Demi-permanent is a type of hair coloring service that lasts longer than temporary colors but isn't as long-lasting as permanent dye. It's a gentle coloring option that typically lasts 24-28 washes. Hairstylists use demi-permanent colors to enhance natural hair color, blend grey hair, or add shine to dulled hair. Unlike permanent hair color, it doesn't contain harsh ammonia and doesn't dramatically change the hair's natural color as it can't lighten hair. It's often called "deposit-only color" or "semi-permanent color" in some salons.
