⚠️ Don’t use on broken skin – The starch can feed bacteria in open wounds.
⚠️ Rinse thoroughly – When using on hair, rinse well to prevent starch buildup, which can make hair stiff.
⚠️ Not for daily use – 1-2 times per week is plenty for most applications.
⚠️ Discard if moldy – If you see mold, throw it out and start fresh.
