Highlights are simply pieces of hair that are lighter than your natural color using lightener or hair color to color hair strands. The actual color change from highlighting is, in effect, permanent. Hair lightened with bleach or permanent color will be permanent until new growth begins to growth. Most people find that they need to have their highlights retouched every six to eight weeks.
There are four basic types of highlights:
Foil highlights: Foil highlighting is the process of using foil to separate strands of hair which will be lightened from strands of hair which will remain its natural color. The process is done by applying lightener to the hair that has been woven and separated using an applicator brush. The foil is then folded to protect the hair and surrounding area during the processing time
Hair painting: Hair painting is a method of highlighting hair that may be done at home.Hair painting methods are often permanent and employ a simple hair-painting brush.
Frosting: Frosting is the process of free-hand lightening the tips of the hair, and is generally performed on men or women with short hair.
Chunking: Chunking is a style of highlight which is larger and thicker than a traditional highlight, rather than to a method of creating highlights.
