Glossary Mechanical Strength

ability to resist breaking or deforming under force

Mechanical strength refers to the ability of a material to withstand forces or loads without breaking or deforming. In the context of hair, it indicates how well hair fibers can resist damage from physical actions like brushing, pulling, or styling. For professionals, it encompasses properties such as tensile strength, elasticity, and resilience, which are critical for understanding hair health and the effectiveness of hair care products.
