Coal tar shampoo has been a trusted treatment for stubborn scalp conditions for decades. In Australia, it’s commonly recommended for dandruff, scalp psoriasis, and seborrhoeic dermatitis. While effective for many, it’s not without risks — and knowing how to use it safely is key.
This article covers what coal tar shampoo is, how it works, its benefits and side effects, and the best options available in Australia.
What is Coal Tar Shampoo?
Coal tar shampoo is a medicated shampoo containing coal tar, a by-product of coal processing. It’s used to relieve itching, scaling, and flaking caused by certain skin conditions.
In Australia, coal tar shampoos are widely available over the counter at pharmacies and supermarkets. Popular brands include:
- Neutrogena T/Gel® Therapeutic Shampoo
- Ego Sebitar® Scalp Cleansing Treatment
- Polytar® Scalp Solution
Prescription-strength formulations may be recommended for severe or persistent cases.
How Coal Tar Shampoo Works
Coal tar works by slowing down the overproduction of skin cells on the scalp. In conditions like dandruff and psoriasis, skin cells are replaced too quickly, leading to visible scaling and irritation. Coal tar reduces this rapid cell turnover, helping to:
- Soften and lift scales
- Reduce redness and itching
- Restore a healthier scalp environment
It also has mild antiseptic properties, which can help manage symptoms linked to scalp inflammation.
Benefits of Coal Tar Shampoo
1. Coal Tar Shampoo for Dandruff
Dandruff, often caused by an overgrowth of Malassezia yeast, can lead to flaking and scalp itch. Coal tar shampoo helps reduce scaling and irritation, especially for people with chronic or stubborn dandruff.
2. Coal Tar Shampoo for Psoriasis
Scalp psoriasis can cause thick, silvery scales and redness. Coal tar helps to reduce scaling and inflammation, making it easier to manage symptoms and improve scalp comfort.
3. For Seborrhoeic Dermatitis
This condition causes greasy scales and redness, often around the scalp, eyebrows, and sides of the nose. Coal tar can help slow skin cell turnover and improve symptoms.
4. Long-Lasting Symptom Relief
Some users find these shampoos provide relief that lasts longer between washes compared to other treatments.
How to Use Coal Tar Shampoo Effectively
For best results:
- Read the label carefully – Follow the manufacturer’s instructions exactly.
- Wet your hair thoroughly – This ensures even distribution.
- Massage into the scalp – Focus on affected areas, avoiding contact with eyes.
- Leave on for 3–5 minutes – This allows the active ingredients to work.
- Rinse thoroughly – Residue can cause irritation.
- Frequency – Typically 1–3 times per week, as directed by your healthcare provider.
Tip: Avoid using on broken or infected skin unless directed by a doctor.
Possible Side Effects and Safety Precautions
While coal tar shampoo is generally safe for most adults, it can cause side effects:
- Skin irritation or redness
- Dryness or temporary hair discolouration (especially in light-coloured hair)
- Increased sun sensitivity – Coal tar can make your scalp more prone to sunburn. Wear a hat outdoors after use.
Important safety notes for Australia:
- Avoid prolonged use without medical guidance, particularly for children.
- Not recommended during pregnancy unless advised by a doctor.
- Do not use in conjunction with UV light therapy unless instructed, as coal tar may increase skin sensitivity to light.
Coal Tar Shampoo vs Other Treatments
Other medicated shampoos in Australia may contain:
- Ketoconazole – Antifungal, useful for yeast-related dandruff.
- Zinc pyrithione – Reduces fungal growth and irritation.
- Salicylic acid – Helps remove scales.
Coal tar is often chosen when these treatments don’t fully control symptoms, or when a broader anti-scaling effect is needed.
Best Shampoos Available in Australia
Some of the most trusted options include:
- Neutrogena T/Gel® Original Formula – Widely available, mild scent, suitable for regular use.
- Ego Sebitar® – Combines coal tar with salicylic acid for extra scale removal.
- Polytar® Scalp Solution – Higher coal tar concentration, often recommended for more persistent symptoms.
Always check the concentration of coal tar and other active ingredients, and speak with your pharmacist or doctor before trying a new brand.
When to See a Doctor
Seek medical advice if:
- Symptoms persist after 4–6 weeks of regular use
- You develop significant irritation, rash, or swelling
- You have scalp sores or signs of infection
- Your condition worsens despite treatment
Your GP or dermatologist can assess whether you need a different treatment or a prescription-strength formula.
