Once you understand what you want to achieve with color, you can choose the type of product you need to use:
Permanent hair color generally uses both ammonia and peroxide. It opens the cuticle, strips existing color away and then deposits new color, permanently changing the hair’s pigment color. The new shades remains in place until the hair grows out or the color is changed again. This type of color is used to make more drastic hair color changes.
Semi-permanent hair color may or may not contain ammonia or peroxide. It penetrates the cuticle and outer layers of the hair shaft with a new color. The change is effective for between 6 to 10 weeks, less if hair is shampooed every day.
Demi-permanent hair color may or may not contain ammonia or peroxide. It deposits color on the outer cuticle and may penetrate into the hair’s cortex. This type of color lasts about 12 to 20 shampoos.
Temporary hair color usually doesn’t contain ammonia or peroxide. It coats the outside of the hair shaft but does not penetrate into the cuticle. This type of color does not lighten the hair - it is used to deepen or brighten color and washes out in just a few shampoos.
Highlight color lifts color from select strands of hair and deposits a new lighter coordinating color. Because it lifts color, it contains both ammonia and peroxide. Highlights last until the natural color grows back out.
Lowlight color also involves select hair strands, but this time they are made darker than the natural hair color. This type of color may or may not involve ammonia or peroxide. Lowlights also usually last until the natural color grows out.
Color range
Once you know the type of product you need, it is important to know the color range you hope to achieve. Going a shade or two lighter or darker is relatively easy, whereas making drastic changes from black to blonde or vice versa is exceedingly difficult, and should only be done by professionals who know how to protect the hair during the process. Redheads need to be careful when it comes to lightening or highlighting hair. If the process isn’t taken far enough, hair can come out orange. If the wrong colors are chosen, it can take on a green tint. If lightening or darkening is taken too far, it can severely damage the hair.
Match hair color to skin tone
Next, it is important to match your hair color with your skin tone for the most natural looking results. Choosing a hair color tone that is in opposition to the skin tone is, of course, possible. However, the results will look artificial and probably won’t leave you feeling happy about the choice you made. http://www.ultraimports.com.au/legal.php
