It depends on the type of lift that you have done. An endoscopic brow lift leaves only a few tiny incisions, which will be hidden in the hair. A limited-incision brow lift leaves two small incision lines at the outer corners of the forehead, and these are typically completely hidden in the hairline as well. The largest incision is required by the classic brow lift, which leaves an incision line running the length of the forehead right along the hairline. This can generally be angled so that hair can grow through it, camouflaging it nicely.
