Overview

Scalp psoriasis is a chronic skin condition characterised by the rapid buildup and overproduction of skin cells on the scalp, leading to the formation of well-defined, red, and inflamed areas covered with silvery-white scales or plaques. These scaly patches can cause itching, pain, stinging, and burning sensations. While scalp psoriasis can occur independently, it often accompanies psoriatic plaques on other body areas. The exact cause of scalp psoriasis is not fully understood. Still, research suggests that a combination of genetic predisposition and environmental triggers, such as infections, skin injuries, certain medications, or stress, can lead to a dysfunctional immune system. This dysfunction causes the immune system to mistake healthy skin cells as foreign threats, leading to an inflammatory response and the rapid proliferation of skin cells on the skin surface.¹

Triggers and exacerbating factors

While the underlying cause of scalp psoriasis remains elusive, several factors can act as triggers, exacerbating symptoms or even initiating the condition.

• Stress, a potent modulator of the immune system, is a well-known trigger, with emotional turmoil and chronic anxiety fueling the inflammatory response
• Skin injuries such as sunburn or cuts, can also trigger localised psoriatic flares
• Certain medications, including lithium and beta-blockers, have been linked to psoriasis development or worsening²
• Seasonal changes, with colder, drier climates often worsening symptoms, can pose additional challenges³

Treatment strategies for scalp psoriasis

Fortunately, there are various treatment options available to help individuals manage scalp psoriasis and regain control over their condition. Topical medications applied directly to the scalp, are typically the first line of defence. While corticosteroids can effectively reduce inflammation and itching, their use requires caution due to potential side effects. Vitamin D analogues and calcipotriol preparations slow skin cell growth and promote normalisation, offering long-term benefits. Coal tar, a tried-and-true remedy, can help reduce itching and scaling, although its distinct odour may be a deterrent.³

For more severe cases, phototherapy, which utilises ultraviolet light to reduce inflammation, may be employed. In cases of widespread or severe psoriasis, systemic medications, such as methotrexate and cyclosporine, may be prescribed to suppress the overactive immune system. While each treatment approach has its unique advantages and disadvantages, collaborating with a dermatologist to develop a personalised treatment plan is crucial for optimal outcomes.⁴

Complementary self-care and support measures

In concert with medical therapy, individuals can gain better control over scalp psoriasis through certain complementary measures:

• Use gentle hair care products like fragrance-free shampoos and conditioners formulated for sensitive skin; avoiding chemicals and hair dyes
• Soft brushing techniques when combing hair; silk pillowcases to minimise friction 
• Practising stress-reducing activities like meditation or yoga
• Avoiding known triggers that can exacerbate scalp psoriasis 

Seeking community through patient advocacy organisations and psoriasis support groups can also furnish emotional support and practical self-care suggestions. Psychological counselling may help develop constructive coping mechanisms and self-compassion.^4,6 

Beyond treatment: living comfortably with scalp psoriasis

Managing scalp psoriasis extends beyond medication. Gentle hair care practices, using mild shampoos and avoiding harsh chemicals, are essential. Scalp massages can improve circulation and reduce itching. Stress management techniques such as yoga or meditation, can help mitigate flares. Joining support groups or online communities can provide invaluable peer support and guidance. Remember, scalp psoriasis is a chronic condition, and consistent management, not a cure, is the key to living comfortably.5,6

FAQ’s

My scalp psoriasis seems to be getting worse lately. What could be causing this?

Several factors can trigger or worsen scalp psoriasis flares, including:

• Stress: Emotional turmoil and chronic anxiety can fuel the inflammatory response. Consider stress management techniques like yoga or meditation
• Skin injuries: Sunburn, cuts, or even tight hats can trigger localised flares. Be gentle with your scalp and protect it from the sun
• Medications: Certain medications, like lithium and beta-blockers, can worsen psoriasis. Talk to your doctor about potential interactions
• Seasonal changes: Cold, dry climates often exacerbate symptoms. Consider using a humidifier indoors and protect your scalp from harsh weather
• Diet: While no specific "psoriasis diet" exists, maintaining a healthy, balanced diet can support overall health and potentially reduce inflammation

I'm worried about using topical medications on my scalp. Are there any natural remedies I can try?

Some natural remedies may offer mild relief from itching and scaling, although scientific evidence is limited. Always consult with your dermatologist before trying any new remedies. Potential options include:

• Aloe vera gel: Its cooling and anti-inflammatory properties can soothe itching and irritation⁷
• Apple cider vinegar: Diluted apple cider vinegar may help control the overproduction of skin cells, but be cautious as it can sting
• Tea tree oil: Possessing antiseptic properties, tea tree oil can help reduce inflammation and itching. However, it's potent and must be diluted with a carrier oil (e.g., jojoba oil or coconut oil) before applying it to the scalp. Test a small amount on your arm first to check for sensitivities⁸
• Dead Sea salts: Soaking in baths with Dead Sea salts may help reduce inflammation and soften scales

Is scalp psoriasis contagious?

No, scalp psoriasis is not contagious and cannot be spread through contact. It is an autoimmune condition affecting your own immune system's response to your skin cells.

Can I use regular hair products with scalp psoriasis?

Harsh chemicals and fragrances in some hair products can irritate your scalp and worsen psoriasis symptoms. Look for gentle, fragrance-free shampoos and conditioners formulated for sensitive skin. Avoid harsh styling products and excessive heat when drying your hair.

I'm self-conscious about my scalp psoriasis. How can I manage the emotional impact?

Scalp psoriasis can significantly impact self-esteem and mental well-being. Joining support groups or online communities can provide valuable peer support and understanding. Consider seeking professional counselling if you're struggling with anxiety or depression related to your condition.

Is there any hope for a cure for scalp psoriasis?

While there is currently no cure for scalp psoriasis, ongoing research shows promise in developing new treatments that target the underlying immune mechanisms. Additionally, effective management strategies can significantly improve quality of life and control symptoms. Remember, consistent management, not a cure, is the key to living comfortably with scalp psoriasis.

Summary

Scalp psoriasis, while a chronic and inflammatory skin condition, can be effectively managed through a combination of medical and lifestyle interventions. Understanding the triggers and treatment options empowers individuals to take control and live comfortably. Remember, support and self-compassion are key allies on this journey. Embrace the ongoing learning process, and let's work together to unveil the hope that lies beyond the itch and the scales.
