GlossaryElliptical Cross-Section

shape of hair strand cut perpendicularly, revealing an oval outline

An elliptical cross-section refers to the shape of a hair strand when it is cut perpendicular to its length, revealing an oval or elliptical outline rather than a perfect circle. This shape is often associated with curly or wavy hair, as the asymmetry can influence the hair's curl pattern and texture.
