If you use Rogain for women after pregnancy, do you think that would help keep the new hair growth?

Rogaine has a 40% success rate. Try Nettle Leaves or Stinging Nettle. 1000 mg a day and your hair will be back in no time! Rogaine is 8 months to see results. It should come back naturally anyway, but the nettle leaves will help it along. And it is safe if you are breastfeeding.
