Regaine for women contains Minoxidil 2% which is thought to work by helping the flow of blood to your hair follicles on your scalp. BR> Regaine for women should be used twice daily for a period of 4 months before you begin to see new hair re-growth. In clinical studies 3 out of every 5 women reported hair re-growth after 8 months when using the product continually. If you do not continue to use Regaine the hair that has re-grown may disappear after 3-4 months causing further balding or hair loss.
