What is good at preventing the loss of hair in a womans head. I am 55 years old and my fringe area is thinning

I had the same problem and I have been using Rogaine for 6 years. My hair is still thin on the top, but not as thin as before and it is not getting any thinner. In fact, I am now using Equate Hair Regrowth for Women which has all the same ingredients as Rogaine, but is 1/3 the price. You will have to use it twice a day and for the rest of your life to keep your hair from falling out. I made it part of my daily routine and it is very easy to do. It comes with a dropper (looks like an eye dropper) and you use 6 drops and message it into your scalp twice a day and Walla! In 6 months, you will actually feel your hair growing in because it will feel like whiskers on your head, then all of a sudden your thinning hair will get thicker. Give it at least 6 months and have patience because it does work!
