Ducray Kertyol P.S.O. Shampoo for Psoriasis Scalp, 6.7 oz — Micronized Sulfur & Salicylic Acid, Coal-Tar-Free Soothing Formula

Ducray Kertyol P.S.O. Shampoo is a calming, coal-tar-free cleansing formula that helps loosen and rinse away scales while soothing red, itchy, and irritated scalps prone to psoriasis.

This shampoo combines micronized sulfur and salicylic acid in a gentle base designed for sensitive scalps, offering targeted scalp care without the strong odor or harshness of many medicated preparations. The formulation is intended to be well tolerated and can be used alongside many dermatological treatments. Regular use helps remove visible scaling and reduces the sensations of tightness and discomfort that often accompany scaly scalp conditions.

How does this shampoo reduce visible scales and flaking?

The formula uses salicylic acid as a keratolytic agent to help break down the bonds between dead skin cells, while micronized sulfur supports skin cell turnover. Together they loosen plaques and allow them to be rinsed away during washing, improving scalp texture without excessive scrubbing.

• Salicylic acid gently exfoliates and clears scale buildup.
• Micronized sulfur complements exfoliation and helps rebalance the scalp surface.
• Rinse-off action removes loosened plaques for a smoother scalp finish.

Is it gentle enough for sensitive or irritated scalps?

Yes — Ducray Kertyol P.S.O. Shampoo is formulated to be milder than many traditional medicated shampoos and does not contain coal tar. The cleansing base is designed to minimize sting or excessive drying while delivering active ingredients to the scalp.

• Coal-tar-free formula for a more tolerable user experience.
• Suitable for use on sensitive skin when used as directed.
• Can be incorporated into care routines alongside many prescribed treatments.

How should I use the shampoo for best results?

Apply to wet hair and gently massage the scalp to create a lather, concentrating on areas with visible scales. Leave the foam on the scalp briefly to let active ingredients work, then rinse thoroughly; repeat if needed. Frequency can vary based on scalp condition and clinician guidance.

• Best applied to wet hair, massaged into the scalp for even coverage.
• Allow a short dwell time before rinsing to enhance effectiveness.
• Follow instructions from your dermatologist for frequency and complementary treatments.

Will this affect hair texture or color-treated hair?

The shampoo is designed as a therapeutic scalp treatment rather than a cosmetic styling product, so temporary changes in hair feel may occur as scales are removed. It is generally compatible with routine hair care, but if you have color-treated or chemically processed hair, consider following with a conditioner or asking your stylist for product compatibility advice.

• Primarily targets the scalp; follow with conditioner if hair feels dry.
• Compatible with many hair care regimens, though individualized results may vary.
• Consult a stylist or dermatologist for use with color-treated hair.

Who is this for: Ducray Kertyol P.S.O. Shampoo is intended for people who experience scaly, red, itchy, or irritated scalp conditions and are looking for a tolerable, rinse-off scalp treatment that helps remove plaques. It is appropriate for those who want a coal-tar-free alternative to harsher medicated shampoos and for individuals using other dermatological therapies who need a complementary cleansing product. If you have severe or rapidly worsening symptoms, consult your healthcare provider before starting any new scalp treatment.
