Nizoral Anti-Dandruff Shampoo 1% Ketoconazole, Fresh Scent 7 fl oz — Twice-Weekly, Color-Safe

Nizoral Anti-Dandruff Shampoo is a prescription-strength over-the-counter shampoo that uses 1% ketoconazole to target and reduce dandruff-related flaking, scaling, and itching with a fresh scent.

This concentrated formula is designed for targeted use — apply it just twice weekly between regular hair-cleansing routines to manage dandruff symptoms without daily use. Nizoral works differently from ordinary shampoos by focusing on the scalp’s underlying fungal cause, while remaining gentle on color-treated or chemically processed hair. The 7 fl oz size fits easily into a shower caddy and lasts several weeks with twice-weekly application.

How should I use Nizoral in my weekly hair routine?

Use Nizoral in place of your normal shampoo two times per week on non-consecutive days. Lather into wet hair, leave on the scalp for about 3–5 minutes so the active ingredient can work, then rinse thoroughly. On other days, you can use your regular shampoo and conditioner as usual.

• Apply to wet hair and massage gently into the scalp.
• Leave on for 3–5 minutes before rinsing for best contact time.
• Use twice weekly; do not exceed directed frequency.

What does ketoconazole 1% do that other shampoos don't?

Ketoconazole 1% is an antifungal ingredient that targets the scalp organisms linked to dandruff, helping reduce flaking and irritation rather than just masking symptoms. Laboratory testing shows it is substantially more effective at eliminating the scalp fungus than some common dandruff actives. Because it works on the root cause, many users report visible improvement after a few washes.

• Direct antifungal action to address the cause of dandruff.
• Clinically proven formulation for flake and itch reduction.
• Effective in only two treatments per week when used as directed.

Will Nizoral affect color-treated or chemically processed hair?

Nizoral is formulated to be gentle on color-treated, highlighted, or gray hair when used according to instructions. The shampoo focuses on the scalp and rinses clean without leaving heavy residue, preserving color and manageability. If you have specific concerns about a recent chemical service, patch testing or consulting your stylist can help.

• Safe for most color-treated and chemically processed hair.
• Rinses clean to maintain hair texture and shine.
• Use only as directed to avoid excess dryness.

How quickly will I notice results and are there side effects?

Many users see reduced flaking and itching within a few washes, though individual response times vary. Mild irritation or dryness can occur in some people; if discomfort persists, discontinue use and consult a healthcare professional. Follow the labeled directions and avoid daily use unless otherwise instructed by a clinician.

• Improvement often visible after several applications.
• Possible mild scalp dryness or irritation in sensitive individuals.
• Stop use and seek advice if persistent irritation occurs.

Who is this for: Nizoral 1% Ketoconazole shampoo is for people seeking a powerful, targeted solution for dandruff that fits into a regular haircare routine. It suits those with moderate to severe flaking or itching who want a product that attacks the underlying fungal cause while remaining gentle enough for treated hair. If you prefer intermittent, twice-weekly treatment rather than a daily medicated wash, this concentrated 7 fl oz bottle is a compact, effective option.
