Hair coloring involves changing the color of the locks. This is often done for cosmetic reasons. Many people use it as a way to cover up locks that are beginning to gray, to restore original color of hair that has changed because of different processes, or to stay on trend when what is currently desirable or fashionable around the world. This type of dying has is nothing new. It is considered an ancient practice that now involves the use of many different chemical compounds.

Dying is popular nowadays, particularly in the United States of America. In fact, it is believed that more than three-fourths the population of women do this to their locks. Coloring can be professionally done by cosmetologist and hairdressers or by individuals using special kits purchased from the store.

In the past, color was applied overall in one color. Nowadays, it is more common for gradations, streaks and multiple colors to be used on a base or the natural hair color. These methods are also referred to as lowlighting or highlighting. As its name suggests, highlighting involves using lighteners and lowlighting utilized darker dyes.

There are also different methods that are applied in this process. These can impact how the final look appears. Foiling is done using plastic film or foil to separate hair to be colored, especially in application of multiple colors. Cap is a plastic cap that is placed tightly around the head and strands around pulled out of the cap using a special hook. Tipping, dip-dying and balayage refer to color that is painted directly onto section without use of foils. These techniques can be used with any color.

There are four main classifications for coloring: temporary, semi-permanent, demi-permanent and permanent. Permanent is popular and most often done through application of oxidation dyes. Demi-permanent color is permanent coloring that includes an alkaline component other than ammonia. These cannot be used to color hair lighter than what it was previous to dying, but do not cause as much damage as permanent dyes. These are more effective than semi-permanent dyes when it comes to covering up gray but less effective than permanent products.

Semi types only penetrate the shaft partially. Because of this, the color survives repeated washes, usually between four and five shampoos or a few weeks. These contain low amounts of developer, ammonia or peroxide, or none at all. This is safer for damaged and fragile locks.

Temporary types comes in gels, foams, shampoos, rinses, sprays and other forms. Usually the coloring comes out more vibrant and bright than others. Most people use this for special occasions, including Halloween and costumes. Pigment molecules in dyes are too big to penetrate layers of the cuticle. Instead, the particles of color stay inside the shaft and come out after a wash or two.

Hair coloring is a popular practice, especially in the United States. It is done by males and females, of varying ages. This process involves changing the color of the locks. It can be done through use of different methods and dyes, which may be classified as demi-permanent, temporary, permanent or semi-permanent. Professionals might color the hair or individuals can use a kit to do it.
