Development of a methodology to evaluate internal hair porosity using scanning electron microscopy – Webinar 6 August

The investigation of hair porosity and the effect of cosmetic products on this parameter for claim substantiation has traditionally relied on indirect measurements. This is primarily because the techniques available for direct assessment require specialized and expensive equipment, making them unfeasible for routine commercial use. However, understanding and addressing hair porosity is critical for cosmetic companies as it directly impacts the overall integrity of the hair fiber and influences consumer satisfaction. Porosity affects how well hair retains moisture and how it responds to treatments, which is crucial for the long-term performance of hair care products.

Recently, with the advancement of image analysis software and plugins, new methods have emerged to more directly evaluate hair porosity. One promising approach is the use of cross-sectional images of hair fibers obtained through SEM (Scanning Electron Microscopy). This method allows measurement of the internal porosity of the hair fiber, offering a more direct and precise analysis. However, the main challenge lies in obtaining high-quality transverse cuts of the hair that preserve the internal structure for accurate measurements.

Given these developments, the goal of this study is to establish a reliable, cost-effective methodology for measuring the number and size of pores in hair fibers. The proposed methodology involves obtaining precise hair cross-sections using advanced histological techniques, followed by image analysis through specialized plugins to count and measure the pores.
