The correct measures to alleviate scalp psoriasis.

Psoriasis on the scalp is very common. It is the most affected area by psoriasis in both children and adults. Indeed, it is estimated that 80% of patients suffering from psoriasis develop scalp psoriasis.

Generally, psoriasis plaques on the scalp are distributed in an asymmetricalmanner. They are observed along the hairline, at the back of the neck, and behind the ears, forming a sort of band around the head. The involvement of the entire scalp is much less common. According to studies, up to 70% of patients also complain of itching.

Psoriasis lesions on the scalp being highly visible, they can be a source of stigmatisation and rejection. The itching can significantly impair the quality of life of those affected by disrupting social interactions or sleep. Moreover, scratching worsens psoriasis lesions.

  If your psoriasis plaques are located on the forehead, behind the ears or on the nape of the neck, do not hesitate to use a emollient balm in order to reduce the scales. Ultimately, it is strongly advised against using heating devices that can damage the scalp. Opt for drying with warm air or air drying.

Originating from underground sources, thermal waters are naturally enriched with minerals and trace elements, allowing for therapeutic use. They possess healing, restorative and soothing properties. Therefore, the use of thermal water can help to alleviate itching. Spray the thermal water generously on your scalp to benefit from its soothing properties. For optimal effectiveness, keep your thermal water in the refrigerator.
