Hair Dye: Is there a risk of worsening scalp psoriasis?

Having scalp psoriasis does not mean that one should stop going to the hairdresser. The disease does not prevent the patient from living normally. Moreover, it does not imply a direct contraindication in this regard.

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 color their hair. These are less likely to cause allergic reactions 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. Here 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 hair care, 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 sensitizing the scalp. It is recommended to air-dry your hair.
