Have you noticed the appearance of yellowish or whitish patches on your scalp accompanied by persistent itching? It might be psoriasis.
Scalp psoriasis is a chronic inflammatory skin condition that affects about 2-3% of the global population. While it’s not contagious, in severe cases, it can significantly impact daily life, making it a condition that requires serious attention.
Although it is a well-recognized condition, scalp psoriasis remains poorly understood. There is no definitive cure yet, and its symptoms can sometimes be mistaken for seborrheic dermatitis or simple dandruff. This condition can affect just the scalp or spread to other parts of the body, making a proper diagnosis crucial.
A medical professional or dermatologist can confirm if your symptoms point to scalp psoriasis, eczema, seborrheic dermatitis, or just ordinary dandruff. While the symptoms are often straightforward to identify, determining the exact cause can be more challenging. The good news? Psoriasis does not always lead to hair loss, and there are treatments available to manage and minimize its impact.
Symptoms of Scalp Psoriasis
Scalp psoriasis manifests as patches of red, yellow, or white plaques that produce thick, flaky scales. These scales may shed as whitish-yellow flakes, and if scratched, they can result in pinkish crusts and further irritation. It’s essential not to confuse these plaques with the scales caused by seborrheic dermatitis, which are linked to the Malassezia fungus, or with ordinary dandruff caused by Pityriasis.
Frequent and intense itching is a common symptom. If left unchecked, scratching can worsen the condition, causing the plaques to spread and making treatment more challenging. It’s crucial to resist the urge to scratch, as this aggravates the skin and accelerates cell turnover, worsening the lesions.
The affected areas often feel thick to the touch, with well-defined edges. The plaques are typically found at the hairline, around the ears, and at the nape of the neck, making them easily visible and often uncomfortable.
Causes of Scalp Psoriasis
Similar to other forms of psoriasis, scalp psoriasis results from an abnormally rapid turnover of epidermal cells (keratinocytes). While the exact triggers remain unclear, this condition is recurrent, with unpredictable relapses even after years of remission.
Three primary factors are believed to contribute to the onset of scalp psoriasis: autoimmune response, genetic predisposition, and psychosomatic factors.
Autoimmune response: A misdirected immune response triggers inflammation and rapid skin cell production.
Genetic predisposition: Family history plays a significant role, especially when combined with other health conditions.
Psychosomatic factors: While not necessarily the root cause, stress significantly exacerbates flare-ups.
Additional aggravating factors include certain medications (e.g., beta-blockers), emotional or physical trauma, smoking, and alcohol consumption.
These factors can intensify symptoms and increase the frequency of flare-ups.
How to Treat Scalp Psoriasis
Although there is no permanent cure for scalp psoriasis, early and consistent management can alleviate symptoms and prevent further complications. If you notice initial signs such as small white plaques or yellow crusts, it’s essential to take immediate action.
Topical Treatments
The first step in treatment focuses on soothing the scalp to minimize discomfort and inflammation. Gentle yet effective emollients are key to softening and removing the scales without causing further irritation.
Before shampooing, applying vegetable oils (with or without essential oils) can hydrate the scalp and aid in eliminating flakes. While medicated shampoos, often antifungal, are commonly prescribed, they are usually part of a more comprehensive treatment plan.
At Novesthetica, we recommend a tailored treatment approach that may include anti-inflammatory and purifying lotions to help reduce itching and calm inflamed areas, soothing and antiseptic creams formulated with botanical extracts to heal and restore the skin, and gentle shampoos that cleanse effectively without being too harsh on the sensitive scalp. Look for shampoos free of sulfates and parabens to maintain the scalp’s balance.
For optimal results, we advise massaging the scalp gently while applying these products to stimulate blood circulation and enhance their absorption.
Vitamin D and Sunlight
A deficiency in vitamin D is often linked to psoriasis flare-ups. We recommend consulting a healthcare provider to test for deficiencies and, if necessary, consider supplements. Regular intake of vitamin D (e.g., monthly ampoules) has been shown in studies to reduce the severity of psoriasis symptoms.
While sunlight can positively affect psoriasis on other parts of the body, its impact on scalp psoriasis is limited since hair blocks UV rays.
Managing scalp psoriasis requires a multifaceted approach that addresses the symptoms, minimizes triggers, and provides consistent care. With the right treatments and lifestyle adjustments, it is possible to regain comfort and improve scalp health.
