Rogaine wont help. The main ingredient in Rogaine is called Minoxidil. Minoxidil was a blood pressure medication that didnt work very well but had side effects of hair growth. That hair growth was mainly only at the crown.... not the hairline. Wearing a hat will not affect your hairline either... unless it is really really tight. Your hairline is receding because of your genetic code. You are destined for a receding hairline and possibly baldness. This gene is from your mother... Was her father bald? Was your maternal grandmothers father bald? Look into that and see where your future lies with this problem.
