Casper (Pityriasis capitis) is the formation of excessive or flakes of dead skin scabs formed on the scalp. While it is normal for skin cells die and forming flakes, some people, either chronically or as a result of certain conditions, are experiencing an abnormal amount thereof, which is usually accompanied by redness and irritation. Most cases can be treated with a shampoo or specialized home remedies.
The dander can also be a symptom of seborrhea, psoriasis, fungal infections or lice. It is advisable to avoid scratching excessively. Scratching to break the skin may increase the risk of infections, including Staphylococcus aureus and Streptococo. Despite the fact that these infections are at greatest risk of dandruff, many people treat it only because it can cause social problems or self-esteem.
As it grows skin, the epidermal cells are pushed outward where eventually die and fall as flakes of the head. In most people, these flakes are too small to be visible. However, certain conditions can cause the pace of change in the cells is unusually fast, being particularly common on the scalp. In people with dandruff, skin cells may die and be replaced about once every two weeks, as opposed to people without dandruff who takes about a month. The result is that dead cells fall into large blocks that appear as small pieces or grayish spots on the scalp.
Dander is understood as the result of a combination of factors. Of these, only a few have been investigated in depth.
The most common cause of dandruff is a fungus FM (previously known as Pityrosporum ovale). This fungus is found naturally in the skin surface of both healthy people and those with dandruff. The fungus human fat metabolism, resulting in a product that is antigenic. Thus, dermatitis in the area where the sébum, areas with several sebaceous glands (the scalp, face and upper body). When the Malassezia furfur grows too fast, the natural renewal of the affected cells and appears itching. Other fungi may have similar roles in the cause of dandruff, as well as certain bacteria.
The dander, in fact, it is not caused by the dryness of the scalp.
The mansa dandruff can be caused by sebaceous glands sobrerreactivas. Other causative factors include family history, allergies to food, excessive perspiration, the use of alkaline soaps, mycosis, and stress. Even the season can contribute to the problem: cold winters and dry are notorious for bringing dandruff or make it worse. The symptoms of dandruff can also be aggravated by exposure to dust, UV light, too strong shampoos and hair dyes. In some exceptional cases, dandruff can be caused by excessive use of gel or spray fixative.
The drug of choice now is Nizoral (ketoconazole), while coke and other less expensive shampoos can be chosen as the first attempt against the most tame. Coke has been increasingly promoted in the United States because of their suspected carcinogenic properties.
The dander can be a symptom of seborrhea. Joseph Bark stresses that "The redness and itching is actually seborrehica dermatitis, and often occurs near the union of the nose and eyebrows area, not only on the scalp." Injuries dry, thick and well-defined consisting of large flakes and silver aspect may be associated with psoriasis of the scalp less common.
Seasonal changes, stress and certain diseases also appear to affect the seborrhea. The cold, dry air of autumn and winter often triggers a relapse. The emotional stress can also worsen conditions.
The simple dandruff does not cause hair loss.
Dander can be linked in some cases with poor nutrition, particularly zinc deficiencies. Zinc can be found in foods like oysters, turkey, pork and some types of nuts.
The recommended daily intake of zinc is around 10 mg lower for babies, children and adolescents (by their lower body weight) and slightly higher for pregnant and breastfeeding women.
The appearance of the flakes can be reduced, especially those suffering from meek cases of dandruff, through the proper personal care. Some people avoid mistakenly washed their hair, believing that the effect of resect worsen their dandruff shampoo. However, to wash their hair regularly, in fact dead skin is removed before it can accumulate in larger flakes and remarkable. The use of acid based shampoos helps restore acidity to the scalp, decomposing oils and preventing dead skin cells accumulate in heaps visible. However, shampoos with a medication or more mansa shampoos unmarked to treat seborrhea may have little or no effect on redness and irritation.
The FOM severe dandruff, particularly if they are accompanied by the formation of flakes or scales in other parts of the body should be treated by a dermatologist. Dander can occur in conjunction with skin conditions such as psoriasis and seborrhea.
Dander varies from one person to another. It may be necessary to try several shampoos with different active ingredients (selenium sulphide, tar, salicylic acid, zinc pyrithione, ketoconazole) to find the most appropriate for each particular individual. In addition, an individual may find that switch between different treatments is more effective than attachment to a single trading system, which can become less effective as time goes on.
It has been found that the activity of elimination of fungi that have oil leaves of a tea tree (Melaleuca alternifolia) is useful in treating dandruff and this should be used while water thrown in his hair.
