How toxic is 5% minoxidil if you don't wash your hands after applying it and eat food? When is it safe to touch my hair?

Thank you for your question. Your main concern should be ingesting any of the Minoxidil by putting your fingers in your mouth or on your food before washing your hands. Always consult with a board certified facial plastic surgeon.Best wishes,

Minoxidil should dry 20-25 minutes after application. It is always best to wash your hands before and after application. Best, Dr. Emer
