Rotating Hook Hair Coloring Device for Precision Variegation

The patent introduces a comb as an intermediary tool between the technician's hand and the hair sections. The comb's teeth provide a structured interface for selecting and isolating specific hair sections, replacing the unpredictable cap-hole method with a controlled combing action that consistently produces desired hair sections.

The patent replaces the mechanical cap-hole system with a comb-based mechanical system. Instead of relying on fixed holes in a cap, the comb's movable teeth allow dynamic selection and isolation of hair sections through combing motions, providing both consistency and operator control.

The patent segments the coloring process into distinct phases: first using the comb to isolate specific hair sections from adjacent hair, then applying color only to the isolated sections. This segmentation prevents color bleeding while maintaining productivity by working with defined sections rather than attempting to color entire large areas at once.

The comb acts as an intermediary barrier between the color and adjacent hair sections. By using the comb to lift and isolate target hair sections, the system creates a physical separation that prevents color from bleeding onto surrounding hair while allowing efficient color application to the isolated sections.

The patent extracts the essential function of the foil method—isolating hair sections to prevent color bleeding—while removing the time-consuming aspect of actual foil application. The comb provides the isolation function without requiring foil placement, significantly reducing process time while maintaining precision.

The patent applies local quality by using the comb to isolate only the specific hair sections that require coloring, rather than treating all hair uniformly. This localized approach achieves precise color application similar to foil methods but allows for faster processing by working with smaller, comb-isolated sections.

The patent replaces the painful mechanical action of pulling hair through small holes with a gentler combing motion. The comb's broader teeth distribute force across multiple hair strands rather than concentrating it at single points, significantly reducing discomfort while maintaining effective hair section selection.

The comb's flexible teeth can adapt to the scalp contour and hair texture, providing a gentler interaction compared to rigid cap holes. The combing action flexibly engages with hair sections, reducing mechanical stress and discomfort on the recipient's scalp and hair.
