Which statement is true about demi-permanent color?

• A. It lasts 4-6 weeks.
• B. It lasts 8-12 weeks.
• C. It lasts 1-2 days.
• D. It lasts permanently.

Answer: (A)

Demi-permanent color is deposit-only color that gradually fades with washing, typically lasting four to six weeks. It uses a gentler developer to open the cuticle just enough to deposit pigment, but it does not lift the natural hair color or create lasting bonds, so the color lightens and eventually washes out over time. That makes the four-to-six-week duration the correct description. It wouldn’t last eight to twelve weeks like permanent color, nor just one to two days, since it’s designed to stay in the hair for multiple washes. It also isn’t permanent because the pigment gradually fades and is eventually gone after repeated shampoos.
