Rogaine on healthy female hair that’s just fine textured and wispy around temples? (Photo)

I am so confused and have read so much contradicting advice regarding use of Rogaine on “normal” or “healthy” hair that i just want to boost already fine hair. I’m in my mid 30s. In my earlier 20s, my hair was somewhat healthier or youthful looking. But who’s isn’t really. It’s still pretty today. Or was. I started using “Hers” 2% minoxidil treatment two months ago and have lost almost half of my hair. But I read shedding is normal. However I another concern is the texture of new hair.
