What Is Coal Tar Shampoo for Scalp Psoriasis?

 

Scalp psoriasis affects a significant number of people in the UK, causing uncomfortable flaking, itching, and redness that can be difficult to manage day to day. Coal tar shampoo for scalp psoriasis has been used medicinally for well over a century, and Psoriderm Scalp Lotion Shampoo 250ml remains one of the most recognised OTC options available. It contains coal tar solution 2.5% as its active ingredient — a concentration that is effective yet gentle enough for regular use at home. If you've been struggling with a persistently flaky or inflamed scalp, this could be a practical first step before seeking further medical advice. You can also explore our wider skin care range for complementary products.

Psoriasis is a chronic inflammatory skin condition. On the scalp, it typically presents as thick, silvery scales overlying red patches of skin. It's not contagious, and it's not caused by poor hygiene — it's an immune-mediated condition that causes skin cells to renew far too quickly. The NHS estimates that around 1.8 million people in the UK live with psoriasis, and scalp involvement is extremely common.

 

How Does Psoriderm Scalp Lotion Shampoo Work?

 

Coal tar works through several mechanisms that together reduce the hallmark symptoms of scalp psoriasis and seborrhoeic dermatitis. Here's what happens when you use it regularly:

  • Slows keratinocyte proliferation: Coal tar inhibits the abnormally rapid division of skin cells (keratinocytes), which is the root cause of the thick scaling seen in psoriasis.
  • Reduces inflammation: It has mild anti-inflammatory properties that help calm the redness and irritation associated with psoriatic plaques.
  • Antifungal and antibacterial activity: Coal tar also has some antifungal properties, which makes it useful in seborrhoeic dermatitis — a condition partly driven by the Malassezia yeast on the scalp.
  • Antipruritic effect: It helps relieve itching, which is often one of the most distressing symptoms for patients.

The 2.5% coal tar solution in Psoriderm is formulated specifically for scalp use, making it easier to apply and rinse than heavier coal tar preparations. It's worth noting that coal tar is a complex mixture of compounds — its exact mechanism isn't fully understood, but its clinical effectiveness in psoriasis is well established.

 

Who Should Use Psoriderm Scalp Lotion Shampoo?

 

Psoriderm Scalp Lotion Shampoo is suitable for adults and adolescents over 12 years of age who are experiencing scalp conditions that respond to coal tar. It's particularly well suited to those who prefer a shampoo-format treatment over heavier gels or ointments. That said, it's always worth speaking to your pharmacist if you're unsure whether it's right for you.

This product may be appropriate if you:

  • Have been diagnosed with scalp psoriasis and are looking for an OTC maintenance treatment
  • Experience persistent dandruff or seborrhoeic dermatitis that hasn't responded to standard anti-dandruff shampoos
  • Want a medicated shampoo that can be used alongside other scalp treatments
  • Are looking for a convenient, rinse-off format rather than a leave-on preparation

Is Psoriderm Scalp Lotion Shampoo Safe to Store and Use Long Term?

 

Psoriderm Scalp Lotion Shampoo should be stored below 25°C, away from direct sunlight, and kept out of the reach of children. Do not use it after the expiry date printed on the packaging. If you notice any change in colour, consistency, or smell, do not use the product and contact your pharmacist. For those managing ongoing scalp conditions, our hair care collection includes a range of products that may complement your scalp care routine.

Long-term use of coal tar shampoo for scalp psoriasis is generally considered safe when used as directed. However, if your symptoms worsen, spread beyond the scalp, or fail to improve after several weeks of consistent use, you should seek advice from your GP or a dermatologist. Coal tar is not recommended for use on broken, infected, or acutely inflamed skin.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Psoriderm Scalp Lotion Shampoo 250ml

 

What Is Psoriderm Scalp Lotion Shampoo and What Is It Used For?

 

Psoriderm Scalp Lotion Shampoo 250ml is a medicated shampoo containing coal tar solution 2.5% as its active ingredient. It is used to treat scalp psoriasis, seborrhoeic dermatitis, and persistent dandruff. Coal tar is a well-established dermatological treatment that has been used for decades to manage chronic inflammatory scalp conditions. The shampoo format makes it straightforward to incorporate into your regular hair-washing routine without the mess associated with heavier coal tar preparations such as gels or pastes.

Scalp psoriasis causes the skin on your scalp to produce new cells far more rapidly than normal, leading to a build-up of thick, scaly patches. Seborrhoeic dermatitis, meanwhile, is linked to an overgrowth of naturally occurring yeast on the skin. Both conditions can cause significant discomfort and self-consciousness. Psoriderm addresses both by targeting the underlying processes driving these symptoms.

 

What Do You Need to Know Before Using Psoriderm Scalp Lotion Shampoo?

 

Before using Psoriderm, read the following carefully. Do not use this product if any of the contraindications below apply to you.

  • Have broken, cracked, or actively infected skin on your scalp
  • Have acutely inflamed or weeping psoriasis
  • Are under 12 years of age (unless directed by a doctor)
  • Are pregnant or breastfeeding — seek medical advice before use

Warnings and precautions:

  • Avoid contact with eyes, mouth, and mucous membranes — rinse thoroughly with water if contact occurs
  • Coal tar can increase photosensitivity — avoid prolonged sun exposure or UV light treatment on treated areas
  • May cause temporary staining of light-coloured or bleached hair
  • Do not use immediately before or after UV phototherapy without medical advice
  • If your condition worsens or does not improve after 4 weeks, consult your GP

Drug interactions:

  • No significant systemic drug interactions are established for topical coal tar at this concentration
  • Avoid concurrent use with other photosensitising agents on the scalp without medical guidance

Serious allergic reactions to coal tar are rare but possible. Seek urgent medical attention if you experience difficulty breathing, swelling of the face or throat, or a widespread skin reaction.

 

How Should You Store Psoriderm Scalp Lotion Shampoo?

Frequently Asked Questions

Where can I buy Psoriderm Scalp Lotion Shampoo online in the UK?

You can buy Psoriderm Scalp Lotion Shampoo 250ml directly from Cured Pharmacy, a GPhC-registered UK online pharmacy. It is available without a prescription as an over-the-counter medicine, so no GP visit is required. Simply add it to your basket and it will be dispatched to your door.

How does Psoriderm Scalp Lotion Shampoo work in the body?

Psoriderm contains coal tar solution 2.5%, which works by slowing the abnormally rapid turnover of skin cells that causes the thick scaling typical of scalp psoriasis. It also has anti-inflammatory and antipruritic properties, helping to reduce redness and relieve itching. Additionally, coal tar has mild antifungal activity, which is beneficial in seborrhoeic dermatitis.

How do I use Psoriderm Scalp Lotion Shampoo step by step?

Wet your hair and scalp thoroughly, then apply a generous amount of Psoriderm directly to the scalp and massage in gently. Leave it on for 3 to 5 minutes before rinsing thoroughly with warm water. Use two to three times per week, or as advised by your pharmacist or GP.

How often should I use Psoriderm Scalp Lotion Shampoo?

The recommended frequency is two to three times per week for scalp psoriasis, seborrhoeic dermatitis, and persistent dandruff. You should not use it more frequently than directed unless advised by a healthcare professional. Consistent, regular use over several weeks is typically needed to see a meaningful improvement.

How long does it take for Psoriderm Scalp Lotion Shampoo to work?

Some patients notice a reduction in itching and flaking within the first two to four weeks of regular use. Full improvement in scaling and redness may take longer — typically four to eight weeks of consistent use. If there is no improvement after four weeks, speak to your GP or pharmacist.

What are the side effects of Psoriderm Scalp Lotion Shampoo?

The most common side effects include mild scalp irritation, a temporary burning or stinging sensation, and possible staining of light-coloured or bleached hair. Less commonly, folliculitis or increased photosensitivity may occur. If you develop a severe allergic reaction — such as widespread rash, swelling, or difficulty breathing — stop use immediately and seek medical attention.

Who should not use Psoriderm Scalp Lotion Shampoo?

Psoriderm should not be used by anyone who is allergic to coal tar or any of its ingredients. It is also not suitable for use on broken, infected, or acutely inflamed skin, and is not recommended for children under 12 without medical supervision. Pregnant or breastfeeding women should seek medical advice before use.

Can I use Psoriderm Scalp Lotion Shampoo if I colour or bleach my hair?

Coal tar can cause temporary staining of light-coloured, bleached, or chemically treated hair, so caution is advised if you colour your hair. It is worth doing a small patch test on a discreet section of hair before full use. If staining is a concern, speak to your pharmacist about alternative scalp treatments.

Can I use Psoriderm Scalp Lotion Shampoo alongside UV phototherapy?

You should not use Psoriderm immediately before or after UV phototherapy without specific medical advice, as coal tar can increase photosensitivity and may affect how your skin responds to UV light. Always inform your dermatologist or treating clinician about all topical products you are using. They will advise on the safest timing and combination.

Is Psoriderm Scalp Lotion Shampoo suitable for children?

Psoriderm is not recommended for children under 12 years of age unless specifically directed by a doctor. For children with scalp psoriasis or seborrhoeic dermatitis, a GP or paediatric dermatologist should be consulted to identify the most appropriate treatment. Always keep the product out of the reach of children.

What are alternatives to Psoriderm Scalp Lotion Shampoo?

Alternatives include other coal tar shampoos such as Polytar, or salicylic acid-based scalp treatments that help lift scaling. For more persistent or severe scalp psoriasis, a GP may prescribe topical corticosteroids or vitamin D analogues. You can also browse our skin care collection for a range of complementary options.

How long can I use Psoriderm Scalp Lotion Shampoo for?

Psoriderm can be used as a long-term maintenance treatment for scalp psoriasis and seborrhoeic dermatitis, provided it continues to be effective and well tolerated. If your symptoms worsen, change in character, or fail to respond after four weeks, consult your GP. Regular review with a healthcare professional is sensible for any chronic scalp condition.

Does Psoriderm Scalp Lotion Shampoo help with hair loss caused by scalp psoriasis?

Scalp psoriasis can sometimes contribute to temporary hair loss due to inflammation and scratching, and treating the underlying condition with Psoriderm may help reduce this. However, Psoriderm is not a hair loss treatment in itself. If you are concerned about hair thinning, our female hair loss collection includes products specifically designed to support hair regrowth.

What happens if I accidentally get Psoriderm Scalp Lotion Shampoo in my eyes?

If Psoriderm comes into contact with your eyes, rinse immediately and thoroughly with clean, lukewarm water for several minutes. If irritation persists or your vision is affected, seek medical attention promptly. Always take care when applying the shampoo near the hairline to minimise the risk of eye contact.

What does the latest research say about coal tar shampoo for scalp psoriasis?

Coal tar remains a recommended treatment option for scalp psoriasis in UK clinical guidelines, including those from the NHS and NICE, due to its established efficacy in reducing scaling, inflammation, and itch. While newer targeted therapies exist for moderate-to-severe psoriasis, coal tar preparations continue to be a practical and cost-effective first-line OTC option for mild-to-moderate scalp involvement. Research continues to support its use as part of a broader scalp psoriasis management strategy.

How Should You Use Psoriderm Scalp Lotion Shampoo?

Using Psoriderm correctly makes a real difference to how well it works. The shampoo format is designed to be easy to apply during your normal hair-washing routine, but a few simple steps will help you get the most from each application. Always read the patient information leaflet supplied with the product before use.

What Is the Correct Dose of Psoriderm Scalp Lotion Shampoo?

There is no fixed measured dose for Psoriderm — you should apply enough to cover the affected areas of the scalp comfortably. The table below summarises the recommended usage by indication and age group. Do not use more frequently than advised, as this will not speed up results and may increase the risk of irritation.

When Is the Best Time to Use Psoriderm Scalp Lotion Shampoo?

There is no single "best" time of day to use Psoriderm — it can be used whenever you would normally wash your hair. However, because coal tar can increase sensitivity to sunlight, many people prefer to use it in the evening to minimise any risk of sun exposure on the scalp shortly after application. If you use it in the morning, try to keep your scalp covered or avoid prolonged sun exposure for a few hours afterwards.

How Long Can You Use Psoriderm Scalp Lotion Shampoo For?

Psoriderm can be used as a long-term maintenance treatment for scalp psoriasis and seborrhoeic dermatitis, as long as it remains effective and well tolerated. Many people use it on an ongoing basis to keep symptoms under control. That said, if you see no improvement after four weeks of regular use, or if your symptoms worsen at any point, you should stop using the product and consult your GP or pharmacist for further assessment.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Psoriderm Scalp Lotion Shampoo?

Most people tolerate Psoriderm Scalp Lotion Shampoo well, but as with any medicated product, some side effects can occur. Common side effects are generally mild and tend to settle with continued use. If they persist or become bothersome, speak to your pharmacist.

  • Mild scalp irritation or redness at the site of application
  • Temporary burning or stinging sensation on the scalp
  • Staining of light-coloured, bleached, or chemically treated hair
  • Unpleasant odour associated with coal tar

What Are the Less Common Side Effects of Psoriderm Scalp Lotion Shampoo?

Less commonly, some people may experience more noticeable reactions. These are not typical but are worth being aware of, particularly if you have sensitive skin or a history of skin reactions to topical products.

  • Folliculitis — inflammation or infection of the hair follicles, presenting as small red bumps or pustules on the scalp
  • Increased photosensitivity — the scalp may become more sensitive to sunlight or UV light after application
  • Dry or flaky scalp that temporarily worsens before improving

What Are the Serious Side Effects of Psoriderm Scalp Lotion Shampoo?

Serious reactions to Psoriderm are rare but can occur. Allergic contact dermatitis — a reaction to coal tar or another ingredient — may present as a spreading rash, intense itching, or blistering beyond the treated area. In very rare cases, a severe allergic reaction (anaphylaxis) may occur, characterised by swelling of the face, lips, or throat, difficulty breathing, or a sudden drop in blood pressure. If you experience any of these symptoms, stop using the product immediately and seek emergency medical attention.

What Should You Do If You Experience Side Effects of Psoriderm Scalp Lotion Shampoo?

For mild side effects such as temporary irritation or stinging, you may simply need to reduce the frequency of use or ensure you are rinsing the product off thoroughly. If irritation is persistent, discontinue use and consult your pharmacist. For any sign of an allergic reaction — including rash, swelling, or breathing difficulties — stop use immediately and seek urgent medical help. You can also report suspected side effects to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Can Psoriderm Scalp Lotion Shampoo Interact With Other Medicines?

No significant systemic drug interactions have been established for topical coal tar at the concentration found in Psoriderm, as absorption through the scalp is minimal. However, you should avoid using Psoriderm at the same time as UV phototherapy without medical advice, as coal tar can increase photosensitivity and may alter your skin's response to UV treatment. Always inform your GP or dermatologist about all topical products you are using, including OTC shampoos and scalp treatments.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
