Hair care is an overall term for parts of hygiene and cosmetology involving the hair on the human head. Care of the hair and the scalp skin are often separate, but in the care of hair are intertwined of necessity since the hair springs forth from under the skin. The alive part of hair is the hair follicle which contains the hair root, the sebacious gland, the vessel for delivering nutrients (via the blood), and other parts. Hair itself is dead; however, much can be done to manage hair such that the outer surface of hair, the cuticle, will remain in tact and protecting the inner parts of the hair shaft: the cortex and the medulla. Hair care means for many a visit to a professional stylist. The discussion of hair is a major world industry from the salon to products to advertising and even magazines on the subject. Indeed, it is displayed and discussed in various forums available on the internet. The most important element of hair care is one's hair type. Hair care will differ according to one's hair type and according to various processes that can be applied to hair. All hair is not the same; indeed, hair is an expression of human diversity on the planet.
When hair behaves in an unusual way, or a scalp skin disorder arises, it is often necessary to visit not only a qualified physician, but may become necessary to visit a dermatologist, or a trichologist. Examples would include but are not limited to forms of alopecia, hair pulling/picking, hair that sticks straight out, black dots on the hair, and rashes or burns resulting from chemical processes.
Hair care also includes hair dressing, where the hair is blown dry, combed and/or styled. Hair dressing may include perms, weaves, coloring, extensions, permanent relaxers, permanent waves, curling and any other form of styling or texturing. Styling tools may include flat irons, curling irons, hair dryers, flat brushes, round brushes, hair rollers, and diffusers and various types of scissors. Hair dressing might also include the use of product to add texture, shine, curl, volume or hold to a particular style. Hair care, for this entry is focused upon hair on the human head, yet mention should be made of other services available in salons such as barber shops which include men's beard and skin care for the beard, and possibly also waxing services of other sites on the human body where hair may be removed. This can also be done via laser applications, but often this is not offered in a salon and is conducted under physician care. Hair dressing, and resulting care requirements in many ways is often more strongly associated with the female gender, but hair care and dressing is no longer just for females. Indeed, many males benefit from improved care considering that males also color (music industry, to cover gray) and enjoy alternative shapes and styles, too.
Haircuts may also include services mentioned under hair dressing. Cutting hair is a way of creating a specific shape and form, and to maintain such sculpture. It can also be used to define a hemline along the ends and edges of longer lengths and amongst longer lengths. Hair cutting may indeed cover shaving the head, and then scalp skin care will be required. In some settings, hair cutting, creating forms and shapes are an expressive art form. Hair cutting often involves considerations of body proportions, hair density and hair type, face and head shape from all views (profile, 3/4 and 360 degree, from above and from below), overall bone structure, and pattern of how hair lies or falls.
Hair shapes and various lengths are often derived from concerns regarding personal expression and aesthetics (examples, dreadlocks, punk hair, the business haircut/style, very long hair), religious (for example, Pentacostal faith among others), social and cultural values. In short, hair is a physical expression of one's sense of themself, how they desire to present themself to and amongst their community, social status and roles, cultural values, and often involves adding ornaments to the hair, or partial or full hair coverings (such as a Kippa, Hijab, or a Turban).
Hair care also includes hair washing, an often necessary practice to cleanse one's hair and scalp skin. Scalp skin that is not cleansed regularly may result in a prime breeding ground for bacteria which sometimes may result in scalp disorders. However, not all scalp disorders are a result of bacterial infections. Some arise inexplicably, and often, only the symptoms can be treated for management of the condition (example, dandruff). There are also bacterias that can affect the hair itself, but in first world countries, this is much rarer. Head lice is probably the most common hair and scalp ailment world wide but can be rid of in time with great attention to detail and studies show it is not necessarily associated with poor hygiene. (Indeed, even well-to-do households can experience head lice. More recent studies reveal that head lice actually thrive in clean hair.) Hair washing as a term may be a bit misleading as what is really necessary is cleaning the surface of the scalp skin, the way the skin of the body requires cleaning for good hygiene. Often hair is washed as part of a shower or bathing with specialized soaps called shampoo. Conditioner is recommended after rinsing out shampoo to replace removed moisture in the hair shaft, the cortex, as well as to protect the hair strands from breakage to impart moisture to the hair and assist with easing detangling and manageability needs.
Scalp hair grows at a rate of about half an inch per month, on average, and shampoos or vitamins have not been shown to noticeably change this rate. Hair growth rate also depends upon what phase in the cycle of hair growth one is actually in (there are three phases). The speed of hair growth varies based upon genetics, gender, age, hormones, and may be reduced by nutrient deficiency (examples, anorexia, anemia, a zinc deficiency) and hormonal fluctuations (examples: menopause, polycystic ovaries, thyroid disease).[1]
