Scalp psoriasis and eczema of the scalp are two conditions that affect the same area and share similar symptoms.
Eczema of the scalp causes inflammation of the skin. Typically, the condition will cause the scalp to feel itchy and sore, which will lead to dry skin developing on the scalp. In more severe cases, eczema of the scalp can cause blistering and weeping lesions to form. For a lot of sufferers, the condition will usually go through periods of being mild to non-existent, which will be followed by periods where the symptoms will flare-up.
Eczema of the scalp can have a variety of triggers, the most common being:
Irritants, such as shampoos and haircare products
The environment-specifically cold or dry weather
Psoriasis of the scalp usually develops in patches. It presents as red, flaky areas of skin that are covered with grey/silvery scales. The severity of these symptoms will vary from person to person.
For some, the condition will only cause mild and infrequent irritation. For others, scalp psoriasis can be far more frequent and severe. Scalp psoriasis is caused by the body producing too many skin cells. The normal rate of skin cell renewal is between 3-4 weeks. For a psoriasis sufferer, this process happens a lot quicker (3-7 days). This causes the build-up of skin cells that psoriasis sufferer’s experience.
