Haircare is a comprehensive term for hygiene and cosmetology involving hair that grows from a human scalp, and to a lesser extent on the face, pubic hair and other body hair. Hair care routines differ according to individual culture and physical characteristics of a person's hair. Hair can be tinted, trimmed, shaved, picked, or thrown away with treatments such as waxing, sugaring, and threading. Hair care services are offered in salons, barbers and day spas, and products are commercially available 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 specialty spas.

Hair cleansing and conditioning
Biology and cleanliness
Hair care and scalp care may appear to be separate, but are actually intertwined because hair grows from beneath the skin. The parts of the living hair (hair follicles, hair roots, root sheath, and sebaceous glands) are under the skin, while the actual hair shaft appears (cuticle covering the cortex and medulla) has no living process. Damage or changes that occur in the hair shaft are visible can not be repaired by biological processes, although much can be done to regulate the hair and ensure the cuticle remains intact.
The scalp skin, just like any other skin on the body, should stay healthy to ensure a healthy body and healthy hair production. If the scalp is cleaned regularly by those who have rough hair or have hair loss problems, it can cause hair loss. However, not all scalp disorders are a result of bacterial infection. Some appear unexplained, and often only treatable symptoms for the management of the condition (eg dandruff). There are also bacteria that can affect the hair itself. Head lice may be the most common hair and scalp disease worldwide. Head lice can be removed with great attention to detail, and studies show it is not necessarily associated with poor hygiene. More recent research reveals that hair lice thrive with clean hair. In this way, hair washing as a term may be a bit misleading, as what is required in the production and maintenance of healthy hair often only cleans the surface of the scalp, the way the skin throughout the body requires cleaning for good hygiene.
The sebaceous glands on the human skin produce sebum, which mainly consists of fatty acids. Sebum acts to protect hair and skin, and can inhibit the growth of microorganisms on the skin. Sebum contributes to a slightly acidic natural pH somewhere between 5 and 6.8 on the pH spectrum. This oily substance provides moisture and luster of hair as it flows naturally to the hair shaft, and serves as a protective agent by preventing hair from drying out or absorbing excessive amounts of external substances. Sebum is also distributed to the hair shaft "mechanically" by brushing and combing. When sebum is excessively present, the roots of the hair may appear oily, greasy, and darker than usual, and hair can stick together.
Hair Cleaning
One way to distribute the natural oil of hair through hair is by brushing with a natural bristle brush. Natural hair effectively removes oil from the scalp down to the center of the hair and the tip, nourishes the hairs. Scalp brushing also stimulates the sebaceous glands, which in turn produce more sebum. When sebum and sweat are mixed on the surface of the scalp, they help create an acid coat, which is a protective layer of the skin itself.
Washing hair removes sweat and excess oil, as well as unwanted products from hair and scalp. Often the hair is washed as part of a bath or shower with shampoo, a special surfactant. Shampoo works by applying water and shampoo to hair. The shampoo breaks the tension of the water surface, allowing the hair to become soaking wet. This is known as the wetting action. The wetting action is caused by the head of a shampoo molecule that draws water to the hair shaft. Instead, the molecular tail of the shampoo is attracted to fat, dirt and oil on the hair shaft. The physical action of shampooing makes fat and dirt an emulsion which is then rinsed with water. This is known as emulsifying action. The sulfate-free shampoo is less harmful to colored hair compared to the usual sulfate-containing shampoo. Sulfate removes natural oils as well as hair dyes. Sulfate is also responsible for the effects of shampoo foam. The shampoo has a pH between 4 & amp; 6. The acid shampoo is the most commonly used type and maintain or improve the condition of the hair because they do not swell the hair and do not disarm the natural oils.
The conditioner is often used after shampooing to smooth the hair cuticle layer, which can become rough during the physical process of shampooing. There are three main types of conditioners: anti-oxidant conditioners, which are mainly used in salons after chemical services and prevent creeping oxidation; the internal conditioner, which enters the hair cortex and helps improve the internal condition of the hair (also known as the treatment); and external conditioners, or everyday conditioner, which smoothed the cuticle layer, making hair shiny, flammable and smooth. The conditioner can also provide a physical layer of protection for hair against physical and environmental damage.

Chemical change
Chemical changes such as crimp, staining can be done to change the color and texture of the felt hair. All of this is a temporary change because permanent changes are not possible today.
Chemical changes in hair only affect hair on the scalp; unless the root of hair is damaged, new hair will grow with natural color and texture.
Hair coloring
Hair coloring is the process of adding pigment to or eliminating pigment from the hair shaft. The process of hair coloring can be referred to as coloring or bleaching, depending on whether you add or remove pigments.
While the hair tints simply coat the shaft with pigment which then wash.
The most permanent color change requires the hair cuticle to be opened so that discoloration can occur inside the cuticle. This process, which uses chemicals to change the hair structure, can damage the cuticle or the internal structure of the hair, making it dry, weak, or easily broken. After the hair process, the cuticle may not be completely closed, resulting in coarse hair or pigments that disappear quickly. Generally, the brighter the color chosen from one's initial hair color, the more damaged it becomes. Other options to apply color to hair other than chemical dyes include the use of herbs such as henna and indigo, or opt for ammonia-free solutions.
Perm and chemical alignment
Perm and relaxation using a relaxer or thermal recondition involves a chemical change of the internal structure of the hair to affect neatness or straightness. Hair that has been subjected to permanent use is weaker due to chemical applications, and should be treated gently and with better care than hair that is not chemically modified.
Special considerations for hair type
Long hair
Many industries have requirements for hair conceived to prevent worker injury. These can include people who work in construction, utilities, and machine shops of various types. In addition, many professions require hair for public health reasons, and the main example is the food industry. There are also sports that may require similar obstacles for security reasons: to keep hair out of the eye and block someone's view, and to prevent being caught in sports equipment or trees and shrubs, or tangled hair in bad weather or water conditions. Safety is usually the reason behind not letting hair loose on the back of motorcycles and sports cars that are open for longer tress.
Delicate skin
The scalp skin baby and parents are similar in the production of calm sebaceous glands, due to hormonal levels. The sebaceous glands secrete sebum, the wax ester, which retains the acid mantle on the scalp and provides a layer that keeps skin supple and moist. The sebum builds up too, between every 2-3 days for the average adult. Those with fine skin may experience longer intervals. Teenagers often need to wash their hair every day. Sebum also implant a protective layer for hair strands. Daily washing will remove sebum every day and trigger an increase in sebum production, as the skin sees the scalp skin is not moist enough. However, in case of a scalp disorder, this is unlikely to happen. For infants and elderly, the production of sebaceous glands is not at the peak, so daily washing is not usually necessary.
Treatment of damage
Split the end
Split ends, known formally as trichoptilosis , occur when the protective cuticle has been stripped from the ends of the hair fiber.
This condition involves longitudinal cleavage of the hair fiber. Any chemical or physical trauma, such as heat, which dries hair can ultimately lead to a forked tip. Usually, the damaged hair fiber is divided 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 the hair grows, natural protective oil from the scalp can fail to reach the tip of the hair. The edges are considered old after reaching about 10 cm because they have long been exposed to the sun, past many shampoos and possibly overheated by hair dryers and hot irons. This all produces a dry and fragile tip that tends to rupture. Uncommon trims and lack of hydrating treatments can intensify this condition.
Other damage and damage
Hair can be damaged by chemical exposure, prolonged or recurrent heat exposure (such as through the use of hot styling tools), and by crimp and straightening. Oil is harmful to coarse hair and to dry scalp as it reduces food for hair that divides and hair loss. When hair behaves in an unusual way, or a scalp disorder appears, it is often necessary to visit not only qualified doctors, but occasionally dermatologists, or a psychiatrist. Conditions that require this type of professional help include, but are not limited to, the form of alopecia, pulling/picking hair, straight hair, black dots on the hair, and rashes or burns resulting from chemical processes. The gel provides a glistening appearance but dries hair and makes it rough.
There are a number of disorders that are specific to the scalp. Symptoms may include:
- An abnormal smell
- Bleeding
- Bump
- Compile a white skin buildup or other color from someone's natural skin tone
- Chafes
- Blobs of hair fall off
- A thick flake that does not easily peel off the scalp
- Dandruff and clumps
- Dry & amp; scalp
- Excessive itchiness that does not go away with some hair washing, redness on the scalp
- Thinning filling
- Streams like pussy
- Shedding
These symptoms may indicate the need for professional help from a dermatologist or obstetrician for diagnosis.
Scalp skin can suffer from infestation of mites, lice, infections of the follicles or fungi. There may be an allergic reaction to the ingredients in the chemical preparations applied to the hair, even the ingredients of the shampoo or conditioner. General concerns about dandruff (often associated with excessive sebum); psoriasis, eczema, or seborrheic dermatitis.
The odor that lasts for several weeks although washing hair regularly can be an indication of health problems on the scalp.
Not all flakes are dandruff. For example, some can only be a buildup of products on the scalp. This can occur due to the general practice of applying conditioner to the scalp without washing. It will dry the scalp and peel, appear like dandruff and even cause itching, but it has no health effects whatsoever.
There are various reasons for hair loss, most often a hormonal problem. Hormonal fluctuations will often appear in the hair. Not all hair loss is related to what is known as male pattern baldness, women can suffer from baldness just like men. The formula to address the causes of less specific hair growth usually requires about three months of consistent use in order for the results to begin to appear. Termination also means that the growth gained may disappear.
Especially among women, thyroid disease is one of the underdiagnosed health problems. Hair loss is one symptom of a set of symptoms that may indicate thyroid worries. In many gynecological examinations, the blood screen for the thyroid is now a common protocol. The thyroid often appears first in hair behavior.
During pregnancy and lactation, normal and natural shedding processes are usually suspended (starting around the third month as it takes time for the body to recognize and rearrange for body hormonal shifts to pass through) for the period of pregnancy and extended again if one breast feed (this includes pumping breast milk ). After discontinuation of one, it usually takes about two months for the hormone to shift back to normal hormonal regulation, and hair shedding can increase exponentially, for about 3-6 months until the hair returns to its normal volume. It is generally noticed that the hair looks thicker and more shiny, even, during pregnancy and lactation in response to the influx of shifting hormones. It is not unusual if hair color changes, or hair structure changes (eg straight hair, curling hair). This change may occur more often than might be realized but not often reported.
Common hair loss
Some choose to shave their hair completely, while others may have a disease (such as a form of cancer - note that not every form of cancer or cancer treatment means a person will lose his hair) that causes hair loss or causes a shave decision. Hair and nutritional treatment
Genetics and health are factors in healthy hair. Proper nutrition is important for healthy hair. The part of the living hair is under the scalp where the hair root is placed in the hair follicle. All follicles and roots are fed by arterial supply, and blood carries nutrients to the follicles/roots. Whenever an individual has any health problems from stress, trauma, various medications, chronic medical conditions or medical conditions that come and subsequently decreases, heavy metals in water and food, smoking etc. This and more can affect the hair, growth, and appearance.
Generally, eat whole foods containing protein, fruits, vegetables, fats, and essential carbohydrates (some vitamins and minerals need fat to be channeled or absorbed by the body). Any deficiency will usually be seen first in the hair. Mild cases of anemia can cause hair loss and hair loss. Among other things, group B vitamins are the most important for healthy hair, especially biotin. B 5 (pantothenic acid) provides flexibility of hair, strength and luster and helps prevent hair loss and graying. B6 helps prevent dandruff and can be found in cereals, egg yolks and liver. Vitamin B 12 helps prevent hair loss and can be found in fish, eggs, chicken and milk.
When the body is tense, he prioritizes the process again. For example, vital organs will be attended first, which means that healthy and oxygenated blood may not enter the hair follicle, resulting in less healthy hair or decreased growth rates. Although not all hair growth problems come from malnutrition, it is a valuable symptom in diagnosis.
Scalp hair grows, on average, at a rate of about 1.25 centimeters per month, and shampoo or vitamins have not been proven to significantly change this level. The rate of hair growth also depends on what phase in the actual hair growth cycle exists; there are three phases. The rate of hair growth varies by genetics, sex, age, hormones, and can be reduced by nutritional deficiencies (ie, anorexia, anemia, zinc deficiency) and hormonal fluctuations (ie, menopause, polycystic ovary, thyroid disease).
Essential omega-3 fatty acids, protein, vitamin B 12 , and iron, are found in fish sources, prevent dry scalp and dull hair color. Dark green vegetables contain lots of vitamins A and C, which help produce sebum and provide a natural hair conditioner. Nuts provide protein to promote hair growth and also contain iron, zinc, and biotin. Biotin serves to activate certain enzymes that help the metabolism of carbon dioxide as well as proteins, fats, and carbohydrates. Deficiency in biotin intake can cause brittle hair and can cause hair loss. To avoid deficiencies, individuals can find sources of biotin in grain products, liver, egg yolks, soy flour, and yeast. Nuts contain a high source of selenium and are therefore important for healthy scalp. Alpha-linolenic acid and zinc are also found in some nuts and help condition the hair and prevent hair loss that can be caused by zinc deficiency. Lack of protein or low-quality protein can produce weak and brittle hair, and eventually can result in hair loss. Dairy products are a good source of calcium, a key component to hair growth. A balanced diet is necessary for healthy scalp and further healthy hair.
