What Is Capasal Therapeutic Shampoo?

 

If you've been struggling with a flaky, scaly, or irritated scalp — or perhaps your baby has developed the tell-tale crusty patches of cradle cap — capasal therapeutic shampoo could be exactly what you need. This medicated shampoo contains three active ingredients that work together to tackle a range of scalp conditions, from dandruff and seborrhoeic dermatitis to scalp psoriasis and cradle cap. It's available over the counter without a prescription, making it a convenient and accessible option for many people across the UK. You can find it alongside other hair care products at Cured Pharmacy for just £8.49.

Scalp conditions are more common than you might think. The NHS recognises seborrhoeic dermatitis as one of the most frequent causes of a flaky scalp in adults, while cradle cap affects a significant proportion of infants in their first year of life. Having a reliable, clinically recognised shampoo to hand can make a real difference to day-to-day comfort and confidence.

 

How Does Capasal Therapeutic Shampoo Work?

 

The effectiveness of this shampoo comes down to its three-ingredient formula, each component playing a distinct role in treating the scalp:

  • Coal tar (1%): Slows down the overproduction of skin cells on the scalp, which is a key driver of conditions like psoriasis and seborrhoeic dermatitis. It also has mild antifungal and anti-inflammatory properties.
  • Salicylic acid (0.5%): A keratolytic agent that softens and helps lift away scales and crusts, making it particularly useful for cradle cap and psoriatic plaques.
  • Coconut oil (1%): Conditions and moisturises the scalp, helping to counteract the dryness that can accompany scaling conditions and making the shampoo gentler on the skin barrier.

Together, these ingredients address both the cause and the symptoms of common scalp conditions — reducing cell turnover, clearing scale, and soothing the skin simultaneously.

 

Who Should Use Capasal Therapeutic Shampoo?

 

This shampoo is suitable for a broad range of people, from adults dealing with chronic scalp conditions to parents managing their infant's cradle cap. That said, it's not appropriate for everyone, so it's worth checking whether it's right for your situation before you start using it.

Capasal Therapeutic Shampoo is generally suitable for:

  • Adults with seborrhoeic dermatitis of the scalp
  • Adults and older children with scalp psoriasis
  • People experiencing persistent dandruff that hasn't responded to standard shampoos
  • Infants with cradle cap (under pharmacist or GP guidance)

It is not recommended for use on acutely inflamed, broken, or infected skin. If you're unsure whether this product is appropriate for your condition, speak to your pharmacist before use. Parents considering using this on a baby should always seek professional advice first — you'll find a range of relevant products in our baby and toddler collection too.

Is Capasal Therapeutic Shampoo Safe to Store at Home?

 

Yes — storage is straightforward. Keep the shampoo below 25°C, away from direct sunlight, and out of reach of children. Do not use after the expiry date printed on the packaging. The 250ml bottle is a practical size for regular use and fits easily in a bathroom cabinet.

It's also worth noting that coal tar products can occasionally cause photosensitivity. After using capasal therapeutic shampoo, try to avoid prolonged exposure to direct sunlight or UV lamps on the treated areas of your scalp. If you have any concerns about using this product alongside other skin treatments, check with your pharmacist — particularly if you're also using topical creams and ointments on your scalp or nearby 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 Capasal Therapeutic Shampoo 250ml

 

What Is Capasal Therapeutic Shampoo and What Is It Used For?

 

Capasal Therapeutic Shampoo is a medicated scalp treatment containing three active ingredients: coal tar 1%, coconut oil 1%, and salicylic acid 0.5%. It is used to treat a range of scalp conditions where scaling, flaking, and irritation are the main symptoms. These include seborrhoeic dermatitis, scalp psoriasis, dandruff, and cradle cap in infants. It works on the scalp surface and does not enter the bloodstream in meaningful amounts when used as directed.

The NHS describes seborrhoeic dermatitis as a common condition causing scaly patches, red skin, and stubborn dandruff, and notes that medicated shampoos containing coal tar or salicylic acid are among the recommended treatment options. Cradle cap — the infant equivalent — is similarly characterised by greasy, yellowish scales on the scalp and is generally harmless but can be distressing for parents.

 

What Do You Need to Know Before Using Capasal Therapeutic Shampoo?

 

Before using this shampoo, check the following contraindications and warnings carefully:

  • Do not use if you are allergic to coal tar, salicylic acid, coconut oil, or any other ingredient in the formulation
  • Do not apply to acutely inflamed, broken, or infected skin
  • Avoid contact with the eyes — if contact occurs, rinse immediately with plenty of water
  • Do not use near open flames or while smoking — coal tar is flammable
  • Avoid prolonged exposure to sunlight or UV lamps on treated areas due to potential photosensitivity
  • Use with caution in infants — always consult a pharmacist or GP before use in babies
  • Not recommended for use on the face

Regarding drug interactions, no significant interactions with other medicines have been established for topically applied coal tar shampoos used as directed. However, if you are using other topical treatments on your scalp — such as corticosteroid lotions — speak to your pharmacist before combining them. You may also find relevant guidance in our skin care section.

  • No clinically significant drug interactions are currently documented for this product when used topically as directed
  • Inform your pharmacist of all other scalp or skin treatments you are using

What Are the Possible Side Effects of Capasal Therapeutic Shampoo?

 

Like all medicines, this shampoo can cause side effects, although not everyone experiences them. Most side effects are mild and localised to the scalp.

Common side effects:

  • Mild scalp irritation or tingling sensation
  • Temporary redness of the scalp
  • Slight staining or discolouration of light-coloured, grey, or chemically treated hair

Less common side effects:

  • Skin sensitisation or allergic contact dermatitis
  • Increased sensitivity of the scalp to sunlight (photosensitivity)
  • Folliculitis (inflammation of hair follicles) — rare

If you notice any signs of a severe allergic reaction — such as swelling of the face, difficulty breathing, or a widespread rash — stop using the product immediately and seek urgent medical attention. For mild irritation that persists, speak to your pharmacist.

 

How Should You Store Capasal Therapeutic Shampoo?

 

Correct storage helps maintain the product's effectiveness and safety. Follow these guidelines:

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and heat sources
  • Keep the bottle tightly closed when not in use
  • Keep out of the reach and sight of children
  • Do not use after the expiry date printed on the bottle or carton
  • Do not store near open flames — coal tar is flammable
  • Do not dispose of via wastewater or household waste — ask your pharmacist how to dispose of medicines you no longer need

If you're stocking up on healthcare essentials, Capasal Therapeutic Shampoo stores well within these conditions and the 250ml bottle provides a generous supply for ongoing use. Browse our full range of baby and toddler products for complementary items if you're treating cradle cap.

Frequently Asked Questions

Where can I buy Capasal Therapeutic Shampoo online in the UK?

You can buy Capasal Therapeutic Shampoo 250ml directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £8.49. No prescription is needed as it is classified as a General Sale Medicine. It's available for convenient home delivery across the UK.

How does Capasal Therapeutic Shampoo work on the scalp?

The shampoo works through three active ingredients working in combination. Coal tar slows down the excessive production of skin cells that causes scaling, salicylic acid softens and lifts away those scales, and coconut oil moisturises and soothes the scalp. This three-pronged approach addresses both the underlying cause and the visible symptoms of scalp conditions.

How do I use Capasal Therapeutic Shampoo step by step?

Wet your hair thoroughly, apply a sufficient amount of shampoo to the scalp, and massage in gently with your fingertips. Leave it on for a few minutes before rinsing thoroughly with warm water — you can repeat the application if needed. Use as often as required or as directed by your pharmacist or GP.

Can I use Capasal Therapeutic Shampoo on my baby's cradle cap?

Capasal Therapeutic Shampoo is indicated for cradle cap in infants, but you should always consult your pharmacist or GP before using any medicated shampoo on a baby. Keep the product well away from your baby's eyes during application and rinse the scalp thoroughly afterwards. You can also browse our baby and toddler range for additional products suitable for young children.

How long does it take for Capasal Therapeutic Shampoo to show results?

Many people notice a reduction in scalp flaking and scaling within a few weeks of regular use, though this varies depending on the severity of the condition. Consistent use as directed is important — don't expect overnight results with any medicated scalp treatment. If there is no improvement after four weeks, speak to your GP or pharmacist.

What are the side effects of Capasal Therapeutic Shampoo?

Side effects are uncommon but can include mild scalp irritation, temporary redness, or slight discolouration of light-coloured or chemically treated hair. Less commonly, some people may experience increased sensitivity to sunlight on the scalp. If you develop signs of an allergic reaction such as swelling or widespread rash, stop use immediately and seek medical advice.

How do I manage side effects of Capasal Therapeutic Shampoo?

For mild irritation, try reducing the frequency of use and ensure you rinse the shampoo off thoroughly after each application. To manage photosensitivity, avoid prolonged sun exposure on your scalp after use and consider wearing a hat outdoors. If side effects persist or worsen, contact your pharmacist or GP for further guidance.

Who is eligible to use Capasal Therapeutic Shampoo?

This shampoo is suitable for adults, older children, and infants with cradle cap (under professional guidance). It is not suitable for people with known allergies to any of its ingredients, or for use on acutely inflamed, broken, or infected skin. Always check with your pharmacist if you are unsure whether it is appropriate for your specific condition.

What happens if I accidentally get Capasal Therapeutic Shampoo in my eyes?

If the shampoo comes into contact with your eyes, rinse immediately and thoroughly with plenty of clean water. Do not rub your eyes, as this can worsen irritation. If discomfort or redness persists after rinsing, seek medical advice promptly.

What are alternatives to Capasal Therapeutic Shampoo for seborrhoeic dermatitis?

Alternatives include ketoconazole shampoos such as Nizoral, which target the Malassezia yeast associated with seborrhoeic dermatitis, or other coal tar shampoos like T/Gel. The right choice depends on your specific condition and skin type — your pharmacist can help you decide. You can also explore our skin care collection for related products.

How long can you use Capasal Therapeutic Shampoo for?

Capasal Therapeutic Shampoo can be used as a long-term maintenance treatment for chronic scalp conditions such as seborrhoeic dermatitis or scalp psoriasis. However, if your symptoms have not improved after four weeks of regular use, you should consult your GP or pharmacist to review your treatment. Long-term use is generally considered safe when used as directed.

Can I use Capasal Therapeutic Shampoo if I colour or chemically treat my hair?

Coal tar can cause temporary discolouration of light-coloured, grey, or bleached hair, so you should be aware of this risk if your hair is chemically treated. It's advisable to do a small test application first and speak to your hairdresser or pharmacist if you have concerns. The discolouration is generally temporary and cosmetic rather than harmful.

Is Capasal Therapeutic Shampoo safe to use during pregnancy?

There is limited specific safety data on the use of coal tar shampoos during pregnancy, so you should consult your GP or midwife before using Capasal Therapeutic Shampoo if you are pregnant or breastfeeding. Your healthcare professional can weigh up the potential benefits against any theoretical risks and advise accordingly. Do not self-treat without seeking advice first.

What is the latest research on coal tar shampoos for scalp psoriasis?

Coal tar has been used as a treatment for psoriasis for over a century and remains a recognised option in current NHS and NICE guidance for scalp psoriasis management. Research continues to support its efficacy in reducing scaling and cell turnover, particularly in mild to moderate cases. It is often recommended as a first-line or adjunct treatment alongside other topical therapies.

Can Capasal Therapeutic Shampoo be used alongside other scalp treatments?

It can sometimes be used alongside other scalp treatments, but you should always check with your pharmacist before combining products. Using multiple active treatments simultaneously can increase the risk of irritation or unexpected interactions. Your pharmacist can advise on the safest and most effective combination for your individual needs.

How Should You Use Capasal Therapeutic Shampoo?

Using Capasal Therapeutic Shampoo correctly gives the active ingredients the best chance to work on your scalp. Always follow the steps below unless your pharmacist or GP has given you different instructions.

What Is the Correct Dose of Capasal Therapeutic Shampoo?

There is no fixed measured dose for this shampoo — you apply enough to cover the affected area of the scalp. The table below summarises guidance for different indications and age groups to help you use the product appropriately.

When Is the Best Time to Use Capasal Therapeutic Shampoo?

There is no specific time of day that is clinically required for using this shampoo — use it whenever it fits into your routine. However, because coal tar can increase sensitivity to sunlight, many people prefer to use it in the evening or at times when they will not be spending extended periods outdoors immediately afterwards. This is particularly relevant during summer months or if you spend a lot of time in direct sunlight.

How Long Can You Use Capasal Therapeutic Shampoo For?

Capasal Therapeutic Shampoo can be used on an ongoing basis as a maintenance treatment for chronic scalp conditions such as seborrhoeic dermatitis or scalp psoriasis. Many people use it regularly over months or years without significant problems. That said, if you have been using it consistently for four weeks and your symptoms have not improved — or if they worsen at any point — you should stop use and consult your GP or pharmacist for a review of your treatment plan.

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

What Are the Most Common Side Effects of Capasal Therapeutic Shampoo?

Most people use Capasal Therapeutic Shampoo without experiencing any significant side effects. When reactions do occur, they are usually mild and localised to the scalp. Common side effects include:

  • Mild scalp irritation or a tingling sensation during or after use
  • Temporary redness of the scalp
  • Slight staining or discolouration of light-coloured, grey, or chemically treated hair — this is a cosmetic effect of the coal tar and is generally temporary

These effects are usually short-lived and tend to settle with continued use. If irritation is bothersome, try reducing the frequency of application and ensure you rinse the shampoo off thoroughly each time.

What Are the Less Common Side Effects of Capasal Therapeutic Shampoo?

Less commonly, some people may experience more notable reactions. These are not typical but are worth being aware of before you start using the product. Less common side effects include:

  • Allergic contact dermatitis — a skin sensitisation reaction causing redness, itching, or a rash on the scalp
  • Photosensitivity — increased sensitivity of the scalp to sunlight or UV light following use
  • Folliculitis — inflammation of the hair follicles, which is rare but has been reported with coal tar products

If you notice any of these less common effects, reduce the frequency of use and speak to your pharmacist. Avoiding prolonged sun exposure on the scalp after application can help manage photosensitivity.

What Are the Serious Side Effects of Capasal Therapeutic Shampoo?

Serious side effects are rare with topically applied coal tar shampoos used as directed. However, you should be alert to signs of a severe allergic reaction (anaphylaxis), which — though very uncommon — can occur with any medicine. Seek emergency medical attention immediately if you experience:

  • Swelling of the face, lips, tongue, or throat
  • Difficulty breathing or swallowing
  • A sudden widespread rash or hives across the body
  • Dizziness or collapse

What Should You Do If You Experience Side Effects?

For mild side effects such as scalp irritation or redness, try reducing how often you use the shampoo and make sure you rinse it off completely. If the irritation persists beyond a few days or worsens, stop using the product and speak to your pharmacist or GP. You should also report any suspected side effects to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Can Capasal Therapeutic Shampoo Interact With Other Medicines?

No clinically significant drug interactions have been documented for Capasal Therapeutic Shampoo when used topically as directed. However, if you are using other topical treatments on your scalp — such as corticosteroid scalp applications or antifungal lotions — it is sensible to inform your pharmacist before combining them. Using multiple active scalp treatments simultaneously may increase the risk of irritation or reduce the effectiveness of individual products.

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