Deionized skin of the head
The scalp is protected by a thin hydro-lipid film composed of secretions of sweat and oil glands.
The presence of this protective layer and the correct ratio of mineral salts, water and lipids is the basis of living and healthy hair. Unfortunately, a variety of external and internal factors can affect the scalp, reducing the moisture content, leading to the problem of dehydration. This disorder manifests itself as an ecdysis, differing from dandruff in the size of “flakes” (they are much smaller).
The scalp, devoid of the protective hydrolipid layer, can not effectively protect itself from external influences, it becomes dry and easily irritated.
Dandruff – the problem of the scalp, which consists in an excessive portion of the separated dead keratin cells ( “CEREAL”) caused by physiological disorders in the body and activities of fungi of the genus PITYROSPORUM OVALE, is present on the scalp.
Dandruff looks like thin flakes of gray-white color, visible on the scalp and hair, easily detached from the scalp. The presence of dandruff suggests a variety of diseases of the scalp. The most common of these is seborrheic dermatitis. Dandruff, accompanied by itching, can be associated with a problem of increased fat content. Highlight fat and dry dandruff. In the first case, “flakes” are visible and retained on the scalp with the help of skin fat. This disorder is usually accompanied by itching and redness and often leads to hair loss. In the case of dry dandruff, the skin is dehydrated, so that dead cells easily separate and fall. This problem is more aesthetic than physiological, since it does not lead to the appearance of itching and hair loss. This type of dandruff refers to seasonal phenomena, is more pronounced in winter, weaker in summer. The impact of strong sun can improve or worsen the problem of dandruff, but similar reactions of the body are always individual and some laws do not obey. Stress is also an important cause of dandruff, because it can provoke deterioration of digestion, which often underlies this problem.
SEBORRHEA CONCLUDES IN THE EXTREME PRODUCTION OF THE SEBUM.
If seborrhea is associated with dandruff and the formation of yellowish fatty flakes, then this problem is called Pytiriasis steatoides. This type of cutaneous disorder often occurs as a result of the problem of sweating or hyperhidrosis.
Excessive production of sebum and hyperhidrosis can easily be confused. To understand what kind of problem this or that person encountered, we suggest using the simplest method of diagnosis. Put a piece of tissue paper on the open central part on the scalp. If the paper gets wet immediately, then there is the problem of excessive sweating. Otherwise we are dealing with seborrhea.
Seborrheic dermatitis is the most common problem in men under the age of 45 years. It is characterized by the presence on the scalp of yellowish fatty “flakes”, redness and intense itching.
SENSITIVE SKIN HEAD
Physical and psycho-emotional state, as well as chemical exposure may cause irritation and hypersensitivity of the scalp.
These factors can easily violate the hydrolyside film and lead to dryness, irritation, and peeling. When the balance is broken, fungi and microorganisms begin to multiply intensively, leading to itching and redness. In this case it is necessary to use soothing products to ensure the health of the skin.
Androgenetic HAIR LOSS – Often there are hereditary disease: it affects about 20% of men aged 20 years and 50% – over 50 years.
In women, this disorder is less common: only 10% are affected by it before the onset of menopause, and 40% – after. In both cases, the disorder increases with age.
Diagnosing problems in men is simple: as a rule, it manifests itself early – at the age of 30, as it is connected with the activity of male sex hormones, and progresses with age (dynamic gain all individually). Hair loss of this type develops gradually, initially expressed in the thinning of the hair, is often accompanied by seborrhea. Androgenetic alopecia (hair loss) leaves intact only the occipital, and temporal nizhnezatylochnuyu zone and progresses up until not lead to the classical koronovidnomu baldness. Unlike men, in women this problem manifests itself later, at the age of 30 to 40 years; The “horseshoe” zone is most affected by the negative effect and leads to progressive hair thinning along the central part and temporal zones.
The phenomenon of hair loss in the telogen phase – a reversible form of hair loss, lasts approximately 2 months and is caused by physical or psychological stress. Hair loss of this type occurs about 3 months after a stressful situation. This time is required for the hair bulb to thinner and leave the follicle.
