Hair Dye: Is there a risk of exacerbating one's scalp psoriasis?

Having scalp psoriasis does not mean that one should stop visiting the hairdresser. The condition does not prevent the patient from living a normal life. Moreover, it does not directly contraindicate this either.

Hair dyeing is not prohibited in cases of scalp psoriasis. This skin eruption is partly due to genetic inheritance. However, it is recommended not to dye hair during a flare-up because the scalp is fragile, and to limit its application on the hair while avoiding the epidermis.

The use of chemical hair dyes should be avoided as they may exacerbate this condition. This type of dye sometimes contains toxic agents, such as ammonia, which are responsible for allergies and skin reactions that promote the onset of psoriasis outbreaks. Instead, a person suffering from scalp psoriasis can turn to plant-based dyes that do not contain chemical substances if they wish to colour their hair. These are less likely to cause allergies and reduce the risk of psoriasis flare-ups.

No scientific study has been conducted to observe the effect of hair dye on scalp psoriasis. Generally, we advise you to seek the opinion of your hairdresser beforehand, who will guide you on the best course of action.

To better care for the hair, even if the scalp suffers from psoriasis, certain practices can be adopted. Below are the recommended practices:

• The use of gentle shampoos, whether at home or at the hairdresser's;

• The use of a hairbrush suitable for a scalp suffering from psoriasis;

• For haircare, avoid wearing items that can suffocate the scalp such as hats, beanies or headbands, especially in hot weather;

• When using a hairdryer, ensure to keep it at a distance of 20 cm from the scalp to prevent further sensitising the scalp. It is recommended to allow your hair to air dry.
