Head & Shoulders is the world's most widely used anti-dandruff range, built around zinc pyrithione, an active ingredient that targets the Malassezia fungus at the root of flaking and scalp irritation. The line-up at Ronaghan's Pharmacy spans everyday anti-dandruff shampoos, moisturising variants for dry scalp, 2-in-1 shampoo and conditioner combinations, and larger 400 ml and 1000 ml formats suited to regular household use. Choosing between variants is straightforward. Classic Clean and Clean & Balanced work well for routine dandruff control on normal hair, while Dry Scalp Care and Smooth & Silky address dryness and frizz alongside flaking. The conditioner range complements each shampoo, helping restore softness that medicated washing can sometimes reduce. For persistent or severe scaling that does not respond to zinc pyrithione, a pharmacist may suggest alternating with a ketoconazole-based product such as Nizoral. Both are stocked here and are safe to use in rotation. All Head & Shoulders products are pH-balanced and dermatologically tested for regular use, making them appropriate for most hair types including colour-treated hair.
