What To Know About Hair Coloring

By Irma Farrell

Hair coloring refers to the act of changing the color of the hair. The main purpose for doing this is cosmetic. That is, covering up locks that have gone gray, restoring original shade after bleaching or other processes have changed the color, or to stay on trend with what is most fashionable and desirable. This type of dying is an ancient art that utilizes a variety of 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 numerous techniques that might be employed during this practice too. The various methods might impact the end results. Foiling involves using plastic film or foil to separate hair that is colored. This is particularly useful when it comes to applying multiple colors. A plastic cap may be employed, this fits around the head and strands are then pulled out using a hook. Balayage, dip-dying and tipping all involve direct application of the dye onto strands without foil. All such methods can be used for any color of dye.

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 kinds only partially penetrate the shaft. For this reason, the color is able to survive more than one wash and usually lasts for a few weeks or four of five washings. These include low amounts of ammonia, peroxide or developer, or none. They are safer for locks that are fragile or damaged.

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 popular, particularly in America. It is done by both women and men, of all ages. It involves altering the natural color of their locks. This can be done through use of many different dyes and processes, which are usually: semi-permanent, permanent, temporary or demi-permanent. Professionals may do the coloring for their clients or individuals may purchase a kit to use at home and do it themselves.
