Tarsum Extra Strength Psoriasis Shampoo 4 oz — Coal Tar Leave-In, 10% LCD Exfoliant

Tarsum Extra Strength Psoriasis Shampoo is a coal tar–based leave-in shampoo and conditioner formulated to exfoliate flaky scalp skin, soothe itching, and help reduce visible plaque and redness.

This concentrated 4 oz formula combines a 10% LCD (liquor carbonis distillate) coal tar solution with beta hydroxy acid to soften and lift excess dead skin on the scalp while providing a moisturizing gel base that can be left on before showering. Designed as a leave-in product, it can be applied before washing and left on dry from five minutes up to an hour depending on how much exfoliating action you want. The texture and dosage aim to target scalp conditions like psoriasis, seborrheic dermatitis, severe dandruff, and dry, flaky irritation without requiring daily use.

How do I use this before showering for best results?

Apply a thin layer to the dry affected areas of the scalp where flakes or plaque are visible. Leave the product on for a short period to allow the coal tar and beta hydroxy acid to soften dead skin, then proceed to rinse and shampoo as usual.

• Apply to dry scalp 5 minutes to 1 hour before showering.
• Use a fingertip massage to cover plaques and flaky patches evenly.
• Rinse thoroughly and follow with a gentle shampoo or rinse.
• Adjust leave-on time to your skin’s sensitivity and symptom severity.

What active ingredients are in the formula and what do they do?

The formula centers on 10% LCD coal tar mixed with a beta hydroxy acid. Coal tar helps soften and loosen scale and plaque on the scalp; the beta hydroxy acid aids in exfoliating and clearing excess dead skin cells so the scalp can renew more effectively.

• 10% LCD (liquor carbonis distillate) coal tar for softening and reducing scale.
• Beta hydroxy acid to support gentle chemical exfoliation of dead skin.
• Gel base that conditions and helps seal in moisture while treating.
• Leave-in design for controlled exposure and flexible use.

Can I use Tarsum with other scalp products or styling routines?

Tarsum is designed to be integrated into your existing hair care routine, used intermittently as needed rather than daily for many users. Allow the product to be rinsed and follow with your regular shampoo, conditioner, or styling products once the treatment period is complete.

• Use before showering and rinse before shampooing if combining with other cleansers.
• Not necessary to apply daily—tailor frequency to symptom control and sensitivity.
• Avoid simultaneous use with other strong topical medicated preparations unless advised by a clinician.
• Ideal for use on targeted patches rather than entire scalp when sensitivity is a concern.

How long until I notice improvement and how should I store it?

Individual responses vary; some users see reduced flaking and less visible plaque within a few applications, while others need consistent use over weeks to notice clearer skin. Store the product at room temperature away from direct sunlight and keep the cap tightly closed to preserve potency.

• Visible changes may appear after several treatments; consistency helps.
• Storage: cool, dry place away from heat and sunlight.
• Avoid contact with eyes and broken skin; follow label instructions for safe use.
• 4 oz format is concentrated—apply sparingly to affected areas.

Who is this for: Tarsum Extra Strength Psoriasis Shampoo is intended for adults seeking a targeted coal tar leave-in treatment for persistent scalp flaking, plaque, or itching from conditions such as psoriasis, seborrheic dermatitis, severe dandruff, or eczema-prone scalps. It is suited to people who want a concentrated, leave-in gel they can apply before showering to soften and exfoliate stubborn dead skin while also conditioning the scalp. If you have sensitive skin, are using other topical medicines, or have concerns about interactions, consult a healthcare professional before starting a new medicated scalp product.
