Demi Permanent Vs. Semi Permanent Hair Color. Both demi-permanent and semi-permanent hair color dyes can be applied at a salon or at home. The main differences between demi and semi-permanent hair color are the duration the color lasts and how the dye penetrates the hair shaft. Semi-permanent hair color does not contain any peroxide while demi-permanent hair color may contain low levels of ammonia or peroxide.
While permanent hair dye can lighten your hair up to 2 shades, demi-permanent hair dye is unable to lighten hair at all. The only way to lighten previously colored hair by more than 2 shades is by using lightener. Typically, we recommend applying hair color every 4-6 weeks.
