Do not try to dry the Minoxidil quicker (like using a hairdryer) as this can make it less effective.
Do not apply Minoxidil right before going to bed—it’s going to rub off on your bed potentially staining it and your beard is losing out.
When you have Minoxidil on, do not kiss or rub your face on other people—you’re losing product and potentially giving others unwanted hair.
Minoxidil is toxic to cats. Minoxidil can get dogs sick as well. So keep Minoxidil away from pets [post]. Goes without saying to keep Minoxidil away from kids.
