Statistics is a stubborn thing, in the matter of hair loss, the data indicates that 40% of men and only 1% of women suffer from progressive baldness. Temporary loss of curls density, which causes stress, hormonal and seasonal fluctuations in the body, affects 60% of the fair sex. Such disappointing data cause many to think about what provokes alopecia and how much hair grows on the head.
TELOGEN AND ANAGEN
The most common type of alopecia is transient, caused by external and internal factors. The elimination of the cause leads to the resumption of hair growth. There are two types of temporary alopecia – Anagen and Telogen effluvium. How much hair grows in a day depends on genetics, lifestyle and the presence of body malfunctions. It is not difficult to diagnose one form or another; for this purpose, the method of rapid extraction of 50 hairs and dyeing their bulbs in DACA (4-dimethyl-aminocinnamaldehyde) is used.
This dye reacts with citrine, located in the inner sheath of the hair root. In the telogen phase, hairs have non-pigmented bulbs that do not have an inner shell, so they do not change color under the action of DACA. The anagen phase is characterized by the presence of elongated pigmented bulbs, which are colored DACA in a saturated red color.
Under this concept understand hair loss that occurs in the phase of telogen. The main reasons should be sought in emotional and physical overload and stress. Surgical interventions, weight loss, failures at work or in personal life provoke a stop of hair growth, which for a long time should have been in the active stage. These hair follicles go to the stage of catagen, and then telogen.
Hair loss at the telogen stage in most cases is associated with physical and emotional stress. Follicles simultaneously discard hairs, after which a new life cycle is launched, the duration of which can be shortened or normal, depending on the presence of the cause of alopecia. In this situation, it will not be difficult to grow hair on your head, it is enough to eliminate the cause. With Telogen effluvium, hair thinning can occur 3-6 months after the stress experienced, therefore hair loss is rarely associated with events in life.
Telogen effluvium forms A special form of Telogen is a fallout associated with having a baby or ending a pregnancy. In the first case, the follicles remain in the anagen phase and do not go to the catagen stage. During pregnancy, women are not interested in growing hair, because the curls themselves become thick and long. A separate category of “victims” of alopecia – young mothers whose body does not receive the necessary amount of vitamins and good rest.
But soon after birth, the hormones stop their activity and a significant part of the hair, which should have fallen out during the period of pregnancy, falls out immediately. This happens during the period when the baby turns 3-4 months, besides, the situation is aggravated by chronic fatigue, stress, and anemia. Long-term use of hormonal contraceptives makes its own adjustments to the body’s work. Often, their cancellation is accompanied by temporary alopecia.
The rarest form is prolapse associated with follicular transplantation. It would seem that such operations are aimed at combating alopecia, but in the new place the follicles are experiencing severe stress and stop growing. The first 3-4 months after transplantation, hair can actively fall out, only six months later, the situation normalizes.
There are also a number of diseases associated with temporary hair loss:
Secondary syphilis Alopecia occurs in some areas. The location of the lesion resembles a trail left by a mole after regaling with a woolen cloth.
Scleroderma A disease characterized by the excessive production of collagen. It would seem that collagen is the building protein of the hair shaft and should strengthen the curls. However, its overabundance leads to thickening and thickening of the skin. Follicles are compressed. There is a violation of the blood supply, resulting in increased prolapse.
Ringworm The disease causes a special type of fungus. Hair breaks off so close to the root that it seems as if they fell out.
ANAGEN EFFLUVIUM Under this term understand the sudden hair loss that occurs under the action of radiation or chemical agents. Unlike telogen alopecia, follicles do not enter the telogen stage. Signs of external exposure occur in 1-3 weeks.
Most often, this type of alopecia occurs after chemotherapy aimed at treating cancer tumors. Less commonly, the cause is thallium and arsenic poisoning. Chemotherapy leads to hair loss (full or partial) in 90% of cases, but it is important to remember that the price of not using the treatment is your health, and the curls are sure to grow. Alopecia is inevitable when using drugs: Taxol, Adriamycin, Amsacrine Epirubicin and Cytosine Arabinoside Ifosfamide.
TYPES OF ALOPECIA
Hair grows or does not grow after falling out, depends on the type of lesion and the state of the follicle. Congenital alopecia. An extremely rare disease, which is manifested not only by the complete absence of hair but also by the degeneration of teeth and nails. Due to the fact that the pathology is genetic and is associated with a violation of the synthesis of amino acids, to restore hair is not possible.
Transplantation is considered the only effective method.
Pediatric alopecia is often accompanied by dystrophy of the teeth and nails. Premature alopecia. In scientific circles, premature alopecia is called presenile or androgenic. It is this type of baldness that is diagnosed in 95% of men who are perplexed by early hair loss.
The main cause of the disease is hormonal disorders, in which the active form of the male hormone testosterone, dihydrotestosterone, has a damaging effect on the follicle.
You can fight for hair density with drug therapy and low-intensity laser radiation. If after half a year the procedures have failed, hair transplantation is applied.
Instructions for combating premature baldness recommends the use of plasma-lifting and mesotherapy Seborrheic alopecia. This type of hair loss is directly related to seborrhea – a painful condition of the skin, which is caused by excessive sebum secretion. Causes should be sought in disorders of the neuroendocrine regulation of the sebaceous glands.
Diffuse thinning over the entire scalp is accompanied by peeling and reddening of the skin, itching and increased fat content. A small amount of dandruff may be the beginning of seborrheic dermatitis. Symptomatic alopecia . Hair loss, which is not a separate disease, but only accompanies the course of such diseases as syphilis or large-scale deficiency of vitamins. It has a focal (cicatricial), total or diffuse nature. Hair restoration occurs after the exclusion of the cause and the general strengthening therapy. Cicatricial alopecia . Occurs at the site of scarring skin changes. The cause of such changes is most often found in viral and bacterial infections, which lead to the formation of connective tissue on the skin. Chemical, thermal burns, and physical injuries also contribute to cicatricial alopecia. A common feature of various forms of cicatricial alopecia is irreversible damage to the follicles. Not long ago, trichologists cited statistics in which they indicated the proportion of cicatricial alopecia at the level of 1-2%, today these figures have risen to 9%. Treatment of the formed cicatricial alopecia is carried out by the only method – hair transplantation. Focal (gnezdny) alopecia. The disease is characterized by thinning hair in several areas of the scalp, as well as a beard, eyebrows, and eyelashes. Unfortunately, the causes of this phenomenon cannot be established. Doctors associate it with toxic, infectious and endocrine factors. Focal (alopecia) alopecia – the most difficult to diagnose a type of baldness The development of the disease begins with small foci, which, as they grow, merge into a single area devoid of hair. Inside the foci remain small “hemp” with a thinned top and a swollen root. In children, alopecia manifests itself in the form of small focal “gaps” or an elongated corolla that extends between the nape and the auricles. Often, the disease reaches the stage of total malignant alopecia, which is characterized by loss of soft hair all over the subject, eyebrows, and eyelashes.
Treatment of the disease is carried out in a hospital or on an outpatient basis, using vitamin therapy, photochemotherapy, UV radiation, physiotherapy. Cryotherapy with chloroethyl and carbonic acid snow and massage with an electric brush showed high efficiency. As a preventive measure, mesotherapy sessions with cocktails containing collagen and elastin are recommended.
Now you can rightly call yourself a guru of healthy and thick curls, you know if hair grows out if they are pulled out and what provokes alopecia, how to prevent hair loss and why it is important to maintain inner calm.
