Dermaharmony Sulfur & Salicylic Acid Shampoo Bar — 5% Sulfur, 2% Salicylic Peppermint 4 oz, Syndet & Sulfate-Free

Dermaharmony's 5% sulfur and 2% salicylic acid peppermint shampoo bar is a plant-based, non-soap cleansing bar designed to help control flaking and scalp buildup associated with dandruff, seborrheic dermatitis, and psoriasis.

This compact 4 oz bar combines two clinically familiar actives—sulfur to address microbial and surface concerns and salicylic acid to help loosen scale—with a peppermint-scented, syndet (non-soap) base. The formulation uses gentle coconut-derived cleansers, humectant oils and botanical extracts to deliver effective cleansing without harsh sulfates, artificial dyes, or animal testing. Its low pH and foam-boosting ingredients mean it rinses well in both hard and soft water and can last far longer than many liquid shampoos.

How should I use this shampoo bar for best results?

Swap the bar in for your regular shampoo on affected days and lather directly on the scalp or between the palms first. Massage thoroughly for about 60–90 seconds to let the salicylic acid and sulfur contact the flaky or scaly areas before rinsing completely.

• Use at least twice weekly or as directed by your healthcare provider.
• Rub between hands to work up foam or glide the bar across wet hair and scalp.
• Avoid eye contact; rinse immediately if product enters eyes.

What are the active ingredients and what do they do?

The bar contains 5% sulfur and 2% salicylic acid as its active components. Sulfur has a long history in topical scalp care, while salicylic acid is a keratolytic that helps break down and remove scale, letting the cleansing base more effectively lift residue and flakes.

• 5% Sulfur: supports reduction of surface buildup.
• 2% Salicylic Acid: helps soften and remove scaly patches.
• Peppermint oil: provides a fresh scent that helps mask sulfur aroma.

Is this shampoo bar gentle enough for regular use and different water types?

Yes—the bar is a syndet (non-soap) formula with a measured pH around 3.8, designed to be non-drying while still producing a generous lather. It contains mild coconut-based surfactants and moisturizing agents like argan oil and oat flower extract to help maintain scalp comfort during routine use.

• Works in soft and hard water without excess residue.
• Sulfate-free, paraben-free, no artificial colors or fragrances.
• Formulated to outlast multiple bottles of liquid shampoo.

Are there precautions or situations to avoid?

Because this product contains active ingredients that affect skin turnover, avoid using it on large open wounds or extensively irritated skin without professional advice. Discontinue if irritation worsens or fails to improve and consult a doctor if you have concerns or underlying conditions.

• Ask a doctor before using on large body areas or severe conditions.
• Keep away from children; seek medical help if swallowed.
• Stop use and consult a healthcare professional if no improvement occurs.

Who is this for: This bar suits adults seeking a concentrated, travel-friendly alternative to conventional dandruff treatments—especially those who prefer plant-derived cleansing systems without sulfates or artificial additives. It's appropriate for people managing dandruff, seborrheic dermatitis, or psoriasis-related scalp flaking who want a longer-lasting, lower-waste option that balances targeted actives with gentle, botanical support.
