Causes and Risk Factors for Scalp Psoriasis
It is still unknown what exactly causes scalp psoriasis. Scientists think that the condition may be triggered by a combination of environmental and genetic factors. External factors that may increase the risk of scalp psoriasis include extremely dry or cold weather, skin trauma, medications, allergic reactions, stress, as well as infections. Certain studies have found that psoriasis would be more prevalent in those with a sedentary lifestyle, inflammatory factors, nutritional deficiencies, and gluten sensitivity. [2]
