Hairstylescut :: Hair Color Semi Permanent Hair Color
Semi-Permanent colour is terrific for hair-colour first-timers. It washes out in 6 to 12 shampoos,
contains no potentially damaging peroxide or ammonia, and, once its gone, leaves your hair
the same colour as it was before being coloured. This means you can experiment with shades
until you find one you want to use consistently.
Because of its gentle nature, however, semi-
permanent colour can't change things very
dramatically It has a slightly translucent quality
that makes it belter suited to enhancing rather
than altering your natural colour.
What semi-
permanent hair colour can do is take hair one or
two levels darker, or maybe even a shade brighter.
Grey hair, which is notoriously resistant to hair
colour, is rarely well camouflaged by semi-
permanent shades. Furthermore, these shades'
lack of chemicals means they have nolightening power whatsoever.
Use semi-permanent colour to
give hair a change of tone rather than
radically changing your hair colour. If you are a bruntee who dreams of being blonde, semi-permanent color is not for you.
Demi Permanant Hair Color
Demi-permanent hair colour - which some people mistakenly call semi-permanent -
lasts from 12 to 24 shampoos. It contains a small amount of peroxide - which means a
small amount of hair damage - but no ammonia, making demi-permanent colour a
midway option between semi-permanent and permanent colour. True to its middle-of-
the-road position, demi-permanent colour does a bit more than semi-permanent. First
off, it stays in hair longer before fading away. In addition, demi-permanent colour's
slightly more opaque formula does a better job of darkening hair more than three level
, covers grey better, and boasts more power to brighten hair. That tim
amount of peroxide can lighten hair, but only slightly - usually less than half a level.
Again, if you have dark hair and dream of light locks, demi-permanent
colour is not for you.
How do semi permanent hair color fade?
Shampooing loosens their pigment molecules, causing color to progressively diminish untill all the molecules are gone. Because of this, you will never experience tell-tale roots with semi permanent color.
