The medicated shampoo market is highly competitive, with key players like Procter & Gamble (Head & Shoulders), Johnson & Johnson (Neutrogena T/Gel), Sanofi (Selsun Blue), and Prestige Consumer Healthcare (Nizoral) leading the global landscape. These companies compete on product efficacy, dermatological backing, and ingredient innovation. Emerging brands are gaining traction by offering natural, sulfate-free formulations and targeting niche scalp conditions. E-commerce platforms and direct-to-consumer strategies have intensified competition, allowing smaller players to challenge established brands. Continuous R&D, strategic partnerships, and expanding into high-growth regions like Asia-Pacific are critical tactics for maintaining market share in this rapidly evolving segment.
