Selsun Blue Medicated Antidandruff Shampoo — Maximum Strength 1% Selenium Sulfide, 11 fl oz, Cooling Menthol Relief

Selsun Blue Medicated Antidandruff Shampoo is a maximum-strength, 1% selenium sulfide scalp treatment that targets dandruff symptoms—itching, flaking, redness and scaling—while leaving hair soft and refreshed.

If you struggle with persistent dandruff, this 11 fl. oz. bottle delivers an over-the-counter medicated option formulated to control and reduce visible flakes and scalp irritation. The formula pairs the active ingredient selenium sulfide with cooling menthol and a quick-lathering base to cleanse, soothe, and moisturize without SLS, parabens, phosphates, phthalates or silicones. It's packaged for routine use and intended to work as part of a regular hair-care regimen.

How does this shampoo address stubborn dandruff and flaking?

Selenium sulfide is the clinically recognized active that helps reduce flake formation and soothes inflammation linked to dandruff. The product is designed for targeted scalp application to break down the cycle of irritation and visible scaling.

• Contains 1% selenium sulfide, an antifungal agent that helps control flake-associated fungi
• Targets both visible flakes and the itch/redness that accompany dandruff
• Applied to the scalp and lathered for maximum contact with affected areas

Will it dry out my hair or leave it feeling heavy?

This version uses a cleaner base intended to leave hair feeling soft and manageable rather than stripped or weighed down. Cooling menthol is included to add a soothing sensation while the quick-lather system rinses cleanly.

• Cleaner formula formulated without silicones and common harsh additives
• Quick-lathering texture for efficient cleansing and easier rinsing
• Menthol provides a cooling effect while helping hair remain soft after use

How should I use it for best results and how often?

For most users, apply the medicated shampoo directly to the scalp, work into a lather, leave on briefly to allow the active to work, then rinse thoroughly. Frequency can vary depending on symptom severity—follow package directions and consult a healthcare professional for persistent issues.

• Apply to wet hair and massage into the scalp until lather forms
• Let sit for the recommended time per label before rinsing thoroughly
• Use as directed; many people alternate with regular shampoo after symptoms improve

Is this safe to use with color-treated hair or other styling products?

The formula avoids parabens, phthalates and silicones, which can lessen buildup, but medicated shampoos may interact differently with color treatments. If you have chemically treated hair, patch-test or check with your colorist to confirm compatibility and timing around salon services.

• Formulated without SLS and silicones to minimize harsh buildup
• May be used before or after styling products once rinsed completely
• If concerned about hair color fade, consult your stylist before regular use

Who is this for: Selsun Blue Medicated Antidandruff Shampoo is intended for people experiencing dandruff-related flaking, itching, redness or scaling who want a strong, non-prescription scalp treatment.
