Top 5 Medicated Shampoos in Canada, 2026
Published on Monday, February 2, 2026
Medicated shampoos treat specific scalp conditions with proven over-the-counter active ingredients rather than just cleansing the hair. The right choice depends on what you are treating: ketoconazole (Nizoral) and selenium sulfide (Head & Shoulders Clinical Strength, Selsun Blue) are antifungals that target the yeast behind dandruff and seborrheic dermatitis, coal tar (Neutrogena T/Gel) slows the rapid skin-cell turnover seen in psoriasis and seborrheic dermatitis, and dimethicone-based treatments (Nix Ultra) physically smother head lice without pesticides. This guide compares five of the most widely available medicated shampoos and lice treatments in Canada in 2026, with their active ingredients and what each one is best suited to treat. For persistent, severe or spreading scalp problems, see a pharmacist or physician, as some conditions need prescription-strength treatment.
