For a more dramatic change (two or more shades darker or lighter than your natural hair color), a permanent color is a better option. It also works best on coloring gray hair.
Single process is applied to lighten or darken color; this may be permanent, demi- or semi-permanent. (Generally applied to the entire head.)
Lowlights darken select strands of hair, using color darker than your natural color. Provide additional layers of depth or appearance of texture to hair. Less damaging and enhances shine.
Highlights involve colors that are lighter than your natural shade in select strands or segments. Provide enhancement to skin tone and may be used to draw attention to or light up specific areas framing the face.
Both highlighting and lowlighting offer a range of techniques and varieties:
Ombre, meaning "shade" or "shadow" in French, is currently the most popular color application technique. Refers to hair color fading from dark to light, or dark to light. Instead of the color starting from the roots, it gradually becomes lighter, or darker, towards the ends.
Balayage is a French coloring technique to hand paint hair, utilizing fingers, hands, fingers or a spatula to deposit color or lighten.
Foiling means strategically-placed strands painted with a brush wrapped into "foil packets."
Glaze, gloss or toner is a demi-permanent color intended to deposit tone or add shine. Often used to tone hair or refresh color between appointments.
Corrective color is a process performed to correct any damage or unwanted results from previous applications or treatments. Hair that is fragile or in weakened condition requires special care in performing color services and may involve several visits to achieve optimal results.
