Hair Color 101: The Difference Between Semi-Permanent and Permanent

It’s easy to be overwhelmed with all the hair color options available. Endless shade ranges, trendy coloring techniques, and the abundance of brands that take up shelf space are enough to confuse even the most knowledgeable beauty consumer. But perhaps the most important decision to make about hair color is choosing between semi-permanent and permanent application.

Semi-Permanent

Semi-permanent hair color is a less invasive way to color your hair, as it coats the hair shaft without permanently altering natural hair color or melanin. It only grazes the cortex of the hair at surface level, allowing you to try various hues without a lengthy commitment. True to its name, the color fades relatively quickly depending on how frequently you wash your hair.

Semi-permanent application can provide a more natural-looking, high-shine color. The formula does not contain bleach, so it won’t lighten your hair, but it can be applied to pre-lightened hair allowing for more vivid results. Free from harsh chemicals like hydrogen peroxide or ammonia, semi-permanent colors are a great option for maintaining optimal hair health.

Permanent Hair Color

Permanent hair color can lighten, darken, or change the tone of your hair. It requires oxidation to work. Ammonia and Hydrogen Peroxide work together to open the cuticle, interact with melanin and keratin, and change the structure of the hair to deposit and lock the color deep in the cortex. It doesn’t wash out with shampoo; it simply fades over time.

Typically, permanent hair color lasts approximately six to eight weeks, making it a great option for covering and blending gray hair. As the permanent hair color grows out, roots become more noticeable (especially if you went lighter than your natural shade) and will require a touch up, sometimes as early as four weeks.

Which Hair Color is Right for You?

Ultimately, the type of hair color application you choose is a personal decision. If you are hesitant about keeping the same hair color for a long period of time, then semi-permanent is the way to go. Satin has more than 70 shades of hair color to choose from, each formulated to ensure 100 percent gray coverage. Its micro color molecules provide exceptional saturation for seamless coverage and longer-lasting results. The proprietary blend of Aloe Vera and Soy Protein condition hair during the color process, leaving it healthy and shiny. The 1:2 mixing ratio allows for multiple applications per tube, making Satin one of the most cost-effective hair color brands available.
