Semi-permanent coloring does not damage the hair
Unlike permanent colors, semi-permanent color is ammonia-free and does not require oxidants (sometimes present in low concentration). It does not penetrate the cortex of the hair and does not damage its structure. The pigments, vegetable or not, create a film around the hair, attach themselves between the scales and form a protective sheath, without altering the natural base color and without modifying the natural pH.
It therefore does not affect the fiber and it is not very aggressive for the scalp and the hair, which makes it the ally of people with damaged hair or allergic to colorings. There are semi-permanents with natural or classic ingredients.
Semi-permanent coloring covers (partially) white hair
The tone-on-tone color can cover between 50 and 70% of white hair, but not at all like a permanent color that recolors them from the inside. Here, the pigments arise on the hair in a natural way and in transparency, so that we avoid the clear demarcation of the root effect during regrowth.
Semi-permanent color fades gradually
As it does not penetrate the heart of the hair, this color leaves gradually over washes and lasts about 10 shampoos or six to eight weeks. It fades without leaving a root effect, so no need to touch up regrowth every four to six weeks.
Semi-permanent hair color enhances color
This type of coloring is superimposed on the color of the hair. The result therefore varies depending on the base shade, quality and pH of the hair. It allows you to sublimate the natural color by accentuating reflections, to neutralize unsightly reflections, to revive the shine of the hair or to make up for color or discoloration. It does not bleach, but can darken two tones. You can also use it to test a color before taking the plunge.
How is it maintained?
To prevent the color from fading too quickly, the ideal is to wait 2 to 3 days before your first shampoo, to use a product without sulphate or clay to wash the hair gently and do not ” wash”, with a mask (without coconut oil, because it absorbs pigments) in addition once a week.
>> And the temporary camps? There are also so-called temporary colorings, even more fleeting, which leave in two or three shampoos. In particular, they allow you to try on trendy or very flashy colors (pink, blue, green, gold, etc.).
