Dermaharmony Zinc Pyrithione Shampoo Bar — 2% Pyrithione Zinc Tea Tree, 4 oz, sulfate-free dandruff control

Dermaharmony 2% Pyrithione Zinc Shampoo Bar with Tea Tree is a solid, soap-free dandruff shampoo bar formulated to help control flaking, itching, and visible scalp buildup while offering a long-lasting, plastic-free alternative to bottled shampoos.

This 4-ounce shampoo bar combines 2% zinc pyrithione with tea tree and peppermint oils in a plant-derived, sulfate-free base to gently cleanse and refresh the scalp. The bar produces a dense, luxurious lather in both hard and soft water and is crafted from primarily plant-based surfactants and conditioning ingredients. It’s free of SLS and designed to be mild and non-drying, while lasting many washes to reduce waste and cost per use.

How should I use this shampoo bar for best results?

Rub the bar directly onto wet hair to build a lather, then massage the foam into the scalp and through hair. Let the product remain on the scalp for at least 30 seconds to allow the zinc pyrithione to work before rinsing thoroughly.

• Wet hair thoroughly, then glide the bar back and forth over the scalp to create foam.
• Massage the lather into roots and lengths for 30–60 seconds.
• Rinse completely and store the bar on a draining tray so it dries between uses.

What ingredients are key and why do they matter?

The active ingredient is 2% zinc pyrithione, paired with tea tree and peppermint oils for a fresh scent and additional cleansing-supportive properties. The surfactants are mostly plant-derived (for example, sodium cocoyl isethionate and coco glucoside), making the bar soap-free and gentle on skin.

• 2% Zinc Pyrithione: main ingredient targeting scalp flaking and irritation-related symptoms.
• Tea Tree & Peppermint Oils: natural-scented essential oils chosen for a cooling, cleansing feel.
• Plant-based Surfactants: SCI, coco glucoside for rich lather without SLS.
• Conditioners: argan oil and oat flour to help maintain moisture and softness.

Will this shampoo bar work for different hair types and water conditions?

The formula is designed to perform in both hard and soft water and is suitable for a variety of hair textures. Because it’s soap-free and includes conditioning agents, it aims to cleanse without stripping natural oils, making it appropriate for normal to oily scalps and many hair types.

• Hard/soft water tested to produce a rich lather.
• Sulfate- and SLS-free formulation to reduce dryness.
• Contains conditioning oils to help with manageability and shine.

How long does a single 4 oz bar last and how should I store it?

A single 4-ounce bar is concentrated and typically lasts several months with daily use, depending on hair length and frequency. To extend its lifespan, keep the bar on a draining soap tray or rack so it dries between washes and avoids sitting in pooled water.

• Daily use can stretch a bar to many weeks or months.
• Store dry between uses on a ventilated dish or rack.
• Avoid leaving it in the shower floor or in standing water to prevent softening.

It’s a good fit for environmentally minded shoppers, travelers who want a solid bar, and anyone looking for a gentle, plant-derived shampoo formulated to be non-drying.
