TRICHORRHEXIS refers to breakage of which structure?

Explanation:
This item tests that trichorrhexis refers to breakage of the hair shaft. The prefix tri- refers to hair (tricho-), and -rrhexis means rupture or breaking, so the term describes rupture within the hair fiber rather than nails, bones, or skin. You’d see frayed, rough, or node-like areas along the hair shaft where it has split or snapped, making the hair weak and easy to break. This condition points to a weakness in the hair’s structure—often the cortex—caused by chemical processing, heat, mechanical brushing, or certain genetic keratin defects. It’s a hair problem, not a nail, bone, or skin issue.
