Horizontal Hair Coloring Segmentation for Root Growth Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair coloring methods require frequent reapplication to maintain color, especially at the roots, which is time-consuming and costly, and can result in uneven color distribution due to amateur application challenges and the visibility of growing darker roots.
Innovation Solution
A method involving the application of a color-altering material to thin horizontal sections of hair using a specialized tool, allowing the material to bond with the hair without covering the natural color, extending the time between color applications and achieving a banding effect that integrates root growth into the overall hair color pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If color-altering material is applied to entire hair body using traditional brush method, then color coverage is achieved, but frequent reapplication is required due to visible roots and uneven color distribution
Solution Approach 1:
The hair is divided into multiple thin horizontal slices rather than treating the entire hair body as one unit. Each slice is independently colored, creating distinct color bands that grow out uniformly, eliminating the visible root line problem and reducing reapplication frequency.
Solution Approach 2:
The coloring approach transitions from vertical application (brushing from roots to ends) to horizontal slicing (creating layers perpendicular to hair growth). This dimensional change allows color to be distributed evenly across each slice, creating a more natural growth pattern that maintains appearance longer.
2Stability of the object's composition
If color-altering material is applied frequently to maintain root color, then overall color consistency is maintained, but time and expense increase
Solution Approach 1:
By segmenting hair into horizontal slices, the color application creates multiple distributed color zones rather than a single root line. This segmentation allows the color to grow out in a stepped pattern that maintains visual consistency for longer periods between applications.
Solution Approach 2:
Different horizontal slices receive color treatment at different levels, creating local variations in color placement. This local quality approach ensures that as hair grows, the color distribution remains visually consistent throughout the hair shaft rather than concentrating at the roots.
3Shape
If traditional highlighting or frosting techniques are used to enhance natural color, then dimension and depth are added, but roots still appear darker over time and hair looks blotchy
Solution Approach 1:
The hair is segmented into numerous thin horizontal slices rather than treating it as a single mass. This fine segmentation allows for uniform color distribution across each slice while maintaining the natural gradient effect, preventing the blotchy appearance associated with traditional highlighting.
Solution Approach 2:
The invention introduces horizontal slicing perpendicular to the traditional vertical coloring approach. This creates multiple color bands at different heights, adding dimension and depth while ensuring uniform color distribution that eliminates the blotchy look and visible root line.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method reduces the frequency of hair coloring sessions to every 3-6 months, providing a cost-effective and aesthetically pleasing banding effect that blends with the natural hair color, minimizing the appearance of growing roots and reducing application time and expense.
Implementation Method 1
the material is applied in a step-by-step manner, often requiring a waiting period to allow the chemicals in the color-altering material to react and for the material to bond with the hair
Data Source
AI summary
Described herein are methods for applying a color-altering material to the roots of the hair which reduce the amount of time needed between color applications. The color-altering material is applied horizontally with respect to the hair, and the natural color of the hair is left intact between the color-altering sessions. The methods of this disclosure incorporate the root growth into the overall color pattern of the hair, allowing a user to wait for a longer period of time in between color applications.
