The scalp is renewed by removing dead cells and freeing up space for new growth. This process occurs once a month. As a result, peeling of the scalp and dandruff may occur. Dandruff may be yellowish, oily, surrounded by patches of reddened skin. Consider, a sign of a disease is a crust on the head in an adult.
Reasons for the formation of a crust on the head
Cork, gneiss, lep - whatever you call it, and the appearance of the head will not make it any better. In most cases, the dry crust on the head in an adult is the result of external exposure. In other words, this symptom means an allergic reaction to pathogenic or aggressive chemical agents that cause increased sensitivity of the scalp. These include:
- various shampoos, lotions;
- hair spray;
- hair dye;
- styling gels.
Occasionally, prolonged exposure to heat or, for example, dry, heated air can lead to the appearance of a crust on the scalp.
One of the factors of dandruff formation on the scalp in an adult can be acidification of the body, which occurs as a result of overloading the digestive system, which prevents the removal of metabolic waste through the skin. Another cause of an adult's crust on the head is allergy to certain foods.
In addition, a yellowish-white crust on the head in an adult can be a symptom of skin lesions as a result of a disease such as seborrheic dermatitis. Of all the above, such skin pathology is considered the most serious.
What is seborrheic dermatitis? Causes and symptoms of the disease
This is one of the harmless and non-contagious skin diseases. The causes of seborrheic dermatitis are not yet known. It is assumed that a fungus that over-colonizes the scalp plays a certain role. The body reacts to this increased inflammatory response. Experts also believe that the composition of sebum changes. This disease in adults is the most common cause of dandruff.
Another possible cause of this disease can be increased activity of the sebaceous glands and congenital predisposition. Decisive factors also have the male sex hormones androgens. This is confirmed, firstly, by the fact that modeling in children usually disappears at the age of three or four months, that is, at the time when there is a natural decrease in the levels of certain male hormones in the child’s body. Secondly, the gneiss crust on the head in adult men or women mainly appears in menopause.
As a rule, people with oily hair and skin are more susceptible to seborrheic dermatitis. Some patients also note a significant impact of stress and climate, for example, an increase in air temperature in the summer, being in the mountains or at sea.
How to recognize the disease
Seborrheic dermatitis manifests itself in the form of whitish-yellow scales on the skin surface, which often look oily. The skin under the crust is red and inflamed. In some patients, the disease is accompanied by itching on the affected skin. Scales form especially on the scalp, but can also be on the face.
In ten percent of cases, seborrheic dermatitis is not limited to the scalp. Eyebrows, nasolabial folds on both sides of the mouth and the beard area are particularly susceptible. Sometimes scales are also formed in the middle of the sternum and in other parts of the body - in the groin, axillary folds or the genital area.
If there is a suspicion of seborrheic dermatitis, the dermatologist will first of all examine the affected skin. With typical symptoms, the diagnosis is usually confirmed. Nevertheless, dandruff and flake formation can also cause other skin diseases:
- shingles or tinea versicolor.
In order to distinguish the disease, a dermatologist can take a dandruff scraping, but in case of doubt - a deeper sample of skin tissue for histological examination.
Treatment and possible complications
Patients who suffer from seborrheic dermatitis tend to experience long-term treatment:
- If the scalp on the scalp is caused by aggressive chemical care, the abandonment of these cosmetics can promote healing.
- Other methods of treating the crusts on the head in adults are mainly designed to gently and gently relieve the itching, remove the dried out cells and restore the necessary moisture.
In parallel with the therapy, you can try home remedies, such as wheat bran trays. Many dermatologists advise before sleeping to rub the affected areas of olive or baby oil. The next morning, the hair should be washed with baby shampoo, then you can remove the softened gneiss with a soft brush or sponge. It is important not to use anti-dandruff shampoo, as this may cause skin irritation.
Do not try to comb a dry crust without soaking before, to avoid scratches and scars on the surface of the skin. If your head itches after removing dandruff, use soothing compresses from soaked tea leaves.
For severe inflammation, Cortisone cream is often recommended in combination with antifungal agents. High-fat ointments, such as petrolatum, should be avoided.
What complications can occur?
As a result of skin lesions with seborrheic dermatitis, infections caused by fungi or bacteria can develop, which are accompanied by very strong inflammations and even a significant increase in body temperature. In very rare cases there is redness and peeling of the whole body - the so-called erythroderma.
As you can see, the appearance of a dry crust on an adult’s head may have various causes. To rule out serious diseases, you should consult with your doctor.
