BEHENTRIMONIUM METHOSULFATE
Is BEHENTRIMONIUM METHOSULFATE safe for seborrheic dermatitis?
Behentrimonium Methosulfate is context-dependent for seborrheic dermatitis. It is a conditioning and detangling ingredient used mainly in hair products, not a sulfate cleanser despite the word methosulfate in its name.
No applicable exact-ingredient human seb derm or Malassezia study was found. A rinse-off conditioner used on hair lengths creates a different exposure from a leave-on scalp product. If the scalp is flaring, keep rich conditioners away from it when practical and stop any product that repeatedly worsens itch.
