Demi-permanent hair color is an ammonia-free color option that lasts longer than semi-permanent dyes and fades more quickly than permanent dyes. Demi-permanent hair colors don’t lighten your hair, they only deposit new color on the strand and penetrate the first layer of hair. Curl patterns aren’t altered by demi-permanent dyes, so they’re safe to use on textured hair. Opt for demi-permanent colors when you’re looking for a diffused finish, grey blending, enhancing natural color, highlights, and corrective work.

Demi-permanent color lasts between twenty to thirty washes

Demi-permanent hair color lasts up to thirty washes and permeates the first layer of hair, whereas semi-permanent color is deposit-only and lasts up to twelve washes.

Demi-permanent hair color does not damage curl patterns as other dyes can, and it’s recommended for damaged hair as it contains fewer chemical agents than permanent hair dye.

Apply demi-permanent color to dry hair before you shampoo, and be sure to use the right developer. 

Demi-permanent hair dye can wash out of bleached hair after three to four weeks. Try a clarifying shampoo or color remover for faster results and be sure to condition well.

You should not mix demi-permanent and permanent hair colors as they are manufactured differently and composed of different ingredients that could provide different color effects.

Demi-permanent hair color can be used every six to eight weeks.
