What Is Demi-Permanent Hair Color?

Demi-permanent hair coloring dye contains little or no peroxide or ammonia and the coloring results last for up to 20 shampoos.

Availability

Demi-permanent hair color is purchased from a drugstore or grocery store and used at home. A professional coloring stylist can also apply the dye at a salon.

Procedure

Demi-permanent hair coloring dye is applied to the hair shaft and penetrates between the cuticle, or outside layer of hair, and the cortex, which is the second outermost layer of hair.

Benefits

Users of demi-permanent hair color can lighten their natural hair color, according to Salon East NYC. This hair coloring product also deposits rich tones of color and temporarily covers gray hair.

Considerations

Demi-permanent hair coloring dye does not last as long as permanent hair color, so more touch-ups could be needed to hide gray hairs.

Risks

Overuse of demi-permanent hair dye may contribute to hair damage that leaves the hair shaft prone to breakage.
