Scalp psoriasis is a type of psoriasis that affects the scalp. Psoriasis of the scalp can also affect the back of the ears, the forehead, and the neck.
Psoriasis of the scalp is a common ailment. Psoriasis affects 2 to 3% of the world’s population, according to experts. It can lead to more severe psoriasis symptoms if left untreated. It also causes long-term inflammation, which has been linked to serious illnesses like:
- insulin resistance
- high cholesterol
- heart disease
The severity and location of scalp psoriasis determine the treatment options. Treatments for psoriasis on the head, neck, and face are generally gentler than treatments for other parts of the body.
Some home treatments may help reduce scalp psoriasis symptoms, according to anecdotal evidence. These are most effective when combined with medical treatments that have been shown to be effective in treating this condition.
Psoriasis comes in a variety of forms, ranging from mild to severe. The most common type of psoriasis is plaque psoriasis, and scalp psoriasis is a type of plaque psoriasis. Plaques are silvery-red, scaly patches that can appear on any part of the body. The most common type of psoriasis that affects the head, face, or neck is plaque psoriasis.
Scalp psoriasis causes and risk factors
Scientists aren’t sure what causes scalp psoriasis or other types of psoriasis. They believe it occurs when a person’s immune system is compromised.
Psoriasis patients may have an increased production of T cells and neutrophils, two types of white blood cells. T cells are responsible for traveling throughout the body and fighting viruses and bacteria.
If a person has an excessive number of T cells, they may mistakenly attack healthy cells, resulting in the production of more skin cells and white blood cells. In the case of scalp psoriasis, these cells appear on the skin and cause inflammation, redness, patches, and flaking.
Psoriasis can be caused by a variety of factors, including lifestyle and genetics. The following factors may raise your chances of developing scalp psoriasis:
Having a parent with scalp psoriasis increases your chances of developing the disease. If both of your parents have the disease, you’re at an even higher risk of developing it.
Psoriasis of the scalp appears to be more common in people who are overweight. Obese people tend to have more skin creases and folds, which can lead to inverse psoriasis rashes.
If you smoke, you’re more likely to develop psoriasis. Smoking exacerbates the severity of psoriasis symptoms in people who already have it.
Because stress has an effect on the immune system, it has been linked to psoriasis.
Viral and bacterial infections
Psoriasis is more common in people who have recurring infections and weakened immune systems, such as young children and people living with HIV.
Those with scalp psoriasis may notice that a variety of factors aggravate or trigger their symptoms. Typical examples include:
- lack of vitamin D
- alcohol addiction
- infections, including strep throat or skin infections
- skin injuries
- some medications, including lithium, beta-blockers, antimalarial drugs, and iodides
Does scalp psoriasis cause hair loss?
Hair loss is a common symptom of psoriasis of the scalp. When scalp psoriasis is treated and cleared up, hair usually grows back.
