Psoriasis on the Scalp: Symptoms, Causes and Treatment Options

Psoriasis is a common skin problem that typically features scaly, itchy, symmetrical rashes. It often affects the scalp, causing mild flaking like dandruff or thick, raised, inflamed lesions beyond the hairline.

Scalp psoriasis is a chronic autoimmune condition with no cure. Those who are genetically predisposed to psoriasis can get it triggered by some medications, lifestyle habits, injuries, infections, or cold, dry weather. The scalp psoriasis symptoms can be effectively managed with the help of a dermatologist-recommended psoriasis treatment in Bangalore if it's diagnosed early.

If you are looking for relief from your itchy, scaly rashes on the scalp, read on to first understand all about scalp psoriasis- its symptoms, causes, and treatment options. This knowledge is important so that you consult a dermatologist early for confirmation and suitable treatment.

What is Scalp Psoriasis?

Scalp psoriasis is one of the psoriasis forms where the immune system mistakenly attacks healthy skin of the scalp and speeds up the skin cell turnover. As the scalp skin cells multiply rapidly, the cells pile up to cause thick, crusted, inflamed patches with powdery silvery scales and mild-to-extreme itching. These patches are not contagious.  

How Does Scalp Psoriasis Look?

The symptoms of scalp psoriasis can vary from one individual to another and may come and go in flare-ups.

Here are the main signs indicating the need to see a dermatologist:

• Scalp plaques often extend to the forehead, around the ears, and back of the neck

• Temporary hair shedding due to repeated scratching, severe ongoing inflammation of affected areas of the scalp, thick scales removal, and the stress linked to psoriasis flare-ups

• Bleeding or secondary skin infection (in severe cases because of extreme scratching)
• Raised, discolored skin patches with well-defined borders
• Pink or red plaques on lighter skin to purple, violet, or dark brown on darker skin of the scalp
• Thick plaques covered with a powdery or silvery sheen

• Mild to severe, persistent itching
• Soreness or burning sensation.

What Causes Scalp Psoriasis?

There is no definite underlying reason. Dermatologists believe it to be an autoimmune condition with a genetic predisposition. 

However, the psoriasis flare-ups are usually triggered by:

• Scrapes, cuts, sunburns, or use of harsh chemical-based hair products that traumatize the scalp skin
• Certain medications like beta-blockers for hypertension or anti-malarials
• Early identification and avoidance of such triggers can help reduce psoriasis outbreaks
• High emotional or physical stress
• Infections like strep throat
• Excessive smoking
• Alcohol abuse
• Cold, dry weather.

How is Scalp Psoriasis Treated?

The best treatment for psoriasis on the scalp can only be determined by a dermatologist with a thorough evaluation. It will be the one that works best, depending on the extent of scalp psoriasis.

Generally, the recommended treatments for scalp psoriasis are:

• Medicated shampoos with salicylic acid or coal tar
• Topical corticosteroids that help soothe inflammation
• Vitamin D analogs that help slow down the skin cell turnover
• Topical calcineurin inhibitors that help suppress an overactive immune system (considered in selected cases)
• Phototherapy with Narrowband UVB, PUVA, or excimer laser) that help suppress immune system activity, reducing the rate of skin cell growth, and calming inflammation in severe cases of scalp psoriasis
• Oral medications or injectable biologics that help treat autoimmunity in moderate to severe psoriasis.

To ensure effective management of scalp psoriasis symptoms, regular follow-ups with a dermatologist are a must, irrespective of the treatment considered.

When to Consult a Dermatologist?

If you want early, best control of your psoriasis symptoms and prevention of complications, see a dermatologist as soon as possible if you:

• Experience persistent itchy, scaly, thick plaques on scalp
• Don’t get relief from anti-dandruff shampoo
• Suspect psoriasis and want confirmation
• Have bleeding or signs of infection
• Are losing hair.

Conclusion

Scalp psoriasis is a chronic skin condition believed to be caused by an overactive immune system and genetic factors and triggered by some medications, skin injury or infection, bad lifestyle habits, and weather conditions. Its symptoms are manageable if recognized early.
