Which characteristic does NOT describe semi-permanent colors?

• A. Only deposits color
• B. Retouch services are not required
• C. Leaves a line of demarcation
• D. Does not involve a chemical change to alter the hair

Answer: (C)

Semi-permanent color deposits pigment on the hair shaft without lifting the natural color or changing the hair’s structure. It sits on the cuticle and gradually fades with each wash, rather than creating a sharp, lasting boundary as hair grows. That fading behavior means you won’t typically see a pronounced line of demarcation where new growth meets treated hair, which is why leaving a line of demarcation isn’t a characteristic of semi-permanent color. The other statements align with semi-permanent color as well: it deposits color only, rather than lifting, so you often refresh the shade by applying color over the entire strand rather than doing a separate root retouch, and it doesn’t involve a significant chemical change to the hair’s structure since it mainly coats the surface rather than altering the cortex.
