Even if we do not know why certain types of hair are predestined, effective treatments exist.
Causes and consequences of dandruff
With our partner Clauderer Center , we will better understand this phenomenon that affects many men and too often very unpleasant.
In short: Films such as itching that often accompany them, correspond to abnormal activation of the scalp skin cells and their expulsion by desquamation (removal of surface layers of the epidermis in the form of small plates or scales).
This anomaly remains a mystery. If we now know what causes dandruff and what favors them, we still do not know why some are predestined hair and others do not.
However, today there are effective ways to treat them. Is not this the most important?
What causes dandruff and itching?
Dandruff is caused by a microscopic organism, the pytiriasis. This fungus is present on all scalps, remains generally inactive. Why is it taking to proliferate on some heads? Researchers do not yet have a definitive answer. Some speak of genetic predisposition, some of the acidity of Ph scalp trigger its expansion.
What normally happens
Normally, the skin of the scalp, like that of our whole body is renewed once a month.The new cells form in the deep layers of the dermis and eliminate those who died, pushing them outside the skin. This is done without us take care, change occurs slowly and non-synchronous, unlike some of molting animals.
What happens with pytiriasis
When the fungus begins to colonize the scalp, while the local ecosystem breaks down. Under his leadership, the cellular traffic is accelerating, new cells are formed too quickly (in two weeks, or eight), they leave no time for dead cells to dissolve imperceptibly, forcing them to clump together other and accumulate on the surface of the scalp in the form of dander.
Pytiriasis and sebum
The pytiriasis eats fatty acids that will naturally look in the sebum secreted by sebaceous glands. Does this mean that flourishes only on the scalp fat? He prefers but can also grow on dry leather, capturing the little fat in it and making the field (and hence the hair) even drier.
In both cases, the pytiriasis turn generates derived acids that irritate the scalp (hence the itching). In these irritations, the body reacts by speeding up the process further cellular and film formation, the circle is vicious.
The different kinds of films
The dry films, the most common
They detach spontaneously and snow fall on the clothes. They appear more readily on normal or dry scalp.
In this category, some films are not due to pytiriasis but just a dry scalp too, including a chronic lack of sebum “crack” the skin, as a land that lacks water. So, for example, scalp hair afros.
At diagnosis, a specialist can make the difference with the film due to pytiriasis: the scales are smaller and do not look the same.This is important because this type of dandruff, dandruff classics have no effect.
The disorder is almost always accompanied by itching and the treatment is to hydrate the scalp.
It is also often the case with scalp treated with minoxidil. Containing a high percentage of alcohol, this fall can cause inflammation of skin cells with dry films and / or itching (pruritus). It must then apply a moisturizing milk and healing to rebalance the scalp.
Oily dandruff
More insidious, they manifest themselves on greasy scalps and remain stuck on the head, sclerosis. These plates, stuck in seborrhea, promote the formation of bacteria and often cause irritation and severe itching.
The pytiriasis sometimes resulted in seborrheic dermatitis, with redness and oily dandruff stuck, raised eyebrows to the forehead or, more rarely to the nostrils and chin. Ass to be confused with psoriasis of the scalp, a condition much more disabling. If in doubt, only a biopsy can make a difference.
Dandruff and hair loss
Warning! The idea that the film prevents the roots to breathe and blocked the development of the hair is wrong. The film, they stand or remain stuck, can be symptoms parallel to hair loss, they do not fire. If your hair falls too much, we must look elsewhere for the cause and make a thorough diagnosis of the hair.
Which promotes the appearance of dandruff
The factors are highly variable and often accumulate each other.

Recommendations and what to avoid
A + dandruff treatment
which contains at least one of the following active ingredients:
| Antifungal | : | Reduces the number of fungi (zinc pyrithione, selenium sulfide). |
| Anti-proliferative | : | Does not act directly on the destruction of the fungus but slows the abnormal production of skin cells (coal tar). |
| Keratolytic | : | Breaks down the intercellular bonds, so that dead cells that reach outside the scalp and no longer have separate blocs in squamous (sulfur, salicylic acid). |
Note: All these products treat the symptom but can not eradicate the pytiriasis. It is still likely to reactivate, as a result of internal or external factor. For dosage, it is best to follow the instructions of the laboratory, during periods of crisis.
+ Before you shampoo, lotion , made from essential oils and plant sanitizing hair, to soothe the itching, scalp clean and rid of its microbial flora, if necessary.
+ An improved hygiene during periods of crisis . If pytiriasis is not contagious from one person to another, however, it is often preferable to wash your brush or comb your because you can re-infect you with them.
+ The consumption of fresh fruit , before or between meals to avoid gastric fermentation.Green vegetables (potatoes or steamed), at least once a day to make your diet less acidic.

| + | The regular use of anti-dandruff shampoos . Most are effective against pytiriasis provided to choose from depending on the nature of his films (dry or oily). But they are to be consumed in moderation. Abuse of these shampoos may have the opposite effect to that intended: they can irritate the skin and devitalized hair. |
| + | The gels, the foam or the spray containing alcohol : they dry out and irritate the skin. |
| + | The foods that tend to acidify the pH of the skin: too much coffee, sweets, dairy products or red meat, deli … |
