sample of hair is illuminated from a different respective direction; b. comparing the results of the light-scattering measurements; c. in accordance with results of the comparing, computing an initial damage-state of hair of the sample by comparing the results of the light-scattering measurements; d. obtaining an initial color-state of the hair of the sample; and e. computing a hair-coloring composition that is predicted to transform the hair sample from the initial color-state to a target color-state such that in response to a determining of a greater (lesser) extent of initial damage, a concentration of artificial-colorant(s) within the computed coloring composition is reduced (increased).

Abstract: The present disclosure relates to hair readers, dispenser devices, and related systems and methods. For example the present application relates to a method of optically acquiring data from keratinous fibers, the method comprising: a. illuminating the keratinous fibers such that light reflected and/or deflected and/or transmitted by the fibers is incident upon a detector and converted into electrical signals by the detector; and b. computing, from electrical signals, a plurality of spectra of the keratinous fibers such that each spectrum of the plurality of spectra respectively corresponds to (i) a different respective portion of the keratinous fibers and/or (ii) material within a different sub-region of space within which at least a portion of the keratinous fibers are disposed.

Abstract: A system for optically acquiring data from hair comprises a hair-holder including: upper and lower plate assemblies respectively having downward-facing and upward-facing opposing surfaces defining a gap therebetween, the lower plate assembly having a window-void therein, the upper plate assembly further comprising a sideward-facing sample-thickness-regulating surface above the gap; and an alignment-wall mechanically coupled to both plate assemblies and having a side-facing alignment surface within gap or sideward-facing into the gap, the alignment surface being straight along a longitudinal direction parallel to both of the opposing surfaces, the hair-holder being configured so that: when an externally-tensioned sample of hair is loaded onto the hair-holder by laterally moving the sample towards the alignment surface, a presence of the sideward-facing sample-thickness-regulating surface regulates an amount of hair permitted to enter the gap, thereby regulating a thickness of hair above the window-void to at l
