Scalp psoriasis is more than just a cosmetic nuisance; the persistent itching, flaking, and redness can disrupt sleep, stain collars, and erode confidence. Effective relief requires a targeted formulation, typically built around active ingredients like coal tar or ketoconazole, that works to slow cell turnover and calm inflammation without stripping your hair of its natural moisture.
I’m Mohammad — the founder and writer behind ProteinJug. My deep market research involves analyzing clinical data, comparing active ingredient concentrations, and evaluating real-user feedback across dozens of scalp treatment formulations to identify which shampoos truly deliver on their promises.
This guide breaks down the most effective options available, from gentle daily-use formulas to intensive treatment shampoos. My goal is to help you find the right best psoriasis shampoo for your specific scalp type and severity level.
How To Choose The Best Psoriasis Shampoo
Selecting a psoriasis shampoo requires matching the active ingredient to your symptom severity. Mild flaking may respond to gentle formulas, while persistent plaques often demand a higher concentration of a proven therapeutic agent.
Active Ingredient
Coal tar is the most common OTC treatment for scalp psoriasis. It works by slowing the rapid growth of skin cells, reducing scaling and itching. Ketoconazole is an antifungal that targets the yeast *Malassezia*, which can exacerbate seborrheic dermatitis and some forms of psoriasis. Salicylic acid helps soften and remove scales, making it a useful supplement in a rotation.
Hair Type and Sensitivity
Strong medicated shampoos can be drying, especially to color-treated, chemically processed, or naturally dry hair. Look for formulas that are fragrance-free, dye-free, and PABA-free if you have a sensitive scalp. Pairing a medicated shampoo with a high-quality conditioner is almost always necessary to prevent brittleness and breakage.
Scent and Residue
Coal tar shampoos have a distinct, industrial odor that many users find off-putting, though the scent typically fades after rinsing and conditioning. If scent is a primary concern, ketoconazole-based options or mild-scented tar gels are better choices. Consider how easily the shampoo rinses out to avoid leaving a greasy or sticky residue on the scalp.

In‑Depth Reviews
1. DHS Person & Covey T Gel Shampoo
The DHS T Gel Shampoo delivers a refined coal tar gel formula that produces a deep, rich lather — a significant upgrade from the thinner, runnier consistency of many standard tar shampoos. Users consistently report that this formula clears plaque buildup and calms itching within a few washes, often outperforming the now-discontinued Neutrogena T-Gel. The mildly scented profile is a notable advantage, offering a faint lemon-like note that dissipates quickly after rinsing, making it far more pleasant for regular use than unscented tar options.
Conditioning is still recommended, as the gel can be drying with daily use. Many reviewers found that a little goes a long way, making the 8-ounce bottle last for weeks even with frequent washing. The paraben-free formulation adds appeal for those seeking a cleaner ingredient profile in their medicated hair care.
This shampoo hits the sweet spot between therapeutic power and user experience. It clears scales, reduces itch, and leaves hair feeling clean without the heavy chemical odor that turns many people away from coal tar treatments.
Why it’s great
- Rich, effective lather with refined coal tar
- Mild, pleasant scent that doesn’t linger
- Outperforms many competitor tar shampoos
Good to know
- Can be drying; needs a good conditioner
- May not eliminate flakes entirely for severe cases
2. Nizoral Anti-Dandruff Shampoo (1% Ketoconazole)
Nizoral is the go-to option when fungal overgrowth is a primary driver of your scalp issues. With 1% ketoconazole, it attacks the root cause of dandruff and seborrheic dermatitis by killing the *Malassezia* fungus, which often exacerbates psoriasis symptoms. Users see results quickly — often within 2-3 uses — reporting a dramatic reduction in stubborn flaking and scalp itch. The fresh scent is a welcome departure from the medicinal notes of coal tar shampoos.
The trade-off is significant drying power. Reviewers universally recommend pairing Nizoral with a heavy conditioner to prevent hair from becoming brittle and straw-like. The recommended twice-weekly usage schedule is easy to maintain, and a single bottle can last several months with this cadence. It’s also gentle enough for color-treated and chemically processed hair, which limits damage.
For anyone whose scalp condition seems to have a fungal component — itching that intensifies with sweat or season changes — Nizoral offers a targeted, clinically proven solution that works without the tar smell.
Why it’s great
- Fast-acting antifungal targets root cause
- Pleasant fresh scent
- Safe for color-treated hair
Good to know
- Very drying; requires heavy conditioner
- Less effective for thick plaque psoriasis
3. Person & Covey DHS Tar Shampoo (8 oz)
This DHS Tar Shampoo is the ideal choice for those with sensitive skin who need relief without added irritants. It is completely fragrance-free, dye-free, and PABA-free, stripping away potential allergens that can worsen scalp inflammation. The formula effectively removes built-up residue and scales without stripping natural moisture, making it gentler than many competing tar shampoos on the market.
The lack of fragrance means you get the full industrial cleaning smell of coal tar, which fades after conditioning. Some users find it pricey for an 8-ounce bottle, but the high-quality ingredients and non-irritating formulation justify the cost for those with highly reactive skin. It’s a staple brand that has been family-owned since 1941, indicating a long-standing reputation in dermatological care.
If your scalp is red, angry, and reacts to everything, this is the safest starting point for tar-based therapy. It provides the therapeutic benefits of coal tar without the risk of further sensitization from perfumes or dyes.
Why it’s great
- Fragrance and dye-free for sensitive scalps
- Gentle yet effective at removing scales
- Trusted, long-standing brand in dermatology
Good to know
- Strong tar odor (no scent to mask it)
- Smaller bottle size for the price point
4. DHS Coal Tar Shampoo (8 oz, Pack of 3)
For those who have found their ideal formula and want to stock up without thinking about it, this 3-pack of DHS Coal Tar Shampoo is the most efficient purchase. It offers the same therapeutic, unscented coal tar formula as the single bottle, but at a per-bottle cost that is significantly lower. This version is fragrance-free and dye-free, making it a reliable workhorse for daily maintenance.
Users report it is excellent for preventing flare-ups when used consistently, and many note that it leaves hair feeling clean and soft without the excessive dryness associated with some medicated washes. The unscented nature is a double-edged sword: it is better for sensitive skin, but the pure tar smell is more noticeable in the bottle compared to scented alternatives. The smell does not linger after conditioning.
This pack is the best choice for anyone who uses a psoriasis shampoo daily and wants to secure a multi-month supply. It delivers the same active ingredient performance as premium options at a price that makes consistent treatment affordable.
Why it’s great
- Excellent value per ounce in a multi-pack
- Effective for daily maintenance and prevention
- Fragrance-free and dye-free
Good to know
- No added scent to mask the tar smell
- Large commitment in volume for one formula
5. MG217 Psoriasis Treatment Medicated Ointment
This is not a shampoo, but a 2% coal tar ointment designed for intensive spot treatment. It is invaluable for tackling stubborn psoriasis plaques on the body, or for applying directly to the hairline and other isolated scalp areas between washes. The ointment base is thick and greasy, which helps it stay in place and penetrate stubborn scales, but it is messy and can stain clothing and bedding.
Users advise applying it after showering and covering the area for maximal absorption. The results are fast and dramatic: flaking can cease within hours, raised plaques flatten in 2-3 days, and redness fades. The smell is a major drawback — reviewers compare it to road construction or motor oil — but the therapeutic results are hard to match for localized, resistant patches. The greasy texture makes it unsuitable for full scalp coverage.
For anyone dealing with a few persistent spots that refuse to respond to shampoo alone, this ointment is a powerful adjunct therapy. Consider it the heavy artillery for your psoriasis treatment arsenal.
Why it’s great
- Fast and dramatic relief for localized plaques
- High 2% coal tar concentration
- Moisturizing base helps retain skin moisture
Good to know
- Very thick, greasy, and messy to apply
- Strong, lingering tar smell
- Stains clothing and sheets
