How To Get Rid of Psoriasis on Scalp

by Leading Solution June 7, 2024

Are you suffering from those pesky reddish, scaly patches on your scalp that just won't seem to go away? You’re not alone. Psoriasis is a common issue and can be super frustrating. In fact, 45 to 56 per cent of people suffering from Psoriasis develop it on the scalp.

However, the good thing is that scalp psoriasis is treatable, and even home remedies can help reduce the symptoms of this itchy problem. Here, we’ve got some treatments and home remedies to help you get rid of scalp psoriasis. Let’s dive in!

What Is Scalp Psoriasis?

Psoriasis is a chronic autoimmune disease in which skin cells multiply too quickly. In simple terms, any glitches in your immune system cause the cells in your body to multiply at an abnormal pace and make powdery patches of scaly skin. These patches can be slightly bothersome or intensely itchy and uncomfortable, potentially covering the entire scalp or appearing in isolated spots.

Psoriasis can show up anywhere on your body, but it usually affects the elbows, torso, knees, and scalp. When it hits the scalp specifically, it’s called scalp psoriasis.

Scalp psoriasis can range from just a bit of scaling to full-on crusting over your entire scalp. Sometimes, it might even spread to your forehead, around your nose, in your beard area, or behind and inside your ears.

Some scalp psoriasis symptoms include the following:

Red, inflamed skin covered with thick, silvery-white scales.
Dry scalp that may crack and bleed, especially when scales are disturbed.
Itching varies from mild to severe, which can lead to further irritation or infection due to scratching.
Flaking resembles severe dandruff, shedding larger and more noticeable scales.
Burning or soreness in areas where the inflammation is particularly severe.

If your scaling is mild, it might clear up on its own. But if it's more severe, you might need some treatment. It can take a few months or even longer to get it under control. Once you’ve managed it, using special shampoos or moisturisers can help keep flare-ups at bay.

What does Psoriasis on the Scalp Look like?

Well, are you sure you have psoriasis on your scalp? Because some other skin disorders resemble Psoriasis, and you might get it wrong. For instance, seborrheic dermatitis, eczema, and scalp fungal infection may look like Psoriasis.

So, what does psoriasis look like actually? Psoriasis can look different depending on your skin tone. On lighter skin, it might show up as pink or red with silvery-white flakes. On darker skin, it might look violet with a greyish tone, or even dark brown, making it harder to spot.

Psoriasis not just causes itchy scalp but it can also be painful. The patches might crack and bleed, which can be really uncomfortable.

Causes of Scalp Psoriasis

Scalp psoriasis is not merely a surface-level issue - it’s a complex condition influenced by genetic links and environmental triggers. Let's explore these factors in more detail:

Genetic Factors

At its core, scalp psoriasis has a genetic element. It often clusters in families, suggesting a hereditary blueprint. This genetic tendency involves specific genes linked to the immune system, which somehow go awry, leading to the rapid turnover of skin cells seen in psoriasis. Imagine skin cells multiplying so fast that they don't have time to mature, creating those thick, scaly patches on the scalp. If your parents or siblings have psoriasis, the likelihood of you facing this condition increases.

Stress

Perhaps one of the most common triggers, stress can set off or exacerbate psoriasis. The body’s stress response can stir up inflammation, acting as a catalyst for a flare-up. Many people can recall their first psoriasis outbreak during a particularly stressful period, linking emotional turmoil to physical symptoms.

Weather Conditions

The climate plays a crucial role as well. Cold, dry air can sap the moisture from your skin, making it more prone to psoriasis. Conversely, warm, humid air might relieve symptoms, offering a natural form of relief that many seek eagerly.

Infections

The most common type of infection linked to the onset of scalp psoriasis is a streptococcal infection, such as strep throat. When the body responds to this bacterial infection, the immune system becomes activated in a way that can also exacerbates or triggers psoriasis. This immune response leads to increased inflammation, which in turn accelerates the production of skin cells. On the scalp, this results in the thick, scaly patches characteristic of scalp psoriasis.

Medications

Interestingly, some medications can induce psoriasis in predisposed individuals. Drugs like beta-blockers, used for managing blood pressure, or lithium for bipolar disorder, can be potential triggers. This side effect can be particularly disheartening, as it forces patients to balance necessary medical treatments with their psoriasis management.

How Is Scalp Psoriasis Diagnosed?

To manage scalp psoriasis effectively, the first step to take is to diagnose it. A thorough and accurate diagnosis is essential as scalp psoriasis can resemble other skin disorders. The following is how healthcare providers commonly approach the diagnosis of this challenging skin condition.

Physical Examination

A physical examination is usually the first step in the diagnosis of scalp psoriasis. A dermatologist or other healthcare provider will closely examine the scalp, looking for the distinctive signs of psoriasis. These signs include red patches of skin covered with silvery scales, dry scalp, dandruff-like flaking, and changes in the texture and appearance of the scalp. The edges of these patches are typically well-defined.

During the examination, the doctor might also check other parts of the body because psoriasis can affect various areas simultaneously. They will look for similar patches on the elbows, knees, torso, and nails, which are common locations for psoriasis lesions.

Medical History

A thorough medical history further helps in diagnosing scalp psoriasis. The healthcare provider will ask questions about the patient’s health history, any family history of psoriasis, and the presence of any symptoms such as itching, pain, or bleeding. They will inquire about factors that could influence the condition, such as recent stress, medication usage, or exposure to certain environments.

Biopsy

If the diagnosis isn't clear from the visual exam and medical history, the doctor may perform a biopsy. This involves taking a small sample of skin from the affected area, which is then examined under a microscope. This test helps distinguish psoriasis from other similar-looking skin conditions like seborrheic dermatitis, fungal infections, or eczema.

Other Tests

In some cases, additional tests may be required to rule out other conditions. For instance, a fungal culture might be done to exclude fungal infections, which can mimic the appearance of scalp psoriasis.

Topical Treatments for Scalp Psoriasis

When managing scalp psoriasis, topical treatments and products for scalp psoriasis are often the first strategy recommended by healthcare providers. These treatments are applied directly to the scalp and can significantly alleviate symptoms. However, the treatment also depends on the severity of the condition. Let’s explore the most effective medicated shampoos and creams used to combat this condition according to its severity.

Mild Psoriasis

Look for the shampoo containing either salicylic acid, ketoconazole, or Coal Tar as an active ingredient.

Salicylic acid is excellent for reducing scalp build up, but it’s important not to use it too frequently as it can sometimes weaken the hair shafts and lead to breakage.
Coal tar slows the rapid growth of skin cells and reduces inflammation.
Ketoconazole helps reduce the yeast population on the skin, which might contribute to inflammation and symptoms of psoriasis.

These ingredients reduce the plaque build-up and inflammation associated with scalp psoriasis. But remember, don’t just apply them and remove them with a quick wash as you do with normal shampoos. These medicated shampoos need a good amount of time on your scalp to soften the plaque.

Moderate Psoriasis

If your scalp psoriasis is mild to moderate and is not going away with shampoos, your doctor will suggest something to apply directly on your affected area, such as gels, creams, ointments, foams and lotions. These products contain steroids (corticosteroids) of different strengths, with stronger ones typically used for severe cases.

● Corticosteroid Creams

These are the most commonly prescribed medications for scalp psoriasis. They come in various strengths and can significantly reduce inflammation and ease symptoms. However, they should be used sparingly and not for prolonged periods, as they can lead to skin thinning and other side effects.

● Vitamin D Analogues Creams

These creams (such as calcipotriene) help control the overproduction of skin cells. Unlike corticosteroids, they do not cause skin thinning, making them suitable for longer-term use. While vitamin D analogues are typically safe for treating psoriasis, they might not be the best choice for everyone. If you have certain health conditions or are currently on specific medications, these treatments could lead to drug interactions. For that reason, try to check with your doctor to see if vitamin D analogues are a safe option for you. They can guide you through any potential interactions with your existing medications or health issues, ensuring your treatment plan is both effective and safe.

Applying these creams and ointments can be tricky on hairy areas like the scalp. It’s often recommended to part the hair in sections to ensure the medication is applied directly to the skin.

Severe Psoriasis

If your scalp psoriasis is severe and persistent, you might have to turn to other forms of treatment, such as the following:

Light Therapy for Scalp Psoriasis

Light therapy, also known as phototherapy, is a popular method for treating scalp psoriasis. It works by exposing the scalp to ultraviolet (UV) light under medical supervision, effectively slowing the rapid growth of skin cells associated with psoriasis.

There are two primary types of UV light used:

UVB Phototherapy

This is the most common form of light therapy for psoriasis. Narrow-band UVB light directly targets the DNA in skin cells, helping to reduce their growth rate, which diminishes scaling and inflammation. Sessions typically occur two to three times a week, either in a clinic or at home, using a specialised UVB lamp.

PUVA (Psoralen plus UVA)

This approach combines a light-sensitizing medication called psoralen with UVA light exposure. Psoralen can be taken orally or applied directly to the skin, enhancing its sensitivity to UVA light. This method tends to be more potent than UVB therapy but comes with increased risks, such as premature skin ageing and a higher chance of skin cancer.

Systemic Treatments for Scalp Psoriasis

When scalp psoriasis is severe or stubbornly resistant to other treatments, doctors might recommend systemic treatments. These treatments, which include oral medications and injectables, work throughout the entire body and are potent against psoriasis.

Oral Medications

Methotrexate

A well-established treatment, methotrexate helps calm inflammation and dial down the immune response. Although effective, it requires careful monitoring due to potential side effects like liver damage.

Cyclosporine

This medication quickly curbs symptoms by suppressing the immune system. It's effective for rapid relief but is usually reserved for short-term use because of risks like kidney damage and increased blood pressure.

Acitretin

Related to vitamin A, acitretin slows the production of skin cells. It's an option for those who can't use light therapy, but it carries significant risks, including severe birth defects, so precautions are necessary.

Injectables

Biologics

These advanced drugs are made from living cells and target specific parts of the immune system that drive inflammation. Drugs like etanercept, adalimumab, and ustekinumab can greatly reduce psoriasis symptoms, offering some patients clear skin.

IL-17 inhibitors

These are among the latest in biologic treatments, blocking the IL-17 protein involved in inflammation. Drugs like Secukinumab and Ixekizumab have shown promising results in managing psoriasis symptoms effectively.

Due to the powerful nature of these systemic treatments, regular check-ups with your doctor are essential to ensure they're working as intended and to monitor for any side effects.

Home Remedies to Prevent Scalp Psoriasis

Many people with scalp psoriasis look for natural ways to ease their symptoms. Two herbal remedies that are often recommended for their soothing properties are aloe vera and tea tree oil.

Aloe Vera

Aloe vera is well recognised for its soothing, anti-inflammatory effects. This makes it a great choice for easing the irritation and redness that psoriasis dry scalp can cause. You can apply the gel directly from the plant to the scalp - which helps moisturise the skin, reduce flakiness, and encourage healing. For continuous relief, you can use pure aloe vera gel or products with a high concentration of aloe vera multiple times throughout the day.

Tea Tree Oil

Known for its antiseptic and anti-inflammatory qualities, tea tree oil can also be a valuable tool in your scalp psoriasis care routine. It helps lessen the itchiness and scaling often seen with this condition. Since tea tree oil is quite strong, it’s important to dilute it with a carrier oil like coconut or olive oil before applying it to your scalp to prevent irritation. Mixing a few drops into your regular shampoo or with a carrier oil can provide ongoing symptom management.

Baking Soda

Baking soda helps remove dead skin psoriasis plaque and reduce itchiness. You should mix 2 teaspoons of baking soda with a little warm water to make a paste. Afterwards, apply this paste to your plaques and leave it on for up to 10 minutes. Plus , gently rub the affected area to soften the plaque.

Coconut Oil

Coconut oil traps the moisture to reduce the dryness caused by the psoriasis. Plus, it has anti-inflammatory and antibacterial properties. For better results, gently apply a small amount to the psoriasis plaques, just like you would with any moisturiser. You can also use the oil on your scalp to help loosen the psoriasis scales.

Turmeric

Turmeric is popular for its anti-inflammatory and antioxidant benefits. You can either take a daily turmeric supplement or add more turmeric to your meals. You can use around 1.5 to 3 grams of turmeric daily without any side effects.

Olive Oil

Olive oil helps keep your skin moisturised and can reduce irritation and itching. Apply it directly to the scalp on a regular basis to get effective results for scalp psoriasis.

Lifestyle Changes to Prevent Scalp Psoriasis

You know psoriasis is not completely curable. These medicines and home remedies will reduce the symptoms of psoriasis on the scalp. Once you’ve managed to get your scalp psoriasis under control, maintaining that improvement is key. Regular use of a tar-based shampoo can help keep your scalp in good shape. It’s also beneficial to occasionally apply oil or emollient to your scalp to keep it moisturised.

Here are some additional measures to take:

Wash your scalp gently every day with mild clarifying shampoo and lukewarm water.
Add bath oil, oatmeal, or Epsom salts to your bath and soak for at least 15 minutes.
Use oils or thick ointments to keep your scalp from getting dry.
Spend some time in the sun.
Use a soft-bristled brush to avoid irritating your scalp.

How Long Does it Take to Treat Psoriasis?

Normally, it takes almost 8 to 12 weeks to reduce the symptoms of the scalp psoriasis, but it depends on what treatment your doctor would suggest. The National Institute for Health and Care Excellence (NICE) put out guidelines for treating scalp psoriasis. Here's a simple breakdown of what they suggest, based on the best available evidence.

But keep in mind, this treatment might not work for everyone, but it offers a good starting point.

1. Initial Treatment (Weeks 1-4)

Your doctor will likely start you on a potent corticosteroid, which you’ll need to apply once daily. If corticosteroid does not suit you, Vitamin D is a good alternative.

2. Reassessment (Weeks 4-8)

If you don’t see improvement after 4 weeks, your doctor might switch you to a different form of corticosteroid to better suit your needs. Plus, you would need a scalp treatment, and for that emollient or oil is to be used.

3. Secondary Reassessment (Weeks 8-12)

If you’re still not seeing results, your doctor might prescribe a combined treatment that includes both a potent corticosteroid and vitamin D, applied once daily for up to 4 weeks.

4. Final Options (After 12 Weeks)

If combination or Vitamin D treatments are ineffective, your doctor might recommend a very potent corticosteroid, applied up to twice a day for 2 weeks. Or, might be a Coal Tar treatment once or twice daily. If treatments are still not working, your doctor may refer you to a specialist for more advanced options and personalised advice.
