WHIT-Semi-Permanent and Demi-Permanent Hair Dye

May 18th, 2012

Have you ever dyed your hair? Ever stood at the store and wonder what the difference was between demi-permanent and semi-permanent hair dye was? It’s simple really! In contrast to permanent dyes, both semi and demi hair dyes are not meant to be permanent-meaning that these colors do not completely penetrate the hair shaft. They are both temporary colors that are meant to enhance but not drastically change your hair color.

Semi-Permanent dyes are milder. They do not contain ammonia or peroxide and are only meant to “stain” or coat a color on the outside of the hair strand. Used for enhancing or changing tones, but not complete colors. They typically last between 6-12 shampoos.

Demi-Permanent dyes are stronger than semi-permanent dyes. It does not contain ammonia but it does, however, incorporate a small amount of peroxide that will open the cuticle only a bit to deposit the color for a longer period of time. Typically between 12-24 shampoos. Demi dyes are good for people who want a more drastic change, though, demi dyes are better for darkening hair rather than lightening it.
