Not applicable for systemic elimination; local retention on hair/scalp lasts until next wash (typically 24-48 hours).
Not well characterized due to minimal systemic absorption; estimated to be 2-3 hours in plasma if absorbed.
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 fecal via biliary elimination; less than 5% renal excretion of absorbed dose.
