Hair care

Image
Hair care is an overall term for hygiene and cosmetology involving the hair which grows from the human scalp, and to a lesser extent facial, pubic and other body hair. Hair care routines differ according to an individual's culture and the physical characteristics of one's hair. Hair may be colored, trimmed, shaved, plucked or otherwise removed with treatments such as waxing, sugaring and threading. Hair care services are offered in salons, barbershops and day spas, and products are available commercially for home use. Laser hair removal and electrolysis are also available, though these are provided (in the US) by licensed professionals in medical offices or speciality spas.

( August 2012 ) (Learn how and when to remove this template message) Biological processes and hygiene Care of the hair and care of the scalp skin may appear separate, but are actually intertwined because hair grows from beneath the skin. The living parts of hair (hair follicle, hair root, root sheath and sebaceous gland) are beneath the skin, while the actual hair shaft which emerges (the cuticle which covers the cortex and medulla) has no living processes. Damage or changes made to the visible hair shaft cannot be repaired by a biological process, though much can be done to manage hair and ensure that the cuticle remains intact. Scalp skin, just like any other skin on the body, must be kept healthy to ensure a healthy body and healthy hair production. If the scalp is cleaned regularly by those who have rough hair or hav

Chemical alteration

Chemical alterations like perming, coloring can be carried out to change the perceived color and texture of hair. All of these are temporary alterations because permanent alterations are not possible at this time. Chemical alteration of hair only affects the hair above the scalp; unless the hair roots are damaged, new hair will grow in with natural color and texture. Hair coloring Hair coloring is the process of adding pigment to or removing pigment from the hair shaft. Hair coloring processes may be referred to as coloring or bleaching, depending on whether pigment is being added or removed. Temporary hair tints simply coat the shaft with pigments which later wash off. Most permanent color changes require that the cuticle of the hair be opened so the color change can take place within the cuticle. This process, which uses chemicals to alter the structure of the hair, can damage the cuticle or internal structure of the hair, leaving it dry, weak, or prone to breakage. After the hair pr

Special considerations for hair types

Long hair Many industries have requirements for hair being contained to prevent worker injury. This can include people working in construction, utilities, and machine shops of various sorts. Furthermore, many professions require containing the hair for reasons of public health, and a prime example is the food industry. There are also sports that may require similar constraints for safety reasons: to keep hair out of the eyes and blocking one's view, and to prevent being caught in sports equipment or trees and shrubs, or matted hair in severe weather conditions or water. Safety is usually the reason behind not allowing hair to fly loose on the backs of motorcycles and open-topped sports cars for longer tresses. Delicate skin Scalp skin of babies and the elderly are similar in subdued sebaceous gland production, due to hormonal levels. The sebaceous gland secretes sebum, a waxy ester, which maintains the acid mantle of the scalp and provides a coating that keeps skin supple and moi

Treatment of damage

Split ends Split ends, known formally as trichoptilosis , happen when the protective cuticle has been stripped away from the ends of hair fibers. This condition involves a longitudinal splitting of the hair fiber. Any chemical or physical trauma, such as heat, that weathers the hair may eventually lead to split ends. Typically, the damaged hair fiber splits into two or three strands and the split may be two to three centimeters in length. Split ends are most often observed in long hair but also occur in short hair that is not in good condition. As hair grows, the natural protective oils of the scalp can fail to reach the ends of the hair. The ends are considered old once they reach about 10 centimeters since they have had long exposure to the sun, gone through many shampoos and may have been overheated by hair dryers and hot irons. This all results in dry, brittle ends which are prone to splitting. Infrequent trims and lack of hydrating treatments can intensify this condition. Breakage
