Alopecia-Everything that you must know

All About Alopecia

.The hair on the shape of our face and the first impression we give to those we encounter. 
The way interfere, or intervene in them, may also betray a lot about our character: we are wise, revolutionaries, brave, indifferent, practical, daffodils? Even when the hair is rich and healthy, many find difficult to manage so that they match the impression they want to give to others. If you start to thin out considerably, the options are limited, which impacts on confidence. If they are serious, can cause psychological and social effects, especially in people who combine data, personality.

.THE RIGHT ShampooThe daily shampooing, if done gently, not damage hair.
 Frequency of bathing depends on hair type, weather conditions, physical activity and, of course, by the profession. For a proper shampooing requires good wetting the hair with warm water. The shampoo is applied to the scalp and gently massage done with the fingertips, not nails, with moves that start from the top and go out. Here is a good rinsing.It is necessary to meet the shampoo to hair type (oily, dry or normal). The shampoo with protein and penetrate the hair, but they overlap, giving it shine. A protein shampoo acts as a shampoo and conditioner together. 

The hair perm, the straightened and dyed hair shampoos require low pH. Intense exfoliation may need shampooing with an Anti-Dandruff shampoo. Hair after shampooing can be rinsed with a cream or a conditioner or shampoo from the outset to use type "2 in 1". These products lubricate your hair and minimize the damage caused by combing or brushing. Products containing protein also strengthen the hair, but temporarily.The hair should be dry after shampooing with a light wiping with the towel, not rubbing, and if possible to afinontai to dry naturally in air. If it is necessary to use hair should be set at low intensity and the hair remains slightly damp. Combing and brushing while the hair is still wet causes more hair loss than simple extrication with the fingers. Combing or brushing should be done after they have dry hair. A styling gel or foam can give volume and thickness of hair. Does not affect default but can be seen drying, especially at their tips.

.Treatment of alopeciaIn androgennitiki alopecia, the trichikoi pockets, the action of androgens, gradually atrophy and disappear.Prevention can only be achieved by early treatment.Topical treatment. It is a therapeutic approach that uses minoxidil. Minoxidil is a medication applied directly to the hair. Reduces hair loss in 50% of men and women. Although the mode of action is unknown, it seems to lengthen the phase of regeneration and can increase blood flow to the hair follicle. The reappearance of hair is more pronounced at the top of the head than in front and not observed until at least 4 months. 

Patients respond better to treatment with minoxidil are those with recent-onset androgenic alopecia and small areas of hair loss.Research has shown that minoxidil is more effective in people who have experienced hair loss for less than 5 years. In general, women respond better to topical treatment with minoxidil compared with men. Stopping use can lead to hair loss that developed during its use. This drug was originally manufactured for the treatment of hypertension and showed a side effect of hair growth, often in undesirable areas. For the treatment of hair loss used in the form of lotions for topical application. Her hair is coming out is messy, treatment costs a lot and so far the results vary.

 In women, if pregnant, treatment should be postponed until after delivery.Antiandrogoniki treatment. It is effective only in men, in the form of finasteride by mouth. In women the results were disappointing, as the topical application. Finasteride is a pill taken once a day and blocks the action of testosterone on hair growth, but is antiandrogenic. Testosterone is a hormone found in higher concentrations in men. Although it is more effective in alopecia of the top of the head, has been shown to increase the regeneration and in the anterior region of the scalp. A small percentage of rough taking finasteride may experience a decrease in sexual desire and difficulty achieving an erection.Minoxidil and finasteride must be taken indefinitely to maintain the regenerated hair. If used, the physician must regularly monitor patients for possible side effects.

Like skin cells, hair hair grow and shed periodically. Usually our heads drop 50 to 100 hairs a day, therefore, to see a small amount of hair in the tub after bathing, it should cause great concern. The average rate of elongation of hair is about 1 cm per month. Each hair grows for 2 to 6 years and then resting. At any given time, approximately 85% of hairs are in growth phase and 15% in resting phase. After the rest period, the hair falls and a new beginning to grow in its place. Disruption of the 
physiology of this cycle leads to alopecia. Normally, the density of hair follicles is 100 / square centimeter. The thinning of the scalp starts to become noticeable at densities of less than 30 follicles / square centimeter.

Types of AlopeciaThe alopecia in terms of causes, not separated into oulotikou and oulotikou type. Most common representatives of the class is androgennitiki alopecia, alopecia areata and diffuse hair loss, due to several causes, including thyroid gland, iron deficiency, poor diet, stop taking oral contraceptives, retinoids (drugs against edge) or lesions in the hair. Hair loss can occur transiently after pregnancy. Sometimes there is a temporary hair loss when a substance or a disturbance causes a temporary problem. The second category, oulotikou alopecia is less common and can result in burns, bursitis and in autoimmune diseases such as discoid lupus erythematosus, the follicular lichen et al.The androgennitiki alopecia caused by the action of androgens, both men and women, which in combination with an inherited predisposition, causing atrophy of the follicles. It happens with different mechanisms between men and women.

On male hair loss, growth of hair and the intervals between stages of development are reduced. The periods of accelerated growth, but more and more roots fail to create new hair at the end of each cycle.The male alopecia is a type that characterizes the regions of the head that are most affected. It usually starts from the boundary of hair, which gradually subsides, forming a line like "M". It may also be the man to see a thinning of the hair dryer and they do not grow at the rate grew older. The hair on top of the head begin to thin, until the two peaks of the "M" to meet this point between them. Over the years it remains only an area around the head with hair that looks like a horseshoe.

The explanation for this form of alopecia is probably hereditary, which is complex and not well understood and seems to be associated with the response of hair follicles in normal secreted androgens, the male hormones, the secretion of which is controlled by the endocrine system. These hormones are essential for reproductive function but also for the distribution of body hair, both man and woman. The alopecia is also associated with increasing age.The prognosis for men is unknown. Some patients evolve to the point of complete loss of hair of the head.Others develop a localized dilution or not, keeping a large number of hairs. In any case, alopecia should be considered from the outset as a "normal" phenomenon, but should motivate the individual to seek dermatological advice, and may conceal more serious causes, or may be prevented if there is adequate timeinterventions.

Hair loss in women is frequent, longer than generally believed. For many years the alopecia was male issue and the discussions about alopecia in the woman was discharged as not socially acceptable topic. Was the exact opposite things increased, unwanted hair growth which was acceptable to men and women dismissed.Today however, the alopecia is recognized as a medical and aesthetic problem and a woman.It is common for women to have thinning hair as they grow up. To have a woman at the age of 80 years, the same hair you had at 18 is extremely unusual. The other end, however, extensive hair loss that leads to "visible" results, characterized as alopecia. The hair loss in women is however much less pronounced, compared with men. 

The complete loss of hair and the formation of 'bald' is relatively uncommon.It also differs significantly the distribution of loss in the early stages. Usually appears diffuse thinning the crown, but by keeping the edge of the hair in front, have normal density. Only at an advanced stage of hair on top may have fallen. So, ultimately only a small percentage of women will develop male pattern baldness.The alopecia in women does not usually abnormally high androgen levels, and here plays an important role heredity, related genes inherited from both our parents. But in all cases of hair loss in women is essential to an examination by a dermatologist, to see that hair loss is not the result of another medical problem.

Alopecia areata causes hair loss and otherThe gradual transient hair loss can come from a variety of causes, including excessive hair, tight hair, compulsive acts, or check (pulling, breaking, twisting the hair with your fingers), skin diseases or infections, systemic diseases (p . eg systemic lupus erythematosus), high fever, poor nutrition (chronic disease, strict dieting or anorexia), use of contraceptive drugs and medical treatments, such as chemotherapy.Sudden temporary hair loss due 
to the more commonly known as alopecia areata, a condition generally occurs in 2% of the population. The alopecia areata begins abruptly with the appearance of one or more circular "patches" in hair, 8 cm in diameter, which may overlap. These bald areas are soft and painless. The cause of alopecia areata is unknown. Possible responsible factors are stress, familial predisposition and autoimmune reactions against the hair follicles.In 90% of cases of alopecia areata hair reappear after a period of 6-24 months. The outcome is worse when the episode alopecia areata occurs early in life or if you lost all the hair on the scalp during an episode.For the diagnosis of alopecia areata, the doctor will take a complete medical history and perform a thorough physical examination. Further tests may be needed, if the incident occurs in the territory of another disorder.The treatment will depend on the treatment or control of an underlying disorder, if one exists. Your doctor may suggest various techniques for the reappearance of hair.
