Hi there!
Forehead lowering surgery and hairline advancement surgery should be performed by a qualified, accredited, board-certified plastic surgeon. These procedures are often performed in isolation or as part of forehead rejuvenation/lift, and require intricate knowledge of the anatomy to reduce the risk of nerve or vessel damage. Also, delicate plastic surgery techniques, such as hiding the hairline incision and plastic surgical suturing, need to be performed to minimize the appearance of scars.
Hope this helps!
