You can't know if you will have side effects until you take the treatment. Many people for some reason decide that they're going to have them, before they take it, and adjust all kinds of things including dosage, before they even pop their first pill.
Take 1mg daily for 30 days. See how you fare on it. Its not like the side FX aren't reversible. If at the 30 day mark you're doing fine, you are likely to be fine at 1mg forever, and you'll have optimal chances of success with your hair as well.
