A hair color rinse contains color pigments that stain the outer layer (cuticle) of the hair. Hair color dyes contain color molecules that deposit into the middle layer (cortex) of the hair through a chemical process.

You apply a rinse to damp hair after shampooing, whereas you apply dye to dry hair. Application depends on the condition of the hair and the consumer's desired outcome.

The cost of a professionally applied rinse ranges from $10 to $20. A professionally applied color dye ranges from $35 to more than $100. Factors for the broad price range include: length of hair, precolor treatments and technique, such as basic color or highlights.

According to KidsHealth.org, “At any age, any chemical or heat applied to the hair can damage the hair or cause it to break off.”

A rinse is temporary, lasting five or six shampoos. Dye is permanent, with the chemicals becoming part of the hair.

You can reapply a rinse at any time. Touch up your dye every four to six weeks.

At-home coloring can result in unwanted color results.
