Eurofins SPINCONTROL has strong expertise (35 years) in the field of cosmetic testing: facial care, body care, makeup, hair care, and emotional responses. When it comes to hair care, we have specific expertise in testing hair fibers, whether on hair strands (bleached, damaged, etc.) or in vivo. We conduct instrumental evaluations, including (among other things) measurements of repairing and strengthening effects, as well as measurements of breakage, manageability, dryness, thermal protection, and anti-frizz properties.
