HEAD & SHOULDERS CONDITIONER vs KETOZOLE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Not applicable; this is a cosmetic conditioner. No pharmacological mechanism.
Ketoconazole is an imidazole antifungal agent that inhibits fungal cytochrome P450 14α-demethylase, thereby blocking the conversion of lanosterol to ergosterol, a key component of the fungal cell membrane. This leads to increased membrane permeability and cell death.
Not applicable. Head & Shoulders Conditioner is a cosmetic product for external use on hair and scalp; no systemic dosing.
200 mg orally once daily with food.

Not applicable for systemic elimination; local retention on hair/scalp lasts until next wash (typically 24-48 hours).
Terminal elimination half-life is approximately 2 hours (range 1.5–3.5 hours). Clinically, duration of antifungal effect extends beyond plasma half-life due to persistent tissue levels.
Renal (urine): <1% unchanged; biliary/fecal: <1% as parent compound; majority remains on hair/scalp and is removed via washing and shedding. Systemic absorption negligible.
Primarily hepatic metabolism; renal excretion of unchanged drug <1%. Biliary/fecal excretion accounts for ~20-35% of metabolites.
