Hair Coloring | Color Hair

      We've all wondered what it would be like to have a different hair color, but maybe
you're not ready for the commitment to make a drastic change. And maybe you aren't
sure if you can achieve the color you want without doing something permanent. Here's
some information to help you understand the types of haircolor available to you.

Temporary Color:

      These products are truly temporary, and are usually sold as color rinses. They're
used most often to cover or mask gray hair, or to add a subtle (or even a bold) tone to
your natural color. Temporary color sits on the outside of the cuticle and adds color to
the surface of the hair. Temporary haircolor won't take you from a darker shade to a
lighter shade, but it can add some depth and richness to lighter hair. Temporary colors
rarely last beyond your next shampoo. Temporary haircolor can be found in a variety of
products: rinses which add color to the hair and are styled dry, color mousses which add
subtle color tones, hair mascara for dramatic effects, spray on colors for controlled
application, and even color-tinted shampoos and conditioners to add depth and longevity
to colored hair.

Semi-Permanent and Demi-Permanent Color:

      Semi-permanent and demi-permanent haircolors are similar in the way they work,
but slightly different in their formulation.

      Semi-permanent color is designed to deposit color onto the hair only and has no
lightening effect. The formula includes an activator that develops the color and helps to
raise the cuticle of the hair shaft so that the color can be deposited there. Semi-
permanent color doesn't penetrate into the cortex of the hair, but it will usually last from
six to eight weeks, gradually washing out with each shampoo.

      Demi-permanent color is also a deposit-only color with no lightening effect. The
difference between the Semi- and Demi-permanent colors is that with demi-permanent
color the color molecules are smaller and therefore penetrate into the cortex of the hair,
as well as being deposited on and in the cuticle. This makes demi-permanent color a
better choice for covering gray hair. The color achieved also lasts longer, but will fade
due to the formulation of smaller color molecules being able to come back through the
cuticle with each shampoo.

Permanent Color:

      Permanent colors are designed to penetrate the hair shaft and deposit their color
directly into the cortex of the hair. The formula contains a developer to raise the cuticle
and allow the color molecules to penetrate into the cortex, and also contain aniline
derivatives which combine with hydrogen peroxide to produce larger tint molecules which
are then trapped inside the cortex.

      By virtue of their formulation, permanent haircolors are able to deposit color, but
can also be used to lighten the color of the hair, depending upon the strength of the
hydrogen peroxide used as a developer. If the desired result is simply the addition of
color with no lightening in level, then your colorist will typically use a 10-volume peroxide
developer. To lighten the hair one-to-two levels and add a color, 20-volume peroxide will
be good. 30 and 40-volume peroxides are available to lighten the base level even
more, but remember that the stronger the peroxide the harsher the effect on your hair.
It is best that you never use anything stronger than 20-volume peroxide developer
without the assistance of a professional to closely monitor the results.
