This inflammatory skin disease is aggravated, among other things, by stress, certain medications, friction and scratching.
Depending on the discomfort and symptoms, the dermatologist often prescribes topical corticosteroids and/or vitamin D derivatives in the form of shampoo, lotion, or mousse. Medication (immunoregulators, biotherapy), also make it possible to relieve severe forms of psoriasis. In addition to this basic treatment, a soothing treatment is used. This contains antifungal active ingredients, which block the proliferation of Malassezia (a fungus that can promote the persistence of psoriasis), and soothing actives to calm itching.
But in parallel with these treatments, it is advisable toadopt good hygiene practices on a daily basis in order to limit irritation and live with your psoriasis without (too much) disrupting your habits. Dr. Philippe Assouly, dermatologist specializing in the scalp, enlightens us.
How to recognize scalp psoriasis?

It manifests as lesions in the form of whitish patches, dry and dander which fall on the shoulders, accompanied by more or less intense itching.
What shampoos to use for psoriasis?
Better to opt for a mild shampoo bought in pharmacy or drugstore. Their washing bases are not the same as in supermarkets: they foam less, but they irritate the scalp less. Gold, local irritation may be enough to restart the psoriasis process and cause a flare-up.
Avoid hot water which increases vasodilation, worsens inflammation and causes itching.
How often should you wash your hair?
Washing your hair daily, if needed, is fine, as long as you use a non-irritating shampoo.
Do not overuse scalp scrubs that attack the skin, prefer masks based on oils or containing urea to take off the scabs without tearing them off. In this case, after the mask, apply the shampoo and emulsify before putting in water, otherwise, there is a chemical reaction and the fatty substance is hard to remove.
Can we use a hairdryer?
The idea is to let the hair air dry, because heat can be a source of irritation. If you really want to, you can still use a hairdryer, making sure to stay in the cold breath position and about 20 cm from the scalp.
In contrast, better not to go out with damp hair under a cap or hat, to prevent maceration of the scalp which promotes psoriasis.
How to avoid scratching?
It’s a vicious circle : 10 minutes of scratching lengthens the duration of the scales by two to three weeks. It is therefore essential to try not to scratch yourself.
Unfortunately, there is no miracle trick: everyone to find their solution, for example by spraying cool thermal water, by shampooing gently when the temptation is too strong, or by massaging yourself with your fingertips with a soothing cream, to keep in your bag.
If the scratching becomes a tic, as an alternative, it is necessary scratch something else, for example, his pants or any fabric: it works! Can also put local treatments in the fridge because the cold relieves the itching.
How to style your hair?
The goal is always to limit irritation to the scalp. It is, therefore, necessary to comb your hair with a brush with soft spikes and round ends, without pressing too much on the head. If you want to tie your hair, do not pull on the scalp: beware of ponytails, updos, or too-tight braids.
The hair itself is normal, only the scalp is affected, so you can do whatever you want on the lengths: hairspray, spray …
Finally, it is necessary to avoid anything that “suffocates” the scalp, headband, hat or hat type, especially if it’s hot.
Can we do coloring?
Nothing prohibits making a color, even permanent (discoloration), provided you carry out the use test verifying that you do not react to potentially irritating chemicals contained in the formula. To do this, apply a little product behind the ear and check, 48 hours later, that the skin does not show any redness.
In addition, it is preferable to avoid periods of outbreaks so as not to attack the already sensitized scalp. Vegetable coloring without chemical substances (Logona, Martine Mahé or Terre de Couleur, in organic stores), less allergenic, have less risk of triggering an outbreak of psoriasis.
Should I report it to the hairdresser?
Yes, this already helps to defuse received ideas, by specifying that it is not contagious. Then, ask him not to use potentially irritating products, such as hairspray.
For the same reason, better refuse certain proposed treatments, like brushing, which heats and pulls on the scalp. And to be safe, nothing prevents you from taking your own shampoo, hairdressers are used to it.
