Tarsum Extra Strength Psoriasis Shampoo 8 oz — Coal Tar 10% LCD Exfoliating Leave-In Gel for Scalp Psoriasis & Severe Dandruff

Tarsum Extra Strength Psoriasis Shampoo is a coal-tar leave-in shampoo and conditioner gel that exfoliates flaky scalp skin, calms irritation, and seals in moisture to support clearer, less flaky scalp over time.

Designed for people managing scalp psoriasis, seborrheic dermatitis, severe dandruff, or eczema, this 8 oz formula combines a coal tar derivative (liquor carbonis distillate at 10% LCD) with a beta hydroxy acid to help break up excess dead skin and promote a healthier scalp surface. Use it as a pre-shower leave-in treatment for targeted action: the longer you leave it on (between 5 minutes and 1 hour), the deeper the exfoliating and softening effect. The gel texture doubles as a gentle conditioning base, helping hair stay manageable while treating the scalp.

How should I use Tarsum to get the best results?

Apply the gel to a dry scalp before showering, massaging it into areas with visible flakes, redness, or tightness. Leave it on for anywhere from five minutes up to one hour depending on sensitivity and desired intensity, then rinse and shampoo as usual to remove residue.

• Apply to dry scalp for targeted delivery before water contact.
• Leave on 5–60 minutes; longer for stronger exfoliation.
• Rinse and follow with your regular cleansing if needed.
• Use regularly as tolerated for continued scalp support.

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

This treatment contains liquor carbonis distillate (coal tar) at 10% LCD alongside a beta hydroxy acid to help loosen and remove excess skin build-up. Coal tar helps slow the formation of plaque and visible scaling, while the beta hydroxy acid aids physical exfoliation to reveal a smoother scalp surface.

• 10% LCD (coal tar derivative) for addressing flaky, scaly patches.
• Beta hydroxy acid to help dissolve connections between dead cells.
• Gel base that conditions hair while treating the scalp.

Will this leave my hair dry or affect color-treated hair?

The gel is formulated to also act as a conditioner, so it helps seal moisture into the scalp rather than stripping hair. However, coal tar products can sometimes affect hair color; if you have color-treated hair, test a small area first or consult your stylist for compatibility with your specific dye.

• Conditioning gel reduces tight, dry scalp sensation.
• Rinse thoroughly to minimize residue that could mattify hair.
• Patch-test color-treated hair before regular use.

Who is this for: Tarsum Extra Strength Psoriasis Shampoo is intended for adults and teens seeking an over-the-counter scalp treatment for persistent flaking, plaque, or itchiness due to psoriasis, seborrheic dermatitis, severe dandruff, or scalp eczema. It’s suited to those who want a leave-in option with stronger active ingredients (10% LCD coal tar and beta hydroxy acid) and who can follow the leave-on timing guidance. If you have questions about using coal tar or a history of sensitivity, consult a healthcare professional before beginning regular use.
