Dermaharmony 2% Pyrithione Zinc Shampoo Bar is a fragrance-free, soap-free solid shampoo formulated to help control dandruff and symptoms of seborrheic dermatitis while minimizing plastic waste.

This 4 oz solid shampoo bar combines 2% zinc pyrithione with plant-derived surfactants, argan oil and oat flour to gently cleanse and soothe the scalp without sulfates, parabens or synthetic fragrances. Designed for daily use, the bar produces a rich lather in hard or soft water, rinses clean, and lasts for months when stored to dry between washes. It’s made in the USA using largely plant-based ingredients and avoids animal-derived components.

How does this bar address dandruff and seborrheic dermatitis?

The active ingredient, zinc pyrithione at 2%, helps reduce the flaking and visible signs associated with dandruff and seborrheic dermatitis. The formulation is soap-free and non-drying, so it cleanses without stripping natural oils that help protect the scalp barrier.

• Contains 2% zinc pyrithione to target scalp flaking and irritation.
• Soap-free, pH ~6 to support scalp comfort and moisture balance.
• Argan oil and oat flour added to condition and calm the scalp.
• Use regularly to manage recurrence of symptoms.

What does fragrance-free and soap-free really mean for daily use?

Fragrance-free means no added perfumes or dyes; the bar has a mild, natural detergent-like scent from its surfactant base that does not linger after rinsing. Being soap-free indicates the formula avoids traditional soap chemistry and is built on milder surfactants to limit dryness and irritation.

• No added perfumes or colorants—suitable for fragrance-sensitive users.
• Derived from plant-based surfactants like coco glucoside and SCI for gentler cleansing.
• Leaves minimal residue and rinses clean in hard or soft water.
• Recommended to leave on the scalp for at least 30 seconds for efficacy.

How should I use and store the shampoo bar for best results?

Wet hair and rub the bar directly onto the scalp and hair to generate a lather, or lather in hands first. Massage into the scalp, keep contact for at least 30 seconds, then rinse thoroughly. Proper storage extends the bar’s life.

• Rub on wet hair or in hands, massage scalp, leave 30+ seconds, rinse well.
• Store on a draining soap dish or rack so it dries between uses.
• A single 4 oz bar typically lasts months with daily use.
• Avoid eye contact; rinse immediately if eyes are exposed.
