It may seem to you that you have an unending dandruff problem and that your scalp is sensitive literally to everything, this could be a sign of a more serious condition. It involves your scalp developing white-like patches that look like eczema.
According to the Cleveland Clinic, this condition is called scalp psoriasis, which is a chronic autoimmune disease causing rapid skin cell reproduction, resulting in thick, discoloured patches on the scalp, hairline, forehead, neck, and ears.
The above clinic further explains that “The plaques can be itchy or painful. Scalp psoriasis can cause hair loss (alopecia), and scratching your plaques may worsen that hair loss.”
When explaining the distinction between dandruff and scalp psoriasis, the National Psoriasis Foundation states that dandruff is a mild scalp issue with white flakes and dryness, managed with shampoos. Psoriasis, on the other hand, is said to be an immune-mediated disease causing the overproduction of skin cells, affecting the scalp. “Psoriasis is a chronic disease and is more severe than dandruff, often requiring medical attention and specific treatments.”
The Very Well Health publication mentions how this condition manifests its self is through:
- Small red bumps forming scales
- Scalp lesions and flakes
- Thick red or white plaques covered in silvery-coloured scales
- Itching often tearing scales off
- Extensive hair loss.
The Cleveland Clinic mentions that your skin cells develop too quickly as a result of inflammation brought on by your immune system’s overreaction. It is stated that new skin cells usually begin to proliferate every 28 to 30 days. “But in people with scalp psoriasis, new skin cells grow and move to the skin surface every three to four days. The buildup of new cells replacing old cells creates thick patches of skin.”
The causes of scalp psoriasis according to Cleveland are varied and can run in families. “Scalp psoriasis can run in families, but the actual triggers are complex. Parents may pass it down to their children, and environmental exposures can include skin trauma, sunburn, medications, stress and other inflammatory or autoimmune health conditions.”
Very Well Health suggests that for mild cases of scalp psoriasis, one can be treated with over-the-counter medicated shampoos and prescription corticosteroids. Severe cases are stated to require systemic medications like methotrexate, which suppresses the overactive immune system, reducing inflammation and reducing symptoms.
