Assessment of hair surface roughness using quantitative image analysis

Area of Science:

• Cosmetic Science
• Materials Science
• Surface Analysis

Background:

• Increasing focus on hair cuticle protection in product development.
• The hair cuticle is crucial for protection but vulnerable to damage.
• Previous cuticle assessment relied on subjective visual methods.

Purpose of the Study:

• To quantitatively analyze hair cuticle changes and roughness.
• To evaluate the effectiveness of hair products using a novel microscopy technique.
• To establish a new standard for hair cuticle analysis.

Main Methods:

• Utilized a HIROX microscope for detailed hair surface imaging.
• Collected hair samples from 23 female subjects over a 4-week period.
• Measured hair roughness parameters before and after product application.

Main Results:

• HIROX microscopy clearly visualized hair surface alterations.
• Significant reduction in hair surface roughness was observed after 4 weeks of daily product use.
• Quantitative data on hair roughness parameters were obtained.

Conclusions:

• The HIROX microscope offers a high-quality quantitative method for hair cuticle analysis.
• This analytical approach represents a new paradigm for assessing hair health and product efficacy.
• The study demonstrates the potential of objective, measurable data in hair care research.
