DHS Zinc Shampoo dandruff treatment 16 oz — 2% Zinc Pyrithione for flaky, dry scalp

DHS Zinc Shampoo is a 16 oz dandruff shampoo formulated with 2% zinc pyrithione to calm flaky, dry scalps and reduce visible flakes.

Delivering a clinical-strength active ingredient in a gentle cleansing base, this formula is designed to control the flaking and itching associated with dandruff and seborrheic dermatitis flare-ups while leaving hair soft and manageable. The 16-ounce bottle provides multiple uses and is free of PABA and TEA lauryl sulfate, making it a practical choice for routine scalp care. Use as directed several times a week and alternate with a regular shampoo when not treating symptoms.

How quickly will I notice fewer flakes?

Many users report visible improvement after the first few washes, thanks to the 2% zinc pyrithione ingredient that targets the factors commonly linked to flaking. Results can vary depending on scalp condition and frequency of use.

• Active 2% zinc pyrithione to help reduce flaking.
• Gentle cleansing base that rinses clean without heavy residue.
• Recommended frequency: 3–4 times per week during flare-ups.

Will this shampoo be harsh on my hair or color-treated strands?

DHS Zinc Shampoo is formulated to be gentle on hair while addressing scalp issues; it does not contain PABA or TEA lauryl sulfate, ingredients some users avoid. For color-treated hair, alternating with a milder everyday shampoo helps preserve color vibrancy while maintaining scalp control.

• PABA-free and TEA lauryl sulfate-free formula.
• Leaves hair feeling softer and with shine when used as directed.
• Pair with a regular DHS shampoo on non-treatment days for balance.

How should I use DHS Zinc Shampoo for best results?

Apply to wet hair, lather into the scalp, and leave on for about one to three minutes before rinsing to allow the active ingredient to work. Use three to four times weekly while symptoms persist, then reduce frequency as directed by your doctor or as symptoms improve.

• Wet hair thoroughly, apply, and massage into scalp.
• Allow 1–3 minutes contact time for the zinc pyrithione to act.
• Rinse completely; alternate with DHS Regular or Clear Shampoo on other days.
