12 weeks post. Baldness near incision line after brow reduction surgery. Will the hair regrow?

I had a brow reduction surgery a bit over 12 weeks ago. As you can see in the photo, there’s baldness near the area of the incisions. It’s worse on one side than the other. My doctor told me I should wait six months for it to regrow and that a hair transplant is an option if it doesn’t. I’d really rather not have to get a hair transplant. How common is hair loss as a result of this treatment and do you believe the hair will regrow? Thank you.
