Tarsum Coal Tar Psoriasis Shampoo & Conditioner 8 oz – Extra Strength 10% LCD, Beta Hydroxyacid Exfoliating Gel

Tarsum Extra Strength Psoriasis Shampoo is an 8 oz coal tar-based shampoo and conditioner designed to exfoliate flaky scalp skin, soothe itching, and help manage symptoms of psoriasis, seborrheic dermatitis, severe dandruff, and eczema.

This concentrated leave-in gel combines a 10% liquor carbonis distillate (coal tar) solution with a beta hydroxyacid formula to loosen and remove excess dead skin, calm visible redness, and help restore moisture balance on the scalp. It is formulated to be applied before showering and left on dry hair for anywhere from five minutes up to one hour depending on the level of action you want. Tarsum’s texture is a gel-like shampoo and conditioner that lathers at rinse and is intended to provide both immediate ease and support for scalp skin over time.

How should I use this shampoo for the best results?

Apply Tarsum to a dry scalp before washing and leave it in place between 5 minutes and 1 hour, then rinse and follow with your regular shower routine. The product is designed as a leave-in treatment that becomes a rinse shampoo/conditioner when you wet and lather it in the shower.

• Apply on dry scalp to targeted plaques or large areas.
• Leave for 5–60 minutes depending on desired intensity.
• Rinse thoroughly and shampoo again if needed for residue.
• Use frequency as tolerated and recommended by your clinician.

What ingredients make this effective for flaky or itchy scalps?

Tarsum combines 10% liquor carbonis distillate (coal tar) with beta hydroxyacid chemistry to address excess scale and promote a clearer scalp surface. Coal tar helps soften and loosen thickened skin while the beta hydroxyacid supports gentle exfoliation to remove dead skin cells.

• 10% LCD (coal tar) for exfoliation and scale-softening action.
• Beta hydroxyacid to help reduce buildup and smooth texture.
• Gel base that seals in moisture while allowing active penetration.
• Formulated as a shampoo + conditioner to clean and condition simultaneously.

Can I use this with colored or chemically treated hair?

Tarsum is formulated as a therapeutic scalp product; users with dyed or chemically treated hair should consider how active ingredients may interact with treatments. Because coal tar and exfoliants can affect hair color or processed hair, test on a small section first or consult a stylist or clinician if you have recently colored, permed, or chemically treated hair.

• Patch-test on an inconspicuous area before full use.
• Avoid overlapping with fresh chemical treatments immediately after application.
• Rinse thoroughly and condition if hair feels dry after use.
• Follow professional advice for combined cosmetic and therapeutic regimens.

How long before I should expect to notice improvement?

Individual responses vary; some users notice reduced flaking and less irritation after a few applications, while structural improvement in scalp skin may take several weeks of consistent use. Because Tarsum is designed to support healing over time, regular, correct application typically delivers the best outcomes.

• Initial relief (less flaking/itch) can appear after a few uses.
• Noticeable changes in plaque and scalp texture often require weeks.
• Consistency—using as directed—supports longer-term management.
• Consult a healthcare professional for persistent or worsening symptoms.

Who is this for: Tarsum Extra Strength Psoriasis Shampoo is intended for adults seeking a targeted, over-the-counter scalp treatment for persistent flaking, plaque, and itching associated with scalp psoriasis, seborrheic dermatitis, severe dandruff, or eczema. It suits people who want a leave-in pre-shower gel that doubles as a cleansing conditioner, those who prefer coal tar–based therapy, and anyone looking for an exfoliating approach to reduce buildup and improve scalp comfort. If you have sensitive skin, are pregnant, nursing, or have concerns about product interactions with other scalp therapies, consult a clinician before use.
