[en] BACKGROUND: The hair shape, either straight, crimp, or curly, is basically under genetic influence. It is possibly altered by some drugs such as cytostatic agents. In addition, specific innate molecular characteristics are modulated by some cosmetic procedures to reshape the hair shafts. AIM: To revisit the possible implication of mechanobiology and cell tensegrity in shaping ethnic hair. MATERIALS AND METHODS: Optical and scanning electron microscopy of hairs. RESULTS: It is generally held that the cross-section shape of hair is related to differences in the global aspect of the hair shaft. A possible biologic link between these features may rely on shaping cell tensegrity at any portion of the hair shaft. Cell tensegrity encompasses all intrinsic and extrinsic forces responsible for the three-dimensional arrangement of intracellular macromolecules. CONCLUSION: We offer as a hypothesis that the hair shape in part depends on the organization of the cell proliferation in the hair matrix. This review gathers observations supporting the involvement of cell tensegrity in shaping the hair shaft.
