Psoriasis is a chronic, inflammatory disease which can affect the skin, joints and nails. The causes of psoriasis are not fully understood and are the subject of ongoing research. In psoriasis, the immune system is mistakenly activated, which leads to overproduction of skin cells. Skin cells build up too rapidly on the surface of the skin, forming raised, red, scaly patches (called plaques). These plaques are often itchy and sometimes painful. Psoriasis lesions commonly appear on the scalp, limbs and lower back, but they can occur anywhere on the body.
Some people are not very affected by their psoriasis symptoms, but for others, psoriasis is a disabling and embarrassing condition that affects their lifestyle and their interactions with others.
There are many treatment options which can help control psoriasis and offer significant relief of its symptoms.
Psoriasis treatments aim to:
- Interrupt the cycle that causes an increased production of skin cells. This reduces inflammation and plaque formation
- Remove scales and smooth the skin
Types of Treatment
Treatments for scalp psoriasis can be divided into 3 main types:
- Topical treatments (creams, foams, lotions or ointments applied to the skin)
- Light (photo) Therapies
- Systemic therapies (taken by pill or injection)
