The Franchise

Hey Guys, I just started to use the rogaine foam about 4 days ago. Just on the crown of my head being that is where i am losing my hair. But each time i do, I get a crushing headache. I am using the half cap full as instruacted, but it seems to really knock the heck out of me. Both in the morning and at night. I thought it might lessen as i used it more day after day. But no luck so far. I was curious if anyone else has had this issue? If so will the headaches lighten up? Finally i am losing my hair at the crown of my head, and was woundering if you guys could point me in the right direction on something to use. thanks again for taking the time to read this. TF
