Preparation of evaluation supports

At SP Equation, we design custom-made hair swatches to ensure reliable, reproducible, and tailored instrumental evaluation tests. We put our expertise at the service of your projects by assisting you in defining your samples and finding the most appropriate technical and economic solutions.

We prepare:

• Natural hair strands: custom supply and manufacturing based on origin, naturalness, color, or percentage of gray hair.
• Sensitized hair: chemical treatments such as bleaching, perming, or mechanical or UV sensitization.
• Specific samples: development of customized solutions adapted to hair, cosmetic, or makeup testing (e.g., scaffolds imitating eyelashes).

Each parameter is fully customizable: ethnicity, pigmentation, degree of curl, type of attach, dimensions, or even treatment applied, for a solution tailored to each evaluation protocol.
