My hair was pulled out Wednesday night. I have Itching. Swelling.. ect. Is it safe to use Womens Rogaine? (photo)

Location is in the back of my scalp rather than the sides or top. Hair is naturally baby fine but I wouldn't consider my hair thick or thin. Somewhere in the middle. I may have a little redness but no pain or irratation. I am starting to take biotin along with prenatal for hair,skin ect. Just want to make sure the Rogaine will not do more damage than good. This happened about 72hrs ago. Please help.
