Step-by-step explanation:
The technical term for broken hair is trichoptilosis. Trichoptilosis refers to the splitting or fraying of the hair shaft due to damage or excessive dryness. It occurs when the outermost layer of the hair, called the cuticle, becomes damaged and loses its protective function.
For example, frequent use of heat styling tools, chemical treatments, or rough handling of the hair can lead to trichoptilosis. The damaged hair appears dull, brittle, and may have split ends. To prevent trichoptilosis, it is important to practice good hair care habits, such as using heat protectants, avoiding harsh chemicals, and regular trimming of the hair.
