Learn about the causes of the relatively rare condition known as scalp psoriasis.
Psoriasis can appear anywhere on the body. Here, we are talking about scalp psoriasis. The origin is always the same, regardless of the location.
The immune system sends signals to fight an infection (whether real or not).
As an immune response, the body releases inflammatory chemicals that accelerate the renewal of epidermal cells.
Generally, in an unaffected individual, skin cells renew every 21 to 28 days approximately. This natural process is invisible to the naked eye.
In the case of psoriasis, the process can be ten times faster, which creates patches consisting of clusters of dead cells on the skin's surface.
What causes flare-ups? Although the immune response causing psoriasis is well understood, the triggering mechanisms affecting the immune system of affected individuals are not well understood.
There is no cure for psoriasis, but in some cases, the disease goes into a long remission phase before reappearing.
Factors such as stress, epidermal injury, or hormonal changes can worsen the condition of those already suffering from it and, in some cases, cause a sudden flare-up of psoriasis.
