"i want to share this so others can protect themselves. i used microgestin 21 (generic loestrin 21) for one pack. i do not have hair loss on either side of my family. no one in my family has lost their hair. i began losing hair rapidly. within a week it was enough to think maybe i should try rogaine to counter it as much as possible. i just switched to zarah today. fingers crossed that it helps undo what the other drug did."
