Well, in this fanfiction, Hermione could be using her intelligence and resourcefulness in many ways. She might consult with other magical beings or experts she knows. She could also try some experimental magic, but always in a cautious way. Since she is so well - read, she may combine different magical theories to come up with a unique way to deal with Harry's scars. It could be a long and complex process that involves trial and error, but Hermione's determination would keep her going.
She might use her magic knowledge. Maybe she tries some healing spells or potions she has learned. For example, she could research in the library to find a special spell that can soothe the pain of the scars or even gradually make them fade.
