Why Not Just Wash Your Hands After Applying Rogaine Foam?

This is a follow-up question I received from Should I Be Applying Rogaine with a Rubber Glove?

once you apply Rogaine foam can’t you simply wash your hands with anti-bacterial liquid soap instead of wearing a glove?

The minoxidil absorption is probably fast, but I do not know how fast. If you are absorbing it with more hand hair, then a glove is the only guarantee to stop it getting through the skin and into your hands and body.
