What is psoriasis?
Psoriasis is a chronic inflammatory skin disease. It affects the superficial layers of the epidermis and the mucous membranes (genital region). On the body, it can appear as small lesions in the form of reddish spots.
These lesions are usually the size of a coin. We then talk about gout psoriasis. However, the most common form is plaque psoriasis (80% of cases). As its name suggests, it forms more or less large plaques.
Scalp psoriasis affects the scalp, skull. It can also be located at the edge of the front.
Hair psoriasis: gout or plaque psoriasis?
In the case of hair psoriasis, or scalp psoriasis, the form of the disease is plaque psoriasis. It affects the epidermis and therefore the scalp. It appears in the form of red patches. But it can also cause, more or less directly, a hair loss. It can lead toalopecia.
In the French population, there are officially between 2 and 5% of people suffering from psoriasis. 50% of them develop scalp psoriasis. Its occurrence is therefore frequent.
What causes scalp psoriasis?
Hair psoriasis has the same causes as all forms of psoriasis. A particular configuration of a certain cluster of genes leads to being able to potentially develop the disease. The immune system is more sensitive.
The factors generating a psoriasis flare-up are most often linked to stress or emotional shock. The psychological dimension of psoriasis is therefore important. However, psoriasis is a autoimmune disease. It is also frequently activated by a repeated rubbing. Aggression of the skin by chemicals can also be a risk factor.
Clearly, any source of irritation can cause an attack of psoriasis. The skin interprets friction as aggression. She defends herself. The cells of the epidermis are then in overproduction. The rate of cell renewal becomes 4 to 5 times faster than normal. Skin cells renew themselves in 4-5 days instead of the usual 28 days.
Psoriasis affects men and women equally. The disease does not no gender distinction.

Dandruff or psoriasis?
In itself, in cases of psoriasis, the scales come off and indeed form white or even yellowish dandruff. But psoriasis is not the only skin condition possibly responsible for dandruff. Science is still struggling to elucidate the origin of certain dandruff not linked to psoriasis. Their appearance is always the same, but the causes may be different. In all cases, this dandruff causes discomfort, linked to the way others look at it.
In case of dry dandruff, we speak of pityriasis simplex or pityriasis sicca.

It must then be linked to dermatitis or seborrheic dermatitis. In this specific case, it is often noted that other areas of the body are also affected by this dermatological problem.

To ensure an accurate diagnosis, it is best to make an appointment with your general practitioner, or even at a dermatologist. Depending on the type of skin condition, remedies or prescribed medications may vary.
Scalp irritation, possible causes
As mentioned above, psoriasis can be triggered by psychological reasons of stress, whether consciously felt or not. But a number of causes are linked to irritation of a sensitive scalp. This is why it is appropriate to carry out certain checks which can lead to eliminating the causes of a flare-up.
Irritation caused by pulling hair, ponytails
A hairstyle can cause damage to the scalp, for example when the hair is pulled too much. Making a ponytail or a bun can cause an attack on the scalp which turns into a skin reaction.
A scalp attacked by hard-bristled brushes or the effect of combs
Handling brushes with hard bristles or combs with aggressive teeth can lead to an inflamed effect on the scalp. It is advisable to act gently in the event of scalp fragility.
Drying hair, tips for psoriasis

On the other hand, the use of a hairdryer should not be banned, however it is better to respect a few simple rules. First, hold the hair dryer about twenty centimeters from the scalp. Then, adjust it to a reasonable heat intensity to avoid attacking the epidermis.
Air drying your hair can look very natural. However, it is a source of hair dehydration. The hair scales remain open longer and therefore dry out.
Are scalp psoriasis and facial psoriasis linked?
Scalp psoriasis is most often localized:
– at the top of the neck
– at the edge of the forehead and hair
– behind the ears.
It is therefore common to equate psoriasis of the hair with psoriasis of the face. In addition, in cases of psoriasis or seborrheic dermatitis, it is common for the wings of the nose to also be affected. However, it would be wrong to systematically equate psoriasis of the scalp with psoriasis of the face. The correlation is far from systematic.
Is psoriasis contagious?
Psoriasis often provokes a reaction of disgust or even repulsion in some people. Indeed, this spontaneous rejection often comes from the false belief that psoriasis is contagious. It is in no way contagious. It is not caused by any virus. On the contrary, as we saw above, it is linked to a genetic predisposition and to stress in particular. There is therefore logically no risk of contagion. The association France Psoriasis also puts a lot of energy into combating this cliché.
Hair psoriasis and hand psoriasis, a connection?
Strictly speaking, psoriasis cannot contaminate another area of the body by contact. Remember, the triggering factors for psoriasis are stress or psychological shock. Additionally, friction or irritation of the skin following contact with an irritating chemical are possible causes.
Thus, the only connection between the hand and hair psoriasis would be a report of aggression... If the hand scratches the itching linked to psoriasis, then its action will accentuate the irritation on the scalp. It can even cause lesions that will cause the skin to react. Scratching is one of the most harmful actions for scalp psoriasis.
Psoriasis on the fingers
