Living with psoriasis on the scalp or body means a constant battle against relentless itching, embarrassing flaking, and the stubborn, red patches that never seem to settle. The wrong soap or shampoo can aggravate the inflammation instantly, turning a simple shower into an irritant. Finding a cleanser for psoriasis means targeting the root cause: managing the build-up, calming the inflammation, and avoiding ingredients that strip the skin’s delicate moisture barrier.

I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent years analyzing dermatological formulations, cross-referencing active ingredient concentrations like coal tar percentages and pine tar purity, and filtering through thousands of consumer trials to identify which cleansers actually deliver relief for psoriasis-prone skin without causing secondary irritation.

This guide breaks down five proven options ranging from classic medicated shampoos to natural tar-based bars, comparing their active ingredients, residual scents, and real-world results so you can finally find a routine that keeps your scalp calm and your skin clear. the best cleanser for psoriasis depends on whether you need heavy-duty flake control, a fragrance-free solution for sensitive skin, or a natural alternative that won’t compromise on effectiveness.

How To Choose The Best Cleanser For Psoriasis

Psoriasis cleansers work by slowing the rapid skin cell turnover that causes plaque build-up, while reducing the inflammation that drives the itch. The active ingredients and the delivery format (shampoo, gel, or bar soap) determine how effective a product will be for your specific scalp or body symptoms. Focus on coal tar percentages, the presence of fragrances or dyes, and whether the formula leaves a residue that continues working after rinsing.

Coal Tar Concentration

The most clinically proven active ingredient for scalp psoriasis is coal tar. Look for products containing between 0.5% and 1% coal tar — this is the therapeutic range shown to slow cell turnover, reduce scaling, and relieve itching. Higher concentrations are not necessarily more effective and often come with a stronger medicinal odor. Some cleansers use refined coal tar gel, which provides a longer-lasting residual effect than standard shampoo formulas, extending the period between flare-ups.

Fragrance and Dye Sensitivity

Psoriasis-affected skin is hypersensitive to chemical irritants. Many premium cleansers are fragrance-free and dye-free, which minimizes the risk of contact dermatitis. Peppermint, lavender, and other essential oils can sting broken skin, so a truly unscented formula is often safer for daily use. However, natural tar-based cleansers (like pine tar) have a distinct earthy smell that some users find therapeutic, but it may be too strong for those with fragrance sensitivity.

Residual Action vs. Rinse-Only

Gel-based coal tar shampoos continue working on the scalp even after rinsing, which means you get prolonged symptom control between washes — ideal for moderate to severe psoriasis. Standard liquid shampoos with the same active ingredient may require more frequent application. If you prefer a bar soap for the body, pine tar offers deep antibacterial cleansing but lacks the sustained residual effect of a gel formulation, so it may need to be used daily for consistent results.

Best Overall

1. DHS Person & Covey Coal Tar Shampoo (Pack of 2)

Fragrance FreeCoal Tar 0.5%

DHS delivers a twin-pack of its refined coal tar shampoo, each 8-ounce bottle formulated with 0.5% coal tar — the exact concentration dermatologists recommend for moderate scalp psoriasis and seborrheic dermatitis. Users consistently report immediate relief from itching and flaking after the first wash, with many noting that a single bottle lasts weeks because a little lather goes a long way. The fragrance-free formula means no essential oil sting on broken skin, a critical advantage for sensitive scalps.

The packaging is deliberately unpretentious — a recyclable, easy-open bottle that prioritizes function over aesthetics — but the results speak louder than design. Multiple verified purchasers describe it as the “best tar shampoo ever used,” citing complete cessation of flare-ups even during seasonal changes that previously triggered outbreaks. The residual odor is described as much less intense than Neutrogena T-Gel, fading entirely after conditioning.

Some users with fragrance sensitivity note that the smell, while mild, is still present enough to require alternating with another shampoo on certain days. The pack-of-2 format is ideal for those who want uninterrupted supply, though the per-bottle price places it at the premium end — but the efficacy justifies the investment for anyone tired of cycling through ineffective anti-dandruff formulas.

Why it’s great

  • Clinically relevant 0.5% coal tar concentration for proven relief
  • Fragrance-free and dye-free formulation minimizes irritation
  • Residual action extends relief between washes

Good to know

  • Fragrance-sensitive users may still detect a mild tar smell
  • Higher price per bottle compared to single-pack alternatives
Rich Lather Choice

2. DHS Person & Covey T Gel Shampoo

Refined Coal Tar GelMildly Scented

DHS T Gel Shampoo uses a refined coal tar gel formula that produces a rich, dense lather — a sensory upgrade over thinner liquid shampoos. The gel base continues to treat the scalp even after rinsing, which means the therapeutic effect extends beyond the shower. Users with seborrheic dermatitis and thick, oily patchy dandruff report that this formula clears build-up more effectively than the now-discontinued Neutrogena T-Gel.

The scent is a notable departure from the raw industrial odor of many coal tar shampoos: reviewers describe a medicated smell with a light lemon undertone that rinses clean without lingering. One long-term user noted that it extends the gap between washes from 2-3 days to 4-5 days for both flaking and greasiness — a meaningful difference for anyone managing scalp psoriasis alongside a busy schedule.

While the 8-ounce bottle is smaller than the budget-friendly 16-ounce options, the concentrated gel formula requires very little product per wash, making it last longer. Some users still report that flakes are not eliminated entirely, suggesting that very severe cases may need a rotation with a stronger coal tar concentration or an additional treatment shampoo for full control.

Why it’s great

  • Refined coal tar gel provides residual therapeutic action
  • Light lemon scent masks the typical tar odor
  • Rich lather means smaller amounts go further

Good to know

  • Severe psoriasis may still require supplementary treatments
  • Smaller bottle size compared to value-pack alternatives
Natural Alternative

3. Grandpa’s Pine Tar Soap (Pack of 2)

Natural Pine TarBar Soap

For those who prefer a natural — and format that works on both scalp and body — Grandpa’s Pine Tar Soap is a standout. Each 4.25-ounce bar delivers deep antibacterial cleansing without the synthetic chemicals found in many liquid shampoos. Pine tar has been used for generations to soothe irritated, dry skin, and the anecdotal evidence here is powerful: multiple reviewers report that it cleared severe scalp sores, scabs, and bleeding after years of failed treatments from dermatologists.

The scent is the defining characteristic: a smoky, earthy aroma reminiscent of a campfire or peated Scotch whisky (Ardbeg 10 is a common comparison). It does not linger on the skin or hair after rinsing — it stays in the bathroom. Users who lather it on their scalp for ten minutes before rinsing see symptom reduction within a few uses. One verified buyer noted that their scalp lesions healed completely in about a week, though symptoms return if they discontinue use.

The bar format is less convenient for those with long hair or for quick showers, and the price per ounce is higher than many liquid shampoos. Some users find the smoky smell too strong, especially if they have sensitivity to natural tar. It is best for those who want a clean, non-toxic option and are willing to adjust their routine to accommodate the bar soap format.

Why it’s great

  • Natural pine tar without synthetic additives
  • Works effectively on scalp and body psoriasis
  • Powerful antibacterial action reduces inflammation and sores

Good to know

  • Strong smoky scent may be off-putting to some users
  • Bar format requires lathering and 10-minute soak for best results
Gentle Daily Option

4. Person & Covey DHS Tar Shampoo

Fragrance FreeUnscented

Person & Covey’s original DHS Tar Shampoo is a fragrance-free, dye-free formulation that prioritizes a gentle experience without compromising on the therapeutic coal tar. At 8 ounces, it is a straightforward entry-level option for those who want to introduce coal tar into their routine without the intense smell or harsh additives. Reviewers highlight that it is notably more gentle on hair than many name-brand competitors, leaving hair soft rather than brittle.

The real-world feedback is impressive: one user reported that it not only cleared scalp psoriasis but also resolved psoriasis on their forearms after applying the lather directly to the skin. Another verified purchaser noted its effectiveness on their Chihuahua’s dandruff — a testament to its gentle but powerful formula. The unscented nature means no essential oil irritation, and the recyclable bottle aligns with eco-conscious values.

While effective, the price per ounce is higher than the 16-ounce Quality Choice alternative, and some users note that the smell, while mild, is still present as an industrial tar scent that fades with conditioner. It is best suited for those with mild to moderate psoriasis who value a gentle, fragrance-free daily shampoo that can also double as a body wash when needed.

Why it’s great

  • Fragrance-free and dye-free for sensitive skin
  • Gentle formula does not strip hair moisture
  • Versatile for both scalp and body psoriasis

Good to know

  • Mild industrial tar smell still detectable before conditioning
  • Smaller 8-ounce bottle may not last as long for daily use

5. Quality Choice T+Plus Coal Tar Gel Shampoo

16 oz BottleGel-Based

The Quality Choice T+Plus delivers the same 0.5% solubilized coal tar concentration as the premium brands but in a 16-ounce bottle that offers exceptional value for those who need a long-lasting supply. The gel-based formula continues working after rinsing, just like the DHS T Gel, ensuring that the therapeutic effect extends throughout the day. Users report that this shampoo cleared severe scalp flakes and itching after failing both Selsun Blue and Head & Shoulders.

The trade-off is the raw, potent smell: the coal tar odor is noticeably stronger than the lightly scented DHS alternatives. Multiple reviews describe it as “terrible” or “strong,” though most agree this is the price of effective treatment. The gel formula also tends to dry out curly or colored hair, so a deep conditioner is recommended after each wash. For straight or oily hair, this is less of an issue.

This is the obvious choice for those on a strict budget who need a bulk supply or for families managing multiple scalp conditions. The larger bottle reduces the frequency of repurchasing, and the gel base means a small amount goes a long way. It is not the most pleasant sensory experience, but for raw effectiveness per dollar, it is hard to beat.

Why it’s great

  • 16-ounce bottle provides exceptional value per ounce
  • Gel-based formula offers residual scalp treatment
  • Highly effective against stubborn dandruff and scaling

Good to know

  • Strong tar smell that lingers more than premium alternatives
  • Can dry out curly or chemically treated hair

FAQ

Can I use a coal tar shampoo every day for scalp psoriasis?
Yes, but many dermatologists recommend starting with daily use for the first two weeks to break the itch-scratch cycle and reduce flaking, then tapering to 2-3 times per week for maintenance. If your scalp becomes dry or irritated, switch to a fragrance-free conditioner or alternate with a gentle non-medicated shampoo on off days.
Does pine tar soap work as well as coal tar shampoo for body psoriasis?
Pine tar soap is an effective natural alternative for body psoriasis, especially for those who react to synthetic coal tar. It provides deep antibacterial cleansing and can calm inflammation, but it lacks the residual effect of coal tar gel. For mild to moderate body plaques, pine tar used daily (with a 5-10 minute lather time) often delivers excellent results. For severe scalp psoriasis, a dedicated coal tar shampoo is generally more reliable.
How do I remove the tar smell from my hair after using a coal tar shampoo?
Rinse thoroughly with lukewarm water, then apply a generous amount of a strongly scented conditioner or apple cider vinegar rinse (1 tablespoon vinegar per cup of water) and leave it in for 2-3 minutes. Many users also find that a leave-in conditioner with citrus or peppermint helps mask the residual scent. The smell typically fades from hair within 30 minutes but may linger in the shower for longer.

Final Thoughts: The Verdict

For most users, the best cleanser for psoriasis winner is the DHS Person & Covey Coal Tar Shampoo (Pack of 2) because it combines the proven 0.5% coal tar concentration with a fragrance-free formula that works reliably for both scalp and body psoriasis without causing irritation. If you want the rich-lather residual gel action with a lighter scent, grab the DHS T Gel Shampoo. And for a natural alternative that doubles as a body bar, nothing beats the Grandpa’s Pine Tar Soap (Pack of 2).
