Klinique Active Shampoo is a medicated formulation containing Cetrimide 2% w/v and Ketoconazole 0.5% w/v, designed for the effective management of dandruff and seborrheic dermatitis. Cetrimide, a quaternary ammonium compound, exhibits potent antiseptic and cleansing properties, aiding in the removal of debris and reducing microbial load on the scalp. Ketoconazole, a broad-spectrum antifungal agent, inhibits the synthesis of ergosterol, an essential component of fungal cell membranes, thereby exerting fungistatic and fungicidal effects against Malassezia species, which are commonly implicated in dandruff and seborrheic dermatitis. Klinique Active Shampoo is indicated for patients presenting with flaky, itchy, and inflamed scalp conditions associated with fungal overgrowth. The shampoo facilitates symptomatic relief by reducing scaling, itching, and redness, promoting scalp health. It is suitable for topical use on the scalp and should be applied as directed, typically 2-3 times per week for optimal results. Caution is advised in individuals with hypersensitivity to any of the ingredients. Continued use may be necessary to prevent recurrence. This product should be used under medical supervision, especially in patients with extensive skin conditions or those using concomitant topical therapies.
