Can Rogaine be used to prevent future hair loss if there are no signs of hair loss present yet?

Hi, I am a 37 year old female. I experienced some noticeable shedding in 2013. I have been going to a hair specialist for the last 3 years and gotten examined, he has said that, “no apparent female pattern loss.” was present for the last 3 years. However, there is female pattern hairloss in my family, so he recommended using Rogaine to prevent it. My question is can Rogaine be used as a preventative medicine to avoid experiencing hairloss in the future?
