There are several categories of highlights, depending on their use, style and installation technique. Here are the main ones:
1. Classic highlights: These are highlights that lighten the hair by a few shades. They are often done with a bleaching or balayage technique.
2. Balayage: A more natural technique that consists of lightening certain highlights while keeping a darker base. The result is softer and less pronounced than traditional highlights.
3. Fine highlights: These add depth and movement to the hair without changing the base colour too much. These highlights are often discreet.
4. Broad highlights: These offer a more pronounced contrast. Used for a bolder look, they can be of several colours.
5. Ombré: A technique where the roots are darker and the ends are lightened, creating a gradation of colour.
6. Dark / Reverse sweep: This is the opposite of ombré, where the ends are darker than the roots, often used for a dramatic effect.
7. Coloured highlights: These can be any colour (pink, blue, green, etc.) and are often used for a bold, creative look.
8. Metallic highlights: A recent trend where metallic highlights (silver, gold, copper) are added for a futuristic effect.
Each technique allows you to obtain a unique result, depending on your preferences and the nature of your hair.
